Optional Power Supply Connections
The PCS250G is designed to be powered by the control panel.
However, if you want the PCS250G to function even if the control
panel battery is low, or if power failures are anticipated, an
external power supply with a backup battery (such as the PS817)
can be used. For more information on connecting to an external
power supply visit paradox.com.
Using an External Power Input
When an external power input is used as a backup power supply,
the following connections are required:
•
Screw 1 = +12V
•
Screw 2 = ground
The maximum wire length for each of those power lines is as
follows:
•
12m (40 ft.) for AWG24
•
20m (65 ft.) for AWG22
•
30m (100 ft.) for AWG20
•
50m (160 ft.) for AWG18
