Elk M1 and Applied Digital Secu-16
Posted by cadamo on 06/14/2010 10:01 PM

Hi there, I have a couple of PIRs that I want to connect both to a Secu16-i and an Elk-M1 Gold alarm central. A Secu16-i is a module produced by Applied digital that reads digital dry contacts much like the M1. Both require a 1K ohm resistor between the contact and the ground, so everything seems to be OK in regards to that. Is it a bad idea to connect both (secu-16 and M1) to the same PIR? I am not much of a hardware guy and I don't want to end up frying any of the modules because I am wiring them together. Thank you in advanced!

That's not a good idea. You could fry the Elk-M1G and/or the Secu16. A better idea would be to wire the PIR to an input on the Elk-M1G, then use an output on the Elk-M1G to link to the input on the Secu16. Then create a rule that causes the output to turn on and off with the state of the PIR.

Thanks. I thought so. What you mention was my second (and most expensive!) option. Thank you again!

That takes some extra ports on the M1G or the SECU-16i and ports aren't cheap; there is a cheaper option if you can suffer the loss of supervision for the PIR. Wire the PIR to power a couple of relays; each relay connected to a port on the M1G and SECU-16i. The best way to do this if possible to maintain some level of supervision is with the relay n/c; unfortunately it does waste power and not all PIRs can do that anyway.
