Automatic ACS door to be released but not opened on fire event (Gallagher)

[Cieska]

Hey,

 

Need to think of the wiring logic for the automatic opening mechanism door with a maglock to be released in a fire event from the Gallagher panel.

 

A few spare puzzle pieces are available in my brain:

• I want to avoid using additional relays and hanging on the cables in an already tiny panel.
• Usually, the door opening mechanism is controlled with 24v and recommended to be controlled with dry contacts, but would I be able to use a common ground in some way?
• Gallagher fire interface relay / DC distributor has some other ways to be wired in, I wonder if this can be employed to achieve this function?
• I may sacrifice additional Gallagher controller output for this, but I couldn't find a function for this, or is it a logic block's function?

 

Happy Easter.
