What is Chime, and how does this function work

Updated

When Chime (opening notifications) is enabled, the sirens make a special sound to indicate that the opening detectors are triggered when the system is disarmed. The feature is used, for example, in stores to notify employees that someone has entered the building.

Only Hub Plus, Hub 2 and Hub 2 Plus on OS Malevich 2.12 and higher supports chime feature. If you have a standard hub, you can replace it with a new model and transfer devices and settings in a minute.

How chime function works

ajax opening alerts

If the feature is enabled, the sirens signal opening of a door when the system is disarmed. The sound is short and is a little quieter than the alert sound. You can set the number of signals for each detector when triggered, from 1 to 4.

The feature affects neither the work of the sirens when armed nor the indication of delays when entering/leaving. When the system is armed, the sirens signal alarms with the volume and duration as in settings.

When the feature is enabled, detector triggering notifications are not sent to the Ajax apps or the security station. Only sirens at the facility notify about the triggering.

Sirens can signal the opening of a single detector, a group of detectors, or all detectors at the facility. You can also choose which sirens will notify you about the triggering.

Opening notifications only work with bistable detectors. A list of devices suitable for chime is provided below.

How chime works in the group mode

When the group mode is activated, the sirens can be assigned to groups or work with the entire system (by default).

If a siren is assigned to a group, it can notify the triggering of the detectors assigned to the same group. This is useful if you want the siren to respond to events of certain detectors.

If the siren works with the entire system, it can notify about the triggering of any detectors in the system.

Chime specifics

This feature can be set up by a user or a PRO with administrator rights. A user without administrator rights can activate the feature if they have the right to Enable chime.

New users, as well as current users and PROs with administrator rights, have the right to enable chime by default. A PRO without the rights to set up the system cannot set up chime.

A siren and a detector can be connected to different range extenders. Connecting to different range extenders affects only the siren signal delay after a detector is triggered. The maximum delay is 0.6 seconds.

If a siren and a detector are connected to the same range extender, and this range extender loses connection with the hub, the siren will still notify about the opening detector triggering.

Chime do not work if the siren or the detector is temporarily disabled, either automatically or manually.

Chime do not work if the detector or the siren lose connection with a hub or a range extender.

The feature is available on sirens with firmware versions as follows:

Opening detectors and sirens do not indicate LEDs in case of triggering in disarmed mode when chimes are enabled.

How to temporarily disable Chime

With the group mode off

  1. Sign in to the Ajax app.
  2. Select a hub if you have several of them or if you are using the PRO app.
  3. Go to the Control menu.
  4. Click on the blue bell icon in the upper right corner of the screen.

The bell will turn white, and all users will be notified accordingly in the Ajax app. To turn the notifications back on, press the white bell.

With the group mode on

  1. Sign in to the Ajax app.
  2. Select a hub if you have several of them or if you are using the PRO app.
  3. Go to the Control menu.
  4. Click on the blue bell icon in the upper right corner of the screen.
  5. Select the groups for which you want to turn off the chime.
  6. Click Done in the upper right corner of the screen.

If the chime were turned off for all groups, the bell would turn white. If the chime were turned off for specific groups only, the bell would remain blue. In either case, all users will receive corresponding notifications in the Ajax app.

To turn the chime back on, click on the bell and specify the required groups. Unavailable groups will be marked in grey.

A group is unavailable if the chime’s setup is not completed for it and if a siren or an opening detector is unavailable (the device is lost connection with the hub/range extender or is temporarily disconnected).
