Wiring Harness (P/N 61-6671-XX)
The wiring harness provides an easy method for wiring to the 45FS1/45UVFS1 scanner when
remote communications are required and the distance from scanner to amplifier exceeds 200 feet.
With remote communications greater than 200 feet
, it is necessary to run the two wires used for
communications in a “multi-drop” wiring configuration. Do not directly run the communication
wires back to the flame amplifier. To assist in a “Multi-drop” wiring arrangement, Fireye offers a
wiring harness available in several lengths. The harness has a female quick disconnect to plug into
the quick disconnect on the scanner. The other end has a conduit box with a twenty (20) connector
terminal strip. Eight (8) connectors are pre-wired to the female quick disconnect. The remaining
twelve (12) connectors are used for wiring the Fireye 6 conductor cable (59-470) back to the flame
amplifier (for +24 VDC Power, Shutter, Common, Flame Signal, Remote File Select 1 & 2), and
multi-drop the 2 conductor Belden cable (22 AWG, #8761) between scanners.
The terminal strip uses push-type cage clamp connectors. Use a small screwdriver or similar device
to depress the slot beside the connector to open the connector and then insert the wire. Remove the
screwdriver to secure the wire. The connector will accept up to 14 gauge wire.
