Installation
Reference Figures 11 through 17 for installation, align-
ment, and maintenance.
WARNING
Disconnect the power from the initiating device circuits be-
fore installing the detectors.
1. The clear protective film and warning label on the
smoked lens of both the receiver and transmitter MUST
be removed before they can operate. To remove them,
grasp a free corner of the clear protective film and pull
so that both the film and the warning label are peeled
from the smoked glass lens.
2. Mount brackets and connect cables properly as detailed
above. (In any applications where the BMB Beam
Mounting Bracket kit is used, the kit should be installed
before the detector is mounted. Instructions for mount-
ing the BMB are included in the BMB kit.)
3. Insert the flange of the detector mounting bracket into
the keyed hole of the wall or ceiling mounting bracket.
Slide the detector forward into position. The detector
should now hang from the bracket.
4. Insert the correct screw and washer combination (either
wall or ceiling mount) through the slot and into the hole
of the mounting bracket flange. Tighten the screw until
almost snug. The detector should still turn easily in both
directions.
5. Open the sliding access door on the back of the unit.
6. Plug cable connector into slot in metal barrier, observing
proper orientation (see Figures 14 and 15).
7. Repeat for the other unit.

IMPORTANT:
If the detector spacing is between 30 and
60 feet, the additional filter (included) must be attached
to the receiver lens. Peel the protective backing off the
filter and install as shown in Figure 11.
