This inexpensive alarm unit works with any primary relay having a built-in alarm circuit. If your primary relay has 2 terminals marked 'A' on it then this will definitely work with your unit. (Some primary relays have the 'A' terminals underneath the unit so you may need to remove the relay to see) Most current digital primary relays have an alarm circuit.

This unit operates on its own power (9 volt transistor radio battery---INCLUDED) and emits an ear piercing wail of a siren that can be heard throughout the house.


Think about the following things:

Why wait until the morning to find out your boiler shut down during the night and there is no hot water?

Why wait until your pipes are on the verge of freezing to try to find a boiler servicing company to come and service your boiler in the middle of winter?

Why wait for your tenants to complain that they have no heat or hot water? This device lets you know the instant the boiler shuts down on safety and the primary relay shows a red light. Who is going to see the little red light on the boiler anyway? Nobody goes to the boiler room to watch! This alarm emits an ear piercing wail that can be heard throughout the house and then some! You will know when the primary relay goes off on safety with this gadget.

SO WHY WAIT ANY LONGER TO ORDER THIS?
