CM720B 1-Amp LAN Power Supply
1 Amp continuous rated; LAN monitored
Multiple protected power outputs
Resettable fuse protected
Pulse battery charger
AC Fail output, low battery output and low battery
The CM720B LAN Power Supply is a high efficiency
13.8V DC, 1Amp continuous rated switch mode power
supply with built-in Pulse battery charger, suitable for
charging up to 7Ah sealed lead batteries. Multiple
power outputs are provided to simplify wiring to
ancillary equipment and are protected with a selfresetting fuse.
As the CM720 is a LAN device, it can also be mounted
in its own enclosure away from the Solution 144 panel,
while still remaining fully supervised. A monitored
cabinet tamper input is provided for added security
when this connection method is used. The CM720
mounts in a single module space within the enclosure.
Two fully protected open collector outputs with LED
indicators are also provided on board for AC Fail and
Low Battery conditions.

Power Requirements
Once connected to the Solution 144 via the RS485
encrypted panel LAN, the Solution 144 panel
continuously monitors all functions of the power
supply including AC Power Fail, Low Battery, Output
Voltage, Overload conditions and even its own
temperature. Should any problems be detected, the
system will display a trouble message on the code
pad, as well as report the event to the monitoring
station so they can take appropriate action.
