Replacing a device in alarm
You can replace a device with a new device of the same type while it is in alarm. You
may need to do this because the device is faulty or for other troubleshooting reasons.
If you replace a device while it is in alarm, the device and control panel operate as
follows:
• When the device in alarm is removed, the control panel remains in alarm and a
trouble event is displayed.
• The new device does not go into alarm when it is installed, but the LCD displays a
second trouble event when the new device is detected by the panel.
• When the control panel resolves the new device, the alarm condition restores and
the two trouble events clear on the control panel.
Note: If the device causing the alarm is reinstalled, the device goes back into alarm
and the alarm condition does not restore.
