Walk Test Mode:
The RE – 150D provides the capability to perform a walktest of
the system without triggering the Fire Relay. Walk test Mode
allows for testing of all the zones.
For a walktest, the initiating device activated on a zone will
cause the Notification Appliance Circuits (Sounder/Hooter) to
turn on for three seconds. Any smoke detectors that are
activated will be reset automatically after 6 seconds.
Placing the control panel into Walktest Mode will be possible
only if the system has no active alarms.
After entering into the walktest mode, the fire relay contact
disablement is activated automatically and it will go back to
previous status while we are coming out from this mode.
This feature helps to perform the testing of devices by a
single person. In this mode if the panel detects any fire then
after 3 seconds the panel will get automatically silenced. After
6 seconds of silence, the panel will go to reset. This reset is
done for only that particular zone.
