MOTION DETECTOR
GENERAL INFORMATION
The Rx4GLD motion detector offers the ultimate in performance with
an unsurpassed combination of detection and false alarm immunity.
Optimal operation is assured with the following advanced features:
¥ Microprocessor-based algorithms for advanced detection & false
alarm immunity processing
¥ Ademco's patented Alternate Polarity Quad detector for
improved false alarm immunity
¥ Immune to pets and other animals up to 45 lbs.
¥ Automatic adaptation to environmental disturbances
¥ Selectable sensitivity
¥ Fast walk rate (10ft/sec)
¥ Advanced dual-slope temperature compensation
¥ Dual channel supervision that reverts to single channel operation
when a failure in the other channel is detected
¥ Form C relay and tamper
¥ Zone-locating walk-test mode
This detector includes a standard wide angle mirror (installed), and an
interchangeable long range/curtain mirror. The optional 1875PA pet
alley mirror is also available. Optional swivel mounting brackets are
available under part number 998SB and Quest-SB2.
CHANGING THE MIRROR
1. Remove front cover by inserting a screwdriver blade in the groove
between the cover and base along the bottom edge and twisting.
2. Spread either or both plastic prongs holding the wide angle
mirror, and remove the mirror. See Fig. 2 for location of prongs.
3. Insert one side of the long range/curtain mirror under a prong, and
snap the other side under the other prong. Make sure the mirror
sides are squarely in their corner rests and are held securely under
the prongs.
NOTE:
Mirror surface should be free of dirt, foreign matter and
fingerprints. Use a soft, dry cloth to wipe mirror surfaces, if
required.
MIRROR MASKING
Use the supplied masking strips to produce a protection pattern that
suits the particular requirements of the protected area, or to eliminate
coverage from areas where you anticipate environmental disturbances
that might reduce the PIR's stability (a heater or other heat-producing
object for example).
Simply peel off the appropriate pressure-sensitive strip(s) and apply
over the desired mirror segment(s). Each masked segment eliminates
one zone of protection from the coverage pattern. For convenience,
the masking material may be placed on the white filter material
covering the upper tier, instead of placing it on the mirror itself.

zone, mask the leftmost mirror segment.
COVERAGE PATTERNS
Figure 1 shows protective patterns for a nominal mounting height of
7 ft (2.1m).
Best coverage will be obtained when the mounting site is selected so
that the likely direction of the intruder is across the pattern of the
detector.
