Access Control Power Supplies


The HP300ULM is a 12VDC or 24VDC power supply with an HPMOM6 distribution controller to be used with Card
Access Systems. It provides 12/24VDC through 6 power-limited outputs. The 6 outputs will switch ON or OFF security
devices such as Magnetic Locks, Door Strikes, Magnetic Fire Door Holders, etc. The HPMOM6 offers a choice of two (2)
outputs, “Fail Safe or Fail Secure” and a choice of two (2) Fire inputs, N/O or N/C, and Reverse Polarity triggered by the FACP. The Controller also has 2 Trouble/Alarm dry contact outputs type “Form C”; 1) Power Fail/ PTC Activated, and 2) FACP Triggered. The unit has not been evaluated as elevator equipment, and is not authorized for bell output in
Mercantile applications.

Application Notice - This Application notice gives instruction to qualified personnel on how to configure the HP-UL series power supply to accept an AC line voltage of 230VAC at 50/60Hz. Be sure to measure ac mains output voltage before performing any conversions on power supply.
