Universal Security Instruments Relay Module for Smoke and Fire Alarms, Model USI-960

I used this to interface my hard wired smoke and CO systems to a home automation setup, works great.

Does exactly what it is supposed to do. Even better, I cut apart the heatshrink covering the module and discovered that the relay is actually a DPDT relay where only 1 of the poles was being used. I attached wires to the other relay contacts to enable an IoT computer to detect when the smoke alarms are going off. Just what I needed!

Great little device. I'm using it to trigger a Z-Wave sensor and send notification to my SmartThings hub in case of fire alarm. Tested it a few times, seems to be working OK. Hope there is never a real situation when it triggers.

Used this to add my 4 in 1 detectors to the Samsung SmartThings hub with a Ecolink door/window sensor as the input device. Easy to add inline with detectors.

Works great added to a smoke alarm system and then paired it to SmartThings.

This device is required to enable a Universal Security Instruments 5304 smoke detector to operate auxiliary devices. It is easy to install and operates as it supposed to.

I was having problem setting off an alarm panel using universal 110 volt smoke detectors. This relay took care of the problem. In addition to smoke detectors going off, it now triggers the alarm panel as well.

This unit lets me receive alarms from my smoke detectors on my home alarm system which then connects to my smart phone. Only problem is that it doesn't function when the AC power is out. No battery backup. But the smoke detectors still sound on battery power - just no remote alerts.
