Honeywell IS2535 Too Old?

Konnected Alarm Panels
1

My house is about 13 years old and I disconnected my original system and wired the Konnect board in. The three door sensors work fine but I am having issues with the two Honeywell IS2535 PIR motion sensors. Are these compatible with this system?

Inside the PIR I removed the resistor (gold/red/black/red) and one started working but it goes off randomly with no motion. The other lights up but is not triggered on the Konnect. I moved it to different wiring spots on the Konnect but still does not register motion.

Konnect sells the Honeywell IS3035. Would it be worth buying and replacing them?

Suggestions?

app v3.1.5 / fw v3.0.0

Hi. I don’t see why they wouldn’t work, but as you mentioned, they are old. Maybe just use this as an opportunity to replace them with something like this.

I checked the installation instructions seems like a standard PIR, have you tested the supply voltage at the sensor? Do you have a multimeter to make sure that it is switching the contacts when triggered on the one that does nothing?

They should work. Doubt that they’re “too old”.
Can you post a pic of the wiring terminals inside the sensor?
