How are the 2 relays on the FW-FSLC-DUCT (addressable duct detector) controlled?
The 2 relays on the FW-FSLC-DUCT are intended for local fan shutdown control. Upon local duct detector alarm, the relays will change state, cutting off power to the fans they are wired to control (10A at 250VAC max). The system must be silenced through code entry at the keypad followed by the pressing of the SILENCE button. Once the system is completely silenced AND the duct detector has returned to a normal state (no smoke in the chamber) the RESET button can be pressed to return the 2 duct detector relays to their normal state and reactivate the fans.
