10 Powering up the SPC controller

The SPC controller has two power sources, the mains supply and the integral standby battery. A

qualified electrician should undertake connection to the mains and the mains supply should be

connected from a spur that can be isolated. See Wiring of mains cable to the controller on page276 for

full details of conductor sizes/fuse ratings, etc.

The SPC should be powered from the mains first and then the internal standby battery. For compliance

to EN only one battery should be fitted of the appropriate capacity.

After the operating voltage is applied to the alarm panel, operational readiness is achieved after 15

seconds.

10.1 Powering from battery only

It is recommended that when powering a system from battery only, the battery should be in a fully

charged state (>13.0V). The system may not power up when using a battery with less than 12V and no

mains is applied.

1. Press and hold the PSU Kickstart button (See Controller Hardware

SPC42/SPC52/SPC53/SPC63 on page31).

All PCB LEDs flash.

2. Release the PSU Kickstart button.

NOTICE: The battery will continue to power the system until deep discharge level (10.5V to 10.8V)

has been detected. The time duration that the system will hold up on battery will depend on the

external loading and Ah rating of the battery.
