PGM interfacing

Hey all!

I'm putting a DSC PC1832 panel in my house, and I want to wire the PGM output to an alarm input on my DVR so if the alarm goes off, it will send a push notification to my surveillance app. Shorting across the alarm input (DI0 to GND) properly generates a trigger when set to NO operation.

I set PGM1 to option 01 ("Residential Burglary and Fire Bell Output"), and wired from AUX+ on the panel to DI0 on the DVR, and PGM1 to GND, and I get nothing. I've reversed polarity (AUX+ to GND and PGM1 to DI0), which results in a "normally closed" condition, so I changed the input to default to NC, but again, there's no change in state when triggering an alarm.

Will I need to include a relay for this? Or am I just not setting the output option for the PGM?

You may not have it properly programmed but you definitely need a relay.

I would use a 12vdc relay and connect it to the bell output of the panel.

Yes, you need the relay. If your input is expecting a dry contact input. The PGM isn't a contact closure, it's a shunt to ground.
