james.wilson Posted August 4, 2020 Posted August 4, 2020 i would think you would need a t-relay but yes unless you have overloaded it already Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
BaconAndCabbage Posted August 4, 2020 Author Posted August 4, 2020 I was hoping to avoid increasing complexity by adding a relay. All I need a 12v and 0v signal, What I wanted to do was put say a 4.7k resistor across it and 12V. That way I'd get 12V at the PGM pin when it was "off" and 0v when it was on. The issue of course is that it doesn't seem to ever turn off. Quote

If you cant read it with a dvm then a t relay wont help Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

BaconAndCabbage Posted August 6, 2020 Author Posted August 6, 2020 Adding a resistor is far easier than adding a power burning, heating up relay. However I'm wondering does it need something like a relay to draw more current so it can turn the pin off. I'm going to try and locate a relay and I'll report back. 1 Quote
sixwheeledbeast Posted August 6, 2020 Posted August 6, 2020 "power burning, heating up relay"? A pull up resistor would dissipate the wattage across it as heat. Either way I think we are getting off topic you can test this with a meter it wouldn't need a load. If it's not switching then it's either not programmed correctly or blown. The reason it's common practice for installers use relays is for separation with any auxiliary device. Quote

Qfa Also the output maybe open without a pull up or down it won't show much logic wise Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
