Certified according to requirements of UL,
CSA, IEC and EN
Four 24 VDC outputs available
1200 mA maximum current available
Ability to power up to 64 channels of GP5
detectors
Front panel output indicator
Plugs into standard NEMA size card rack
Front panel fused 1.2A

The MPS4 Regulated Power Supply provides a consistent 24 VDC to the card rack and is
independent of the load current (unlike unregulated supplies). The regulated +24 VDC output can be
monitored for failure using NEMA TS -1 equipment. This is advantageous when using NEMA TS -1 solid state output detectors, which will not provide a call output when power is lost. The MPS4 module has four +24 VDC outputs. This allows the MPS4 to plug-in to card racks wired for multiple channel
power supplies and distributes the total 1200 mA of current to the channels connected.
The MPS4 has the ability to power up to 64 channels of PEEK/Sarasota Group 5 multi-channel
detectors.
