Magnetic door

[alto3]

Hi,

Can anyone please help me? I have a 120 volt smoke system and the job calls for fire doors to close when the smokes go off. It's in a 4 story residential building and they are joining to top floor condos. I will be interconnecting the two existing smoke systems.

Thanks, Tom

Normally done thru the fire panel and magnetic door holders.
Are your 120V smokes single station smoke detectors that are interconnected? If so, Firex makes a aux relay that is intended to work with the interconnect, but may not meet UL listing.
I would suggested a call to the building or fire offical.
