6.5 Detector Mounting
The detector may be mounted on a simple fabricated bracket, or preferably the
optional Spectrex Swivel Mount, Model No. 20/20-003. The Swivel Mount
enables the detector to be rotated up to 40 degrees in all directions.

6.5.2 Swivel installation (Figure 4a and 4b)
1 Place the swivel mount (Item 6, Fig. 4a) in its designated location and secure
it with four (4) M6 or 1/4” screws, placed 3.0 in. (76.2 mm.) apart on swivel
mount plate (Item 6, Fig. 4b).
Note
: Skip this step if the Swivel Mount is already installed. Also detector
removal for maintenance purpose does not require Swivel Mount removal.
2 Unpack the detector carefully
3 Place the detector with its conduit inlets pointing down on the holding plate
of the Swivel Mount (Item 3, Fig 4b). Secure the detector to the Swivel
Mount by four (4) 1/4”-20UNC screws or M6 x 1P (Item 5, Fig 4a) with 1/4”
(M6) spring washers enclosed with the Swivel Mount Kit.
Use 3/16 Hex Key for 1/4” screws or No. 5 Hex Key for M6 screws.
4 Tighten the three locking 3/8"-24UNF screws (item 4, Fig 4b) of the swivel
mount ring until the friction in the ball joint holds the detector in its position,
maintaining the ability to be moved by hand-applied force (Use 3/16" HEX
KEY).
5 Point the detector towards the protected area and make certain that the view
of the area is not obstructed. Secure the detector in that position by
tightening the locking screws of the swivel mount ring.
The detector is now correctly located and aligned, and ready for connecting to
the system.
