Sayfayı YazdırIf the unit is to be mounted higher than 9' (2.7m), perhaps as high as 12' (3.7m), or if it is desired to obtain a
range of less than 50' (15.2m) for a particular installation, the optical head may be tilted downward. Combina-
tions of mounting height and "tilt" can be used to obtain coverages asshown in Diagram 3. To adjust the tilt
of the optical head, grasp the metal casting firmly between thumb and index finger at both sides (where,a
ridge is provided); pull gently forward until the assembly is free, then set the tabs on the casting into the
desired notches on the bracket and release. See Diagram 2. IMPORTANT: Do not touch the reflector or sensor '1 :
surfaces.

Nos. 651,651=6, 65%~~EXI The pattern of protection provided by the 651 series includes six zones positioned in
a pattern which is ideal for the protection of hallways, corridors or aisles.
The pattern consists of a main zone; two intermediate zones, on either side of the main zone and angled
slightly below the main zone; and three downward zones, one aligned with and below the main zone'and two
to the outside and below the intermediate zones. See Diagrams 4 and 5.
The entire pattern may be panned left or right up to 20".
The optical system has been designed to give proper coverage based upon the typical mounting height of 1'6"
(2.3m). However, the unit may be mounted at any height between 7' (2.lm) and 9' (2.7m) to achieve the proper
100' (395m) pattern. See Diagram 5a.
If the unit is to be mounted higher than 9' (2.7m), perhaps as high as 13' (4.0m), then the full range may be ob-
tained by tilting the optical assembly forward one notch (using the method described above). This will provide
proper coverage for mounting heights between 10' (3.0m) and 13' (4.0m). See Diagram 5c. Reduced range may
be obtained, if desired, by mounting the unit higher and aiming the optical assembly fully downward. See
Diagram 5s.
"Dead" Zone Caution: Note in Diagram 3 and 5 that for several tilt position/mounting
height combinations
there are indicated "dead zones" within which a person could be moving and not be detected by any of the
unit's coverage zones. In general, these dead zones are apt to be present between the intermediate and
downward zones as the unit's mounting height is increased and its coverage pattern is tilted downward.
Selecting a Mounting Location:
Because the Nos. 650 and 651 Series Passive Infrared Detectors respond to changes in energy which occur
when an intruder moves into or out of a zone, best coverage will be obtained if the mounting site is selected
such that the likely direction of intruder motion is ACROSS the pattern. See Diagrams 6a, b and c.
In a hallway or aisle, a No. 651 series unit should be aimed directly down the center of the area; the in-
termediate zones will prevent an intruder from avoiding detection by following the wall. See Diagram 6d.
An alternate approach is to angle the main zone from "corner-to-corner". See Diagram 6e.
INSTALLATION AND WIRING:
Passive I.R. units are remarkably resistant to false alarm hazards but the following recommendations should
be observed:
Avoid locating unit where central heating radiators, quartz (or other radiant) heaters, live fires or ventilating
registers could be within the protective zones.
Avoid locating the unit in direct sunlight or directly above strong sources of heat.
Avoid locating unit on unstable surfaces.
Mounting:
IMPORTANT: Be careful during installation or adjustment NOT TO TOUCH THE REFLECTOR OR SENSOR
SURFACES. WHEN POSITIONING THE HEAD ASSEMBLY GRIP THE DIE-CAST BODY ONLY, AS SHOWN IN
DIAGRAM 2.
1. Mount the wall plate to a firm and vertical surface (flat on wall or in corner) at the recommended height (see
previous section). Orient the plate so that its unit mounting hooks are at the bottom. If wiring is provided
from a hole in the mounting surface, center the mounting plate with the bottom of the plate just above the
hole. This will aiign the wires with the wiring entry in the case when the unit is secured. See Diagram 7.

2. Remove front cover by loosening the retaining screw.
3. Push the two special hex head screws, provided, through the two retainer type mounting holes at rear of the
plastic case, if this has not already been done.
4. Attach unit to wall plate, as follows: Engage lower hooks on wall plate into case bottom (see Diagram 7)
and secure unit to wall plate with the two hex head screws provided. Note: Move detector head left or right
to gain access to screws. Do not remove detector head from unit as damage to mirror may result.
Note: For recessed mounting, the No. 659MK Flush Moun'tIng Kit is available. Follow the instructions accom-
panying it.
