10 ReadySET Aspirating Smoke Detection System Installers Handbook
Note: The PCB is fixed in place with 5 M3 x 6 screws. The detector should not be operated with any
of the screws missing, as this could cause air leaks and unreliable operation.
(5) Power supply connection terminals
(6) Volt-free relay contact terminals
(7) Configuration DIP switch: Used to configure user-selectable detector functions.
(8) Input switch terminals
(9) Optional communication terminals: used when the optional communication card is fitted to connect
the RS-485 network
(10) Detector head ribbon connector: If this lead is broken or not connected, the detector will indicate a
HEAD Fault.
(11) Detector head assembly: No user-serviceable parts. Do not remove this from the detector, due to the
risk of exposure to the laser.
(12) Detector head cover plate: This protects the laser head. The plate should not be removed from the
detector.
(13) Replaceable dust separator: This simply slides in and out of its mounting. The separator and its
replacement have IN written in red on one side, and OUT on the other to indicate correct orientation.
(14) Three mounting holes to mount the detector. Use #10-24 pan-head screws for mounting.
Note: Ensure that the detector is fixed to a flat surface so that the enclosure will not twist and
become damaged.
