Alarm Controls PD4C – Frequently Asked Questions
1) Does the Alarm Controls PD4C power distribution module have its own transformer, or does it need a separate power supply?
The PD4C has no power source of its own. It takes the primary output from an existing AC or DC power supply and splits it into four outputs of the same voltage type, so each piece of equipment sits on its own circuit. Output voltage is whatever the supply feeds it, 12V or 24V. Order the supply separately.
2) Can I run 12V strikes and 24V maglocks off one PD4C board?
No. The PD4C passes through whatever the feeding supply puts out, so all four outputs carry the same voltage and the same current type. A mixed 12V and 24V job needs two supplies and two distribution boards, or a supply with independent dual-voltage outputs.
3) Will the PD4C fit inside my existing access control enclosure?
The board measures 2.25 inches wide by 3.75 inches high by 1 inch deep, and the mounting hole pattern is 3.44 inches by 1-7/8 inches. Check the depth clearance against your can door before you commit, since the 1 inch figure is board depth with components.
4) What fuse does the PD4C use and is the main input protected?
The main input runs through a single separate fuse for surge protection, a 3 amp glass fuse. The board also accepts standard automotive ATO sizes, so replacements are easy to source. That fuse is the total input ceiling, which is the real limit on how much load you hang off all four legs combined.
5) How do I tell which output on the PD4C has dropped out during a service call?
Every one of the four outputs carries its own status LED, so a dead leg shows at a glance without pulling a meter. There is also an on/off power switch on the board, which lets you kill the whole distribution side for service without disturbing the supply upstream.
6) Do the outputs on the PD4C switch, or are they always on?
The PD4C is a distribution board, not a control board. It divides the incoming supply output into four constant circuits of the same voltage and gives each one an LED. Switching a door on card read or REX is done by the access control panel or relay upstream, not here.
7) Is the PD4C suitable for commercial building access control work?
Yes, the PD4C is a commercial-grade power distribution module. It is the board integrators use inside a power supply enclosure to break one supply output into four fused, individually indicated circuits for strikes, maglocks, readers, or REX devices.
