Tumpang thread a while...

I bought a sub-sale house last year with Blueguard alarm system already installed. Currently I am not using it because there is problem with 2 sensors up in the roof, it will keep activated.

So anyone know any good and reasonable price contractor/supplier/vendor who can come to my place to service the system and solve the problem? My area is in Shah Alam.

TQ and good luck hunting your alarm system.
