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 when the device is faulty or for troubleshooting purposes. 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 displays.
• When installed, the new device does not go into alarm, but the LCD displays a second
trouble event when the panel detects the new.
• When the control panel resolves the new device, the alarm condition restores and the two
trouble events clear from the control panel.
Note: If the device causing the alarm is reinstalled, the device goes into alarm and the alarm
condition does not restore.
