11. SYSTEM TROUBLE INDICATIONS

The DUAL 824P Control Panel is a self- monitoring supervised wireless system. If the Control Panel detects a problem with any of the supervised system sensors or with its power, it will display the appropriate trouble indication and, if monitored, report the trouble to the Central Station through the communicator (depending on communicator programming).

CONTROL PANEL POWER

The Control Panel constantly charges and monitors the optional backup battery (if installed).

The POWER indicator normally glows when AC power is on.

If the Control Panel’s power condition is abnormal, the keypad's TROUBLE indicator will light. The POWER light will indicate the type of trouble.

With a charged backup battery installed, if the Control Panel looses AC power, the POWER indicator will blink as the Control Panel runs on the backup battery.

If the backup battery is low, recharging, or not installed, the POWER indicator blinks when AC power is present.

If the AC power is off and no backup battery is installed, or the battery fuse is blown, the POWER indicator will be off (in this case, the system has no power, all indicators are dark, and the system is disabled).

Normal battery life for the type of backup battery used in the Control Panel is 3-4 years. If the battery does not take a charge in 72 hours, it should be replaced.

WIRELESS SENSOR LOW BATTERIES

If the TROUBLE indicator lights, and the BATTERIES indicator is blinking, one or more wireless sensors have a low battery.

1.Press for one second to view sensor status. The sensor status indicator for any sensor with a low battery will light along with the BATTERIES indicator.

2.Replace the wireless sensor's battery as described in its instructions.

3.Switch to Test Mode after replacing the wireless sensor battery and completely test the system (see Test Mode). Switching to Test Mode clears the trouble indication.

SENSOR RADIO TROUBLE

If the TROUBLE indicator lights, and the RADIO indicator is blinking, status reports from one or more wireless sensors have not received in eight hours.

1.Press for one second to view sensor status. The sensor status indicator for any sensor with trouble will light along with the RADIO indicator.

2.Switch to Test Mode after servicing the sensor and completely test the system (see Test Mode). Switching to Test Mode clears the trouble indication.
