The battery pack will automatically switch into
operation once the incoming 24V DC power
rail drops below 22V.
The Mains power LED will be on when the unit
is operating from 110/230V AC. In this mode
the battery backup module is inactive and
being charged if required. The LED’s will
indicate the charge level as the battery is
being re-charged.
If the Mains power LED is off, then the battery
pack is active and providing backup power to
the TOCSIN 700 controller and associated
detectors. In this mode of operation the charge
level indicator LED’s indicate remaining
battery power.
Once battery power drops below 20V DC the
controller determines that the battery pack is
exhausted and power to the TOCSIN 700
controller will be turned off.
As soon as mains power is restored the
controller will start re-charging the battery
pack. The charge status will be indicated on
the charge LED’s. Typical re-charge time from
flat will be approximately 5 hours.
Note that the status LED’s take up to one
minute to show correct status.
Both LED’s will flash at start up as the
controller makes an assessment of the
battery and mains power status.
