ness Guardpost installation & Programming
Guardpost employs sophisticated power management software to
maximise main battery life and increase the time between charging.
Guardpost can be operated in FULL TIME MAINS mode, BATTERY
ONLY mode or SOLAR CELL charge mode.
In Full Time Mains Mode, Guardpost constantly trickle charges the main
battery.
Battery Only mode and Solar Cell modes are low current modes
designed to consume the minimal power by shutting down non-essential
circuits and by the use of sleep/wake cycles. See the programming
option POWER for more information.
In power conservation modes Guardpost can be operated for up to 4
months without recharging. In this case, Guardpost will initiate fast-
charging mode for 24 hours once the mains charger is connected.
The OK light will remain on during fast charging only.
LOAD TEST
A battery test is performed by briefly applying a simulated load
on power-up, every 24 hours, on disarming and 3 hours after the
completion of a recharge cycle (only if mains was on at the end of
recharge cycle, and no siren activity occurred after recharge period).
ALARMS
If a low battery is detected when mains is on, no alarm is displayed or
reported, but the battery is recharged for 24 hours.
If a low battery is detected and mains is off, a LOW < MAIN < BATTRY
alarm is displayed and reported if enabled, and the battery is recharged
for 24 hours when mains comes on. When mains comes on, the alarm
condition is immediately cleared and restored.
If a low battery is detected after the completion of a recharge cycle,
a FAULT < MAIN < BATTRY alarm is displayed and unconditionally
reported. If the battery passes a subsequent load test, this condition is
restored.
Guardpost has onboard support for power supply and charging by solar
cells.
• Solar cell power input connects to the AC red wires for the solar
connections.
• Select SLR-30, SLR-1H or SLR-2H power management mode.
• A 12V 10W-20W solar panel is recommended with max power output
of 17.6V.
Guardpost makes efficient use of available solar power by switching
between fast charge and float charge while monitoring the battery
capacity at all times.
