557.202.612 PMM840 – 40 V PSU – 40V Regulated Loop Supply – Loop 3 and 4 Expansion
The PMM840 board provides extra loop power to an XLM800 loop expansion board, fitted in a Fireclass fire alarm control panel. It takes an unused 24 V feed from the existing power supply and converts this to 40 V for powering the loop. The PMM840 can provide up to 1.2 A at 40 V.
The PMM840 stacks on top of an existing PMM800 board. The PMM840 is based on the PMM800 board, but with fewer components.
