Power Supplies
The Premier MX 2,4, 8 and 16 zone panels produce d.c. power regulation directly on
the C1627 motherboard. The Precept 32 zone panel has an off-board power supply via
a dedicated PCB (C1652) contained within the enclosure of the fire alarm panel.
For all panels, the output voltage is adjustable from 25V to 28.2V via a small trimmer
potentiometer on the PCB. As the output voltage is factory set however, this should
not be necessary.
