Alarm maintenance - question

[RK_London]

I have an existing Risco alarm system which include 3 wireless internal detectors upgraded 4 years ago. My alarm company doesn't 't want to maintain them anymore because they are out-dated and want me to upgrade again. Can't afford that right now but need to replace the batteries ( they were replaced 2 yrs ago). Can I go to another company or am I locked into the company that installed my alarm.

Thanks for the help

Is it showing low battery ? If so and it won’t set ….you have nothing to lose by replacing them yourself …I’ve been to a couple that where installed by another and was able to change and reset with the customer code …

Nothing showing low battery - normally change them every two years. Thought I would trigger a tamper alarm if I did it myself. How did you change batteries with customer code?

Open detector ….tamper goes off ….enter code to stop ….replace battery ….reset with code

I've attached a picture of the two wireless detector types - can you help in figuring out what batteries I need

You need to do a walk test after replacing these batteries.

Users should be able to do this the alternative is to down power then panel put battery back on then mains.

you may get a tamper a little while after replacing the battteries and doing the walk test after replacing stops that from being an issue usually

Cr 123a for the pir
Not sure if it’s a Cr 2 or Cr 123a for the door sensor

CR123A for them both

if the batteries in the wireless detectors run down before I replace them, am I right in thinking the only issues is I won't be able to set the alarm.

They are one way devices, so depends if the jam the signal due to low battery.

which can occur if they don’t jam and haven’t been opened you should be able to set alarm.

How long do CR123A batteries last?

How long do CR123A batteries last?

A lot longer in rooms that are never used than they do where someone walks past the detector or opens the door every few minutes. 12 to 24 months ish.

Most domestics get two years on most brands, if you start replacing all the sensors make a note of when you replaced them, you can see when the first one flags, and use this as a guide to replace all routinely.
