What is Chime, and how does this function work

How chime function works

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.

After you turn notifications on, a bell icon appears in the Control tab at the bottom of the screen. The icon shows the feature status.

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 bell icon at the bottom 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 bell icon at the bottom 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 black. 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).
