| All professional quality alarm
systems are fitted with
rechargeable batteries in
order to maintain the system
in the event of a power
failure. In general you
should fit the largest
capacity battery that will fit
in the Control Panel - as a
general guide 2.1Ah batteries
are suitable for compact
control panels whereas 2.8Ah
and 7.0Ah batteries will fit
inside larger control panels
and most blank
end-stations. Battery life
is around 5 years: the
battery can be tested by
removing the mains power to
the Control Panel - if the
external sounder sounds then
the battery is past its useful
life (or there isn't one fitted). |
