How To Wire A Fire Alarm Contact To A Unison Dimming Rack


This is not UL listed and will not be approved by local code if adhering to UL Emergency Lighting standards. 


I would like to use my fire alarm system to trigger circuits to full in my DR rack. Where can I land my fire alarm contact?


On the right-hand side of the DR rack, a PCB with a header (J14) for "Emergency Option" may be used for a fire alarm contact.  The dip switches (S1, S2, and S3) may be used to configure which circuits turn on when the contact is activated.
