How the re alarm muting function works
Using the KeyPad, you can mute the interconnected re detectors alarm by
pressing the Function button (if the corresponding setting is enabled). The
reaction of the system to pressing a button depends on the state of the system:
Interconnected FireProtect Alarms have already propagated — by the rst
press of the Function button, all sirens of the re detectors are muted,
except for those that registered the alarm. Pressing the button again mutes
the remaining detectors.
The interconnected alarms delay time lasts — by pressing the Function
button, the siren of the triggered FireProtect/FireProtect Plus detector is
muted.

Functionality Testing
The Ajax security system allows conducting tests for checking the functionality
of connected devices.
The tests do not start straight away but within a period of 36 seconds when
using the standard settings. The test time start depends on the settings of the
detector scanning period (the paragraph on "Jeweller" settings in hub settings).

Installation
Before installing the detector, make sure that you have selected the optimal location and
it is in compliance with the guidelines contained in this manual!
