Parts for Home Alarm System

[sonofbullet]

Please help... I have a 20 year old Alarm System with an internal beam for detecting intruders. However, whilst having work done to my house, the glass eye-ball 2-core reflector (mushroom shape) has gone missing. Unfortunately, I do not know the model no. - does anyone know where may stock such spare parts ??

I'd have thought an alarm shop would be a good place to start!

yellow pages, or google the parts you do have
most people would use parts from a mfrs range so find one ... find all

if it's 20 years old ... don't hold your breath
