Specification for the Control panel
Specification for control panel's Power supply
The control panel consists of single board containing both the control and indicating equipment and the power
supply. A 50VA mains transformer provides a low voltage (30Vac) supply into the power supply circuits. The on
board power supply circuits produce a regulated 24V dc supply, a 24V sounder supply and a battery charger
output.
Note the control and monitoring of the power supply unit is under direct control of the microprocessor of the
control and indicating equipment.
