Operating principle
KeyPad Combi combines two devices: a siren and a keypad with RFID card and key fob support. This means that the same device may be used to manage the security modes and to notify about system alarms and events.
Security management
KeyPad Combi arms and disarms the security of the entire facility or separate groups and allows activating the Night Mode. You can manage the security modes using:
- Codes. KeyPad Combi supports general and personal codes, as well as arming without entering a code.
- Cards or key fobs. To quickly and securely identify users, KeyPad Combi uses the DESFire® technology. DESFire® is based on the ISO 14443 international standard and combines 128-bit encryption and copy protection.
KeyPad Combi supports code types as follows:
- Keypad code — general code set up for the keypad. When used, all events are delivered to Ajax apps on behalf of the keypad.
- User code — personal code set up for users connected to the hub. When used, all events are delivered to Ajax apps on behalf of the user.
- Keypad access code — set up for a person who is not registered in the system. When used, events are delivered to Ajax apps with a name associated with this code.
- RRU code is an access code for the rapid response units (RRU) activated after the alarm and valid for a specified period. When the code is activated and used, events are delivered to Ajax apps with a title associated with this code.
The number of personal, access, and RRU codes depends on the hub model.
Before entering a code or using Tag/Pass, you should activate (“wake up”) KeyPad Combi by sliding your hand over the touch panel from top to bottom. Once you activate the device, the security status indication turns on, and the device beeps. The security status is only displayed when KeyPad Combi is active.
Pressing of the buttons is accompanied by a sound signal. If you do not touch the keypad for 12 seconds, KeyPad Combi goes into power-saving mode and turns off the display of the current arming mode.
Keep in mind that KeyPad Combi has no touch buttons or cards/tags reader backlight.
Using the siren
KeyPad Combi includes a fully functional Ajax security system siren. The device has 2 tasks:
- Informing about alarms. The device responds to triggering of the tamper and security system alarms in less than a second by turning on the siren, which scares off intruders and attracts the attention of neighbors.
- Indicating the security status. The siren may notify on the arming mode change as well as on entry/exit delays.
Function button
KeyPad Combi has a Function button that operates in 3 modes:
- Off — the button is disabled and nothing happens after it is pressed.
- Alarm — after the Function button is pressed, the system sends an alarm to the security company monitoring station and all users.
- Mute Interconnected Fire Alarm — after the Function button is pressed, the system mutes the alarm of the Ajax fire detectors. Keep in mind that this option functions only if interconnected alarms of fire detectors are active.
Duress code
KeyPad Combi supports duress code. It allows you to simulate alarm deactivation. The Ajax app and sirens installed at the facility will not give you away in this case, and the security company and other users of the security system will be warned about the incident.
Two-stage arming
KeyPad Combi can participate in two-stage arming but cannot be used as a second-stage device. The two-stage arming process using Tag or Pass is similar to arming using a personal or general code.
Event transmission to the monitoring station
The Ajax security system can connect to the CMS and transmit events and alarms to the monitoring station of the security company in SurGard (Contact ID), SIA DC-09, and other proprietary protocol formats. A complete list of supported protocols is available here. The device ID and the number of the loop (zone) can be found in its states.
Connection
KeyPad Combi is incompatible with Hub, third-party security central units, and ocBridge Plus and uartBridge integration modules.
Before starting connection
- Install the Ajax app and create an account. Add a hub and create at least one room.
- Make sure that the hub is on and has Internet access (via Ethernet cable, Wi-Fi, and/or mobile network). This can be done by opening the Ajax app or by looking at the hub logo on the faceplate — it lights white or green if the hub is connected to the network.
- Make sure that the hub is disarmed and does not start updates by checking its status in the Ajax app.
Only a user or PRO with full admin rights can add a device to the hub.
To connect KeyPad Combi
- Open the Ajax app. If your account has access to multiple hubs, select the one to which you want to connect KeyPad Combi.
- Go to the Devices menu and click Add Device.
- Name the device, scan or enter the QR code (located on the package and under the SmartBracket mount), and select a room.
- Click Add; the countdown will begin.
- Switch on the device by holding the power button for 3 seconds. Once connected, KeyPad Combi will appear in the hub device list in the app. To connect, locate the device at the same protected facility as the system (within the coverage area of the hub radio network range). If the connection fails, try again in 10 seconds.
The device only works with one hub. When connected to a new hub, the device stops sending commands to the old hub. Once added to a new hub, KeyPad Combi is not removed from the device list of the old hub. This must be done manually through the Ajax app.
KeyPad Combi turns off automatically 6 seconds after being turned on if the device fails to connect to the hub. Therefore, you do not need to turn off the device to retry the connection.
Updating the statuses of devices in the list depends on the Jeweller settings; the default value is 36 seconds.

Setting up the processing of detector alarms
You can use the Ajax app to specify the detectors to which the siren will respond if an alarm is triggered. This is necessary to avoid situations when the security system notifies of an alarm from a detector to which the siren should not respond at the facility, for example, from the LeaksProtect detector.
The parameter is adjusted in the settings of a detector or device to which the siren should not respond.
To disable siren response to alarms from a specific detector or device, in the Ajax app:
- Go to the Devices menu.
- Select the detector or device.
- Go to Settings and set the necessary parameters for activating the siren.
Setting the tamper alarm response
The KeyPad Combi siren can respond to tamper alarms. The option is disabled by default. Note that the tamper reacts to the opening and closing of the lid even if the system is not armed!
For the KeyPad Combi siren to respond to tamper triggering, in Ajax app:
- Go to the Devices menu.
- Select a hub (at the top of the list).
- Go to Settings .
- Select the Service item.
- Go to Siren Settings.
- Enable the Alert with a siren if the hub or detector lid is open option.
Setting the response to pressing the panic button in the Ajax app
The KeyPad Combi siren can respond to pressing the panic button in Ajax apps. Note that the panic button can be pressed even if the system is disarmed!
For the siren to respond to pressing the panic button, in the Ajax app:
- Go to the Devices menu.

Configuring codes
Ajax security system allows you to set up a keypad code, as well as personal codes for users added to the hub.
With the OS Malevich 2.13.1 update, we have also added the ability to create access codes for unregistered people who are not added to the hub. This is convenient, for example, to provide a cleaning company with access to security management. See how to set up and use each type of code below.
To set keypad code
- Go to keyboard settings.
- Select Keypad Code.
- Set the keypad code you want.
To set the keypad duress code
- Go to keypad settings.
- Select Duress Code.
- Set the keypad duress code you want.
To set a personal code in the Ajax app
- Go to the user profile settings (Hub → Settings → Users → Your profile settings).
- Select Passcode Settings (User ID is also visible in this menu).
- Set User Code and Duress Code.
Each user sets a personal code individually. The hub admin cannot set the codes for all users.
To set up an access code for a person who is not registered in the system
- Go to the hub settings (Hub → Settings ).
- Select Keypad Access Codes.
- Set up Username and Access Code.
If you want to set up a duress code, change settings for access to groups, Night Mode, code ID, temporarily disable or delete this code, select it in the list and make changes.
PRO or a user with admin rights can set up an access code or change its settings. This function is supported by hubs with OS Malevich 2.13.1 and higher. Access codes are not supported by the Hub control panel.
To set up the RRU code
Only a PRO with the rights to configure the system can create and configure the RRU codes in the Ajax PRO apps. More information about configuring this feature you can find in this article.
The RRU codes are supported by hubs (except the Hub model) with OS Malevich 2.17 and higher.
Cards and key fobs adding
KeyPad Combi can work with Tag key fobs, Pass cards, and third-party devices that support DESFire® technology.
Before adding third-party devices that support DESFire®, make sure they have enough free memory to handle the new keypad. Preferably, the third-party device should be pre-formatted.
The maximum number of connected Passes and Tags depends on the hub model. The connected Passes and Tags do not affect the total limit of devices on the hub.
| Hub model | Number of Tag or Pass devices |
| Hub Plus | 99 |
| Hub 2 | 50 |
| Hub 2 Plus | 200 |
The procedure for connecting Tag, Pass, and third-party cards and key fobs is the same. See the connecting instructions here.
Controlling security via codes
You can control Night mode, the security of the entire object or individual groups using general or personal codes and access codes (configured by PRO or a user with admin rights). KeyPad Combi supports 4 to 6 digit codes. Incorrectly entered numbers can be cleared with the 
button.
If a personal code or access code is used, the name of the user who armed or disarmed the system is displayed in the hub event feed and in the notifications list. If a general code is used, the name of the user who changed the security mode is not displayed.
Keypad access codes support hubs with OS Malevich 2.13.1 and higher. Hub control panel does not support this function.

Mute Interconnected Fire Alarm function
KeyPad Combi can mute the fire alarm by pressing the Function button (if the required setting is enabled). The reaction of the system to pressing a button depends on the settings and the state of the system:
- Interconnected FireProtect Alarms have already propagated — by the first press of the Function button, all sirens of the fire detectors are muted, except for those that registered the alarm. Pressing the button again mutes the remaining detectors.
- Interconnected alarms delay time lasts — by pressing the Function button, the siren of the triggered Ajax fire detectors is muted.
Note that the option is active only if Interconnected FireProtect Alarms is enabled in the hub settings.
With the OS Malevich 2.12 update, users can mute fire alarms in their groups without affecting detectors in the groups to which they do not have access.
Indication
KeyPad Combi indicates alarms, delays when entering/leaving, current security mode, button pressing, malfunctions, and its own status with LEDs and beeps.
The current security mode is displayed using corresponding LEDs after KeyPad Combi activation. The information about the current security mode is relevant even if the arming mode is changed by another device: a key fob, another keypad, or an app.
You can activate KeyPad Combi by swiping your hand over the touch panel from top to bottom. When activated, the current security status backlight on the device will turn on and a beep will sound (if enabled).

Sound notifications of malfunctions appear when the keypad indication is finished. If several malfunctions occur in the system, the keypad will notify about the loss of connection between the device and the hub first.
Functionality testing
The Ajax security system provides several types of tests that help you make sure that installation points of devices are selected correctly.
KeyPad Combi functionality tests start instantly, irrespective of the hub-detector ping period (36 seconds with the standard settings of the hub).
The tests are available in the device settings menu (Ajax App → Devices → KeyPad Combi → Settings 
):
Choosing a location
KeyPad Combi is best placed indoors near the entrance. This allows disarming the system before the entry delays have expired, as well as quickly arming the system when leaving the premises.
When holding KeyPad Combi in your hands or using it on a table, we cannot guarantee that the touch buttons will work properly.
It is a good practice to install KeyPad Combi 1.3 to 1.5 meters above the floor for convenience. Install the device on a flat, vertical surface. This allows KeyPad Combi to be firmly attached to the surface and to avoid false tamper triggering.
When choosing the location, also take into account the following factors: signal strength, convenience of use, and siren audibility.
Signal strength
Install KeyPad Combi in a place with stable Jeweller signal strength (2-3 bars in the Ajax app). When selecting the place for installation, consider the distance between the detector and the hub or radio signal range extender and the presence of obstacles between the devices that block the radio signal: walls, floors, large objects located in the room.
Be sure to check the Jeweller signal strength at the installation site. If the signal strength is low (a single bar), we cannot guarantee a stable operation of the security system! At the very least, relocate the device as repositioning even by 20 cm can significantly improve the signal reception.
If after moving the KeyPad Combi still has a low or unstable signal strength, use a radio signal range extender.
Convenience of use and audibility of the siren
Install KeyPad Combi so that it is convenient to use it. The device should not be obstructed with various objects, and access to the device should be free of obstacles. Also take into account the siren audibility. If the device is installed in an improper place, this may result in the siren signal being inaudible in another room or premise.
Do not install KeyPad Combi:
- In places where parts of clothing (for example, next to the hanger), power cables, or Ethernet wire may obstruct the device keypad. This can lead to false triggering of the keypad.
- Inside premises with temperature and humidity outside the permissible limits. This could damage the device.
- Near metal objects and mirrors (they can shield the radio signal and lead to its attenuation).
- In places where KeyPad Combi has an unstable or poor signal strength with the hub or radio signal range extender.
- Within 1 meter of a hub or radio signal range extender. This could result in the loss of connection with the keypad.
- Near the glass break detectors. The siren sound may trigger an alarm.
- Close to electrical wiring. This may cause communication interferences.
- Outdoors. This could damage the device.
- In places where the audio signal can be jammed.
Installation of KeyPad Combi
Prior to installing KeyPad Combi, be sure to select the optimal location following the requirements of this manual!
- Attach KeyPad Combi to the surface with double-sided adhesive tape and carry out signal strength and attenuation tests. If the signal strength is unstable or if a single bar is displayed, move the device or use a radio signal range extender.
Double-sided adhesive tape may only be used for temporary attachment of KeyPad Combi. The device attached with adhesive tape can at any time be detached from the surface and fall, which may lead to failure. Please note that if the device is attached with adhesive tape, the tamper will not trigger when trying to detach it.
- Conduct the volume level test. If KeyPad Combi is hardly audible, relocate the device or change the volume level in the device settings.
- Make sure it is convenient to enter codes or use Tag/Pass. Relocate KeyPad Combi if it is inconvenient to manage the security at the selected location.
- Remove the device from the SmartBracket mounting plate.
- Attach the SmartBracket mounting plate to the surface using the bundled screws. When attaching, use at least two fixing points. Be sure to fix the perforated corner on the SmartBracket plate so that the tamper responds to a detachment attempt.
- Slide KeyPad Combi onto the mounting plate and tighten the mounting screw at the bottom of the body. The screw is needed for more reliable fastening and protection of KeyPad Combi from quick dismantling.
- As soon as the device is fixed on SmartBracket, it shall blink once with LED X (Malfunction) — this is a signal that the tamper has been triggered. If the LED does not blink after installation on SmartBracket, check the tamper status in the Ajax app and make sure the plate is firmly attached.
Maintenance
Conduct KeyPad Combi functionality tests regularly. The optimal frequency of testing is once a week. Clean the body from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth that is suitable for equipment care.
Do not use substances that contain alcohol, acetone, gasoline or other active solvents to clean the detector. Wipe the touch keypad gently: scratches can reduce the sensitivity of the keypad.
The batteries installed in KeyPad Combi provide up to 3.5 years of autonomous operation at default settings. If the battery is low, the system sends appropriate notifications, and LED X (Malfunction) smoothly lights up and goes out after each successful password entry.
KeyPad Combi can work up to 2 months after the low battery signal. However, we recommend you replace the batteries immediately upon notification.
It is advisable to use lithium batteries. They have a large capacity and are less affected by temperatures.
