CB11 control box Intercom release button not working
#1
Hi
Have automated gates, liftmaster motors and a CB11 control box wiht two photocells on gate posts.

SRS keypad intercom with SRS phones in the house.

Exit buttons on entry phones in the house have stopped working. Removed cover and tried to touch the cables together to open gates to bypass phone incase it was local to the main handset. No joy. Looked at control panel - green light on and two lights slowly flashing as per normal. Replaced SRS intercom keypad, no joy. Not sure where to go next ?

Any pointers appreciated.
