I currently have a Safewatch Pro monitored fire/security system from ADT. I have an ESL 240-COe carbon monoxide detector tied into my system. The detector started to chirp about every 5 minutes and the green led flashes every 1-2 seconds which I believe indicates the end of the sensor life. My question is since the detector is existing can I just purchase a new one and replace the old one or do I have to have a technician come to my house to swap it out?

It's just a straight device swap out; there's no intelligence in these devices. Swap away.

Just unplug the phone from the alarm in case you short the alarm wires while you are handling them.

Thats what I thought. Just wanted a little assurance.


Thank you :D

Got the detector today. Besides disconnecting the phone line from the panel while I swap out the detector should I be concerned about which order to remove the existing wires and which order to rewire the new detector?

Thank you in advance.

Out of habit, when connecting 4-wire devices like this, I usually connect the power negative last, but that's just a leftover habit from working on higher powered DC systems, like electric cranes.

There's not really any special order, though.
