The detector can be mounted directly on the wall through 7-mm hole (item 7, Fig.

The Tilt mount enables the detector to be rotated up to 60 degrees in all directions.

6.5.2 Tilt installation (Figs. No. 6 and 7)
1 Place the tilt mount (item 1) in its designated location and secure it with three
(3) fasteners through three (3) holes dia. 5.2mm (Fig. 7).Note: Skip this step if
the Tilt Mount is already installed. Also detector removal for maintenance
purpose does not require Tilt Mount removal.
2 Unpack the detector.
3 Place the detector, with its connector or cable pointing down, on the holding
plate of the tilt mount (item 2). Secure the detector by four (4) 10-32 UNF x
7/16” screws with No. 10 spring washers to the Tilt Mount. Use 5/32 Hex Key
for 10-32 screw (item 5).
4 Release the locking screw (item 4) in such a way that allows rotating the
detector. Point the detector towards the protected area and make certain that
the view of the area is unobstructed. Secure the detector in that position by
tightening the locking screws (item 4) on the tilt mount. (Make sure the detector
is in the right position.)
The detector is now correctly located, aligned and ready to be connected to the
system.
