hi we are a firm of electricians, got a customer who has a solinoid gas valve fed via an emergency stop button near the exit to the kitchen, its a small club. He want us to link the fire alarm via this emergency stop which is not a problem to us as we thought of just picking up the 24 volt switched supply from the sounder circuit and just adding a 24 volt relay with 240 volt rated contacts job done. However i am sure i have seen on the market but dont know where a purpose made interface box with terminals for mains in, 240 volt solinoid valve out, fire alarm switch input and an emergency stop on the front of it???? any ideas where from.
