Re: Napco MA-3000 Fire Bell Trouble warning upon power-up.



Thank you for the reply...

I did try a 2.2K resistor across those terminals (Fire Relay common #6
and N/O #8) earlier on when I was trying several configs to eliminate
the "Fire Bell Trouble" warning. It did not make a difference. I still
get the warning.

Jumper is not yet cut---so the system will send 24VDC thru those
terminals upon a fire alarm? If there is a siren driver and speaker
connected (I have an Ademco #744 with an Emer Prod Corp # 60-20, 8
ohms-20 watt "Siren Less Driver") shouldn't that satisfy the system's
need for resistence across those terminals since a resistor wouldn't.
Incidentially is that EPC device ( labeled "Siren Less Driver" )
actually a siren and not a speaker?... I guess I'm still trying to
understand the relationship between a siren driver board (i.e. the
Ademco #744) and the device that looks like a speaker. (would the EPC
device work without the Ademco cir-board?-- I'm checking the net for
specs on that device to see if it can)

THANKS again for the advice, any follow-up or further suggestions would
be helpful.
