Provide an IAM and a Fire Alarm Auxiliary Relay to monitor the presence of shunt trip power. Provide a shunt trip circuit breaker on the elevator equipment power circuit in the elevator equipment room.
Extend the interlock conductors from the Fire Alarm Control Panel to the new shunt trip circuit breaker. To mount additional EPO boxes at other exit doors, fo llow the instructions in ﬁMount the system on a wallﬂ on page 3.
You have two alternatives for wiring your additional EPO boxes. You can cascade the boxes so that you only wire devices to one box (see page 8), or you can wire devices directly to each EPO box (see page 10).
Note. GSST type Shunt Trip Connection Scheme with mandatory Breaker Aux contact wiring and optional coil continuity detection circuit. For all AC applications a single NO aux contact is required.
For 24V and V DC applications a single NO aux contact is required. For DC applications above V two NO aux contacts wired in series are required.

Just that is necessary. A good theme, I will participate. Together we can come to a right answer.
You are not right. I can prove it. Write to me in PM, we will talk.
In it something is also to me it seems it is excellent idea. I agree with you.
I confirm. It was and with me. Let's discuss this question. Here or in PM.
Bravo, this rather good idea is necessary just by the way
