Comfort monitors AC Power Failure and Low Battery If there is a Power Failure on Comfort's mains power supply with the Battery Backup connected, after 60 seconds the Power Failure alarm is reported. The Keypad AC (Red) LED turns on steady to indicate power failure. The Power Failure Alarm Type is activated, which can cause a dial out to the enabled phone numbers for this alarm type. The power failure is reported in the Event Log. During a power failure, Comfort switches to the Backup Battery to continue supplying power. When there is a prolonged power failure, the Low Battery alarm will be activated. Comfort reports a Battery Warning alarm if the backup battery voltage is low (11.0 to 11.5 volts). Usually this is detected only during a Battery Test (F3,1) or the Scheduled Daily Battery Test (Configuration> Modules & Settings > Misc Settings). Comfort switches off the AC power to the system during the battery test, and if the battery voltage is low, it switches on the AC again. Hence the system will report Battery Warning Restore after Battery Warning Alarm. The Low Battery Alarm Type can be programmed to dial out to the enabled phones for this alarm type. To check the battery voltage, see this topic http://www.comfortforums.com/forum16/896.html The keypad red AC LED will blink when there is low battery (it is steady on during Power Failure) Slaves will also report their own battery warning alarm if their battery is low. This will be reported as Battery Warning Slave 1, 2 or 3 on the keypad and event log. If the setting Comfigurator > Modules & Settings > Configuration Flags > Detect Battery Disconnected is checked, then Comfort reports a Battery Warning alarm when there is no battery connected in the main Comfort or Slave modules. If this setting is disabled, Comfort detects low battery condition but not Battery Disconnected
