5.2 Recharging battery pack
It is recommended to have a spare battery pack in order not to have any sensor down time.
Normally it take about 2-3 hours to completely charge the battery. It is up to the user to
determine how many spare batteries would be needed for a given number of detectors installed
in the facility.
The wireless detector monitors the battery voltage / level. When battery is low the
detector will send the low battery signal to the main controller. The low battery icon on
the control panel is displayed. At this time the battery should be recharged. ** Do not
run the sensor on low battery for long time as it effects the life of the battery.
Power Down the sensor. Loosen the thumb screws on the transmitter board and move
the board away from the battery. You may disconnect the ribbon cable connector to
completely remove the transmitter board.
** Do not remove the screws from the panel. ***
Remove the battery holding plate and carefully remove the battery from the battery
holder. Simply pull the battery from the housing. DO NOT wiggle the battery to remove.
A wall mount battery charger is required to charge the battery pack. Insert the charger
jack into the receptacle on the lower side of the power pack assembly. See figure 3.
3 LED status indicators are provided on the bottom of the battery pack. The function of
these LEDs are explained in table below.
When the green LED is completely off then the battery is completely charged and ready
for use.

For longer battery life, the battery must not be used for long time once the low battery is
detected. The wireless sensor indicates with the battery is at low level. Batteries should be
recharged at this stage. The nominal battery charge time is approximately 2 – 3 hours
