Linear DUAL 824 - Manual (Page 27)

✦ 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.
