DoorProtect Plus User Manual

Updated

DoorProtect Plus is a wireless opening, shock, and tilt detector, that operates within the Ajax security system, connecting via the protected Jeweller radio protocol. The communication range is up to 1,200 m line of sight. DoorProtect Plus can operate up to 5 years from a pre-installed battery and capable to detect more than one million openings.

The user can configure the detector via the Ajax app for iOS, macOS, Windows, or Android. The app notifies the user of all events through push notifications, SMS, and calls (if activated).

DoorProtect Plus does not support connecting via the Ajax uartBridge or Ajax ocBridge Plus integration modules.

The Ajax security system can be connected to a central monitoring station of a security company.

Operating Principle

DoorProtect Plus consists of two parts: the detector and the constant magnet. The detector is equipped with the sealed contact reed relay, built-in accelerometer, and socket for a third-party wired detector.

Attach the detector to the door frame, while the magnet can be attached to the moving wing or sliding part of the door. If the sealed contact reed relay is within the coverage area of the magnetic field, it closes the circuit, which means that the detector is closed. The opening of the door pushes out the magnet from the sealed contact reed relay and opens the circuit. In such a way, the detector recognizes the opening.

The DoorProtect Plus set includes two constant magnets. The small one works at a distance of 1 cm, and the big one — up to 2 cm.

The detector can be positioned horizontally. If there is no need to detect opening, use only the detector part (without magnets) and disable the primary detector in the settings.

The accelerometer detects shocks and vertical deviation relative to the initial position of more than 5°. DoorProtect Plus can be installed on windows, including dormer windows, and the system can be armed when they are slightly open (disable the primary detector in the settings рreviously).ajax doorprotect plus

If triggered, DoorProtect Plus immediately transmits the alarm signal to the hub, activating the sirens and notifying the user and security company.

Connecting

Before starting connection

  1. Following the hub user guide, install the Ajax app. Create the account, add the hub, and create at least one room.
  2. Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
  3. Make sure that the hub is disarmed and does not update by checking its status in the Ajax app.

Only users with administrator rights can add the device to the hub.

How to connect the detector to the hub

  1. Select Add Device in the Ajax app.
  2. Name the device, scan or type the QR code (located on the detector body and packaging), and select the location room.

  3. Tap Add — the countdown will start.
  4. Switch on the device.
    ajax doorprotect plus

For detection and pairing to occur, the detector should be located within the coverage area of the wireless network of the hub (at a single protected object). The connection request is transmitted for a short time: at the moment of switching on the device.

If the device failed to pair (LED blinks once per second), switch it off for 5 seconds and retry. The detector connected to the hub appears in the list of devices in the app. The update of the detector statuses in the list depends on the device ping interval set in the hub settings (the default value is 36 seconds).

Performance testing

The Ajax security system allows conducting tests for checking the functionality of connected devices.

The tests do not start immediately but within 36 seconds by default. The starting time depends on the ping interval (the paragraph on “Jeweller” settings in hub settings).

Attenuation Test

Installing the Detector

The location of DoorProtect Plus depends on its remoteness from the hub, and obstacles hindering the radio signal transmission: walls, floors, large objects inside the room.

Check the Jeweller signal level at the installation location

If the signal level is low (one bar), we cannot guarantee the stable operation of the detector. Take all possible measures to improve the quality of the signal. At least, move the detector: even a 20 cm shift can significantly improve the quality of signal reception.

If the detector has low or unstable signal strength even after moving, use a ReX radio signal range extender.

Do not install the detector:

  1. outside the premises (outdoors);
  2. nearby any metal objects or mirrors causing attenuation or screening of the signal;
  3. at any places with fast air circulation (air fans, open windows or doors);
  4. inside premises with the temperature and humidity beyond the range of permissible limits;
  5. closer than 1 m to the hub.

Attach the magnet to the right of the detector. The detector is located either inside or outside the door case (window frame):

ajax doorprotect plus

When installing the detector in the perpendicular planes (inside the case/frame), use the small magnet from the set. The distance between the magnet and detector should not exceed 1 cm.

When positioning the parts of DoorProtect Plus in the same plane, use the big magnet. Its actuation threshold is 2 cm.

Detector Testing

Having defined the location, fix the detector and magnet with the double-sided adhesive tape and check its operation of using the Detection Zone test.

In the test mode, the DoorProtect Plus LED lights continuously, switching off for a second, if the detector is triggered. Check the correct operation of the device by opening/closing the door several times.

Connecting a Third-Party Wired Detector

A wired detector with an NC (normally closed) contact type can be connected to DoorProtect Plus using the in-built terminal clamp.

ajax doorprotect plus

We recommend installing the wired detector at a distance no longer than 1 meter to DoorProtect Plus. Longer wire length increases the risk of its damage and reduces the quality of communication between the detectors.

To put out the wire from the detector body, break out the plug:

ajax doorprotect plus

If the connected wired detector is triggered, you receive the notification.

To make sure the alarm is raised when the roller shutter is opened, connect the wired roller shutter motion detector with the NC (normally closed) contact to DoorProtect Plus. The function is available for the devices with firmware version 5.53.1.0 and higher.

Installation

Before installing the detector, make sure that you have selected the optimal location that follows the guidelines of this manual!

  1. Fix the SmartBracket attachment panel using bundled screws. If you use any other attachment tools, make sure that they do not damage or deform the attachment panel.

    Use double-side adhesive tape only for temporary attachment of the detector. The tape runs dry with time, which can cause falling, false triggering, and detector malfunction.

  2. Put the detector on the attachment panel. When the detector is fixed in SmartBracket, it blinks with LED, signaling that the tamper is closed. If LED doesn’t blink after fixing in SmartBracket, check the status of the tamper in the Ajax app and then the fixing tightness of the panel.

    If someone detaches the detector from the surface or takes it off the attachment panel, the security system notifies you.

  3. Put the magnet on the attachment panel.

Maintenance

Check the operational capability of the detector regularly. Clean the detector body from dust, spider web, and other contaminants as they appear. Use soft dry napkin suitable for tech equipment.

Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to clean the detector.

The battery life depends on its quality, detector triggering frequency, and ping interval by the hub.

If the door opens 10 times a day and the detector ping interval is 60 seconds, then DoorProtect Plus operates 7 years from the pre-installed battery. For instance, a 12-seconds ping interval reduces the battery life to 2 years.

If the detector battery is low, the system notifies the user, and the LED indicator smoothly lights up and goes off if a glass break is detected or the tamper is triggered.
