LASER HAZARD
The detector in the enclosure is a factory-sealed unit
containing a Class-3B laser product with invisible
radiation.
AVOID EXPOSURE TO BEAM
Extended exposure to a Class-3B laser directly or indirectly
may cause severe damage to the human eye.
The Detector is designed for surface mounting. It is also capable of being mounted in different
orientations to meet with the requirements of different applications. The Detector can be mounted
normally with the inlet pipe at the top of the unit. Alternatively the Detector can be mounted upside down
or recessed into the wall. The Detector incorporates conduit knockouts (concentric 0.5 inch and 0.75
inch) two each on the top, bottom, and rear.
The assembly should be mounted in a manner to minimise the number of 90 degree bends needed to
connect the Detector to the piping network. The system drawings should accurately depict the Detector
location and all piping distances and bends required for the connection to the unit. The Detector provides
an exhaust port to which can be either positioned at the side or by an optional rear exhaust port. An
exhaust port adapter can be attached. If the air must be returned from the Detector to the protected
space, then an optional adapter fits into the Detector’s exhaust port and provides a connection to a 1.0
inch threaded pipe.
The Detector is designed with 4-corner mounting holes. Installation must be in accordance with good
electrical and safety practices, although 0.25 inch mounting hardware is recommended. To mount the
assembly proceed as follows:
(1) Remove the Detector from its carton and carry out a visual inspection of the unit to
ensure that no damage has occurred during transit.
(2) Remove the lid of the Detector by turning each of the two locking screws, situated on the
bottom side of the Detector, a quarter turn anti-clockwise and lift the lid clear. Exercise
care during this procedure, as at this point the lid is still connected to the Detector.
(3) Unplug the plastic tether attached between the Detector and the lid.
(4) Unplug the status LED harness connection from the termination board, the lid is now
detached from the Detector
(5) Place the Detector in the selected location ensuring it is in the correct orientation (Display
Module reads correctly). Mark and drill the wall with the appropriate hardware and
secure into position.
