Alarm Output Wiring.
LOW BATTERY & AC FAIL ALARMS.
Outputs are provided on the Power Supply for indication of Low Battery (i.e. Below
11 Volts) & AC Fail conditions. End-of-Line Resistors are already fitted on the Power Supply PCB. The outputs are wired
directly to Zone Inputs on Concept Modules as shown, and programmed appropriately.
NOTE: This wiring is not required if the Power Supply is connected to the Mini Expander via Ribbon cable, P/No: 605049 or
605050. When connected in this way, Zones 7 & 8 on the Mini Expander are connected internally to the AC fail and Low
Battery inputs and cannot be used as general purpose Zone Inputs.

Power Supply Control Wiring
The Power Supply can be configured to allow external control of the Power Supply Regulator. When the PSDOWN input is shorted
to 0 volts the Power Supply Regulator will be disabled. This will cause the Power Supply unit to run on the Battery if present. If the
Battery level drops below 11 volts, LBATT will go into alarm.
A typical application could be Battery testing. Using any Auxiliary output from a Concept module, connect the output to PSDOWN
as shown below. When the Auxiliary is turned OFF the power supply is enabled; When the Auxiliary is turned ON the power supply
is operating from its battery only. (NOTE: This is the reverse of earlier versions with JP2 selection pins fitted)
