Silence the beeping
Press [*] to silence the beeps.
For wireless fire or CO devices with a low battery or tamper, the beeping comes back after 4 hours if the problem is still there.
See what the trouble is
Press [*][2] and follow the screen to see each trouble.
While you’re viewing troubles, the Trouble light flashes once for level 1, twice for level 2, and so on.
If the Trouble light flashes on its own, the keypad’s own battery is low.
What each trouble means
AC power failure
The panel lost power and is running on its battery for several hours. Call us.
Low battery
The panel, a wireless device or a keypad battery is low. Call us. Wireless device batteries can be replaced as the device’s instructions say.
Communication failure
The alarm can’t reach the monitoring station by phone line, cellular or internet. Call us: your alarm may not be monitored.
Zone tamper or device fault
A sensor or device has been tampered with or has failed. Call us.
