Hi all,
I've recently moved to a house with a automatic gate with a ACH intercom keypad and a Commax door phone inside the house.
Everything works as it should apart from calling from outside using the keypad as it wouldn't ring the phone inside.
I don't know much about intercom / automatic gate system, and want to learn through the process of fixing it myself.
It's a 4 wire system, I've tested the intercom phone by shorting the pins and it rings. Not sure if it is the broken wire or the keypad.
I want to unscrew the keypad from the wall, but the screws are some sort of tamper proof screw which I couldn't identify online.
Dose anyone know what is this screw called? and the model number of the keypad?
Can any one provide advice on intercom system will be appreciated.
