Simplex 4008-9801 Expansion Power Supply Rev A

Expansion Power Supply EPS Installation Instructions 4008 4006 9801 Expansion Power Supply EPS is an option module installs into the main fire alarm control panel The EPS provides two NACs and filtered regulated 24 VDC alarm power 3 A alarm power may be split between the two NACs and the A auxiliary 24 VDC power tap Refer to the NAC ratings section of these for circuit loading restrictions The expansion power supply is to the right of the main system board MSB at the bottom of the and is connected by the installer via three separate harnesses EPS per system is allowed 1 below is an
