Resetting smoke detectors
After an alarm condition, reset smoke detectors to exit the alarm condition.
Note: Verify with your alarm company if this function is required on your system.
To reset the sensors
1. Press and hold the Reset key on the keypad for 2 seconds. If the reset is successful, the alarm
is cancelled.
2. If a smoke detector fails to reset, it may still be detecting an alarm condition. If unsuccessful,
the alarm will reactivate or continue. Contact your alarm system provider.
Carbon monoxide alarm
WARNING: Carefully review your Carbon Monoxide Alarm Installation/User Guide to determine
the necessary actions required to ensure your safety and ensure that the equipment is operating
correctly. Incorporate the steps outlined in the guide into your evacuation plan.
Activation of your CO alarm indicates the presence of carbon monoxide (CO), which can be fatal.
During an alarm:
• The red LED on the CO detector flashes rapidly and buzzer sounds with a repeating cadence of
4 quick beeps, 5-second pause, 4 quick beeps.
• The siren connected to the control panel produces the same cadence as above.
• The keypad provides audible and visual indication of the CO alarm.
If the Carbon Monoxide Alarm Sounds
1. Immediately move outdoors or to an open door/window.
2. Call emergency services or your fire department.
Bells Silenced LCD display for CO alarms
If you silence a CO alarm by entering a user code, and the zone that initiated the CO alarm remains
open, a Bells Silenced message displays. The system automatically clears the message when all the
CO zones are restored on the system. When the Bells Silenced message displays, a user can still
view all standard base menu messages by using the manual Scroll button.
Note: The Bells Silenced message also overrides the automatic display of the Alarm Memory
feature for CO alarms.
Intrusion and burglary alarm
WARNING: If you are unsure of the source of the alarm approach with caution.
The intrusion and burglary alarm is a continuous siren. If the Intrusion alarm was accidental,
complete the following steps:
1. Enter your Access Code to silence the alarm. If the code is entered within 30s (or the
programmed value of the alarm transmission delay) the transmission of the alarm to the
monitoring station will be cancelled.
- Call your central station to avoid a dispatch.
