Note: These are a '10 year' model, and all have a 'Date of Replacement' = 13/06/2021.



They are used, but are in good clean condition and working fine (just removed today). So if anyone can get a couple more years use from them I'd rather that than recycle them now, hence Free.



Worked well (I think these were a Consumer Magazine best buy at the time) - no false alarms, but obviously that depends how/where you install them too.



Model: OM588H-LL


Takes a 9v battery (PP3), no batteries included.


Mounts and screws included (no rawl plugs)



Free - just cover postage. Preference to anyone who wants all 3.
