6.5 Detector Mounting
The detector may be mounted on a simple fabricated bracket, or preferably the
optional 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) 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 10).
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 7). Secure the detector to the Swivel Mount by
four (4) 1/4”-20UNC screws or M6 x 1P (Item 9) 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 8) 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.
