About this detail

Connections between a signature controller, a SIGA-CR module, an MR-101/C relay, and multiple smoke fire dampers. The SIGA-CR module includes terminal blocks TB1 and TB2, data in and data out lines, along with a red LED for alarm/active status and a green LED for normal operation. The MR-101/C relay provides ten amp Form C contacts and connects to a twenty-four volt supply, a one hundred twenty volt connection, and the normally closed contacts of the control circuit. Smoke fire dampers are wired in series to the relay contacts and the control module.
