24 volt supply

Its great that the 641m you can put the fire mute module on but how can i power the unit off 24v DC when there is no mains connected is there a tap point on the main board that i can connect a 24v supply to, then i can keep the system compliant.


  • Hi grunter375,

    So you want to be able to power down the 641M processor from the fire alarm?
