Installation Instructions
for the DS935Z
ASIC-Based PIR Intrusion Detector
1.0
Specifications
•
Input Power:
9.0 VDC to 15.0 VDC
•
Current Draw:
15 mA @ 12.0 VDC
•
Standby Power:
There is no internal standby battery.
Connect to DC power sources
capable of supplying standby power
if primary power fails. For each hour
of standby time needed, 15 mAh are
required.
For UL Listed
Requirements, four hours (60 mAh)
minimum are required.
• Coverage:
Broad (standard):
35 ft. x 35 ft. (10.7 m x 10.7 m)
Barrier (optional):
35 ft. x 10 ft. (10.7 m x 3.1 m)
Long Range (optional):
70 ft. x 10 ft. (21.4 m x 3.1 m)
Pet (optional):
35 ft. x 35 ft. (10.7 m x 10.7 m)
with 70 ft. (21.4 m) long range
•
Sensitivity:
Selectable for Standard or
Intermediate.
• Alarm Relay:
Form “C” reed relay with contacts rated
at 28 VDC, 125 mA maximum for DC
resistive loads.
•
Tamper Switch:
Normally Closed (with cover in place)
tamper switch. Contacts rated at
28 VDC, 125 mA maximum.
• Trouble Output:
A solid state open collector shorts to
ground (-) when the detector is in a
trouble condition. The maximum
current load is 25 mA. Vsat @10 mA =
0.5 VDC.
•
Temperature:
The storage and operating range is
-40°F to +120°F (-40°C to +49°C).
For
UL Certificated Installations, the
temperature range is +32°F to +120°F
(0°C to +49°C).
•
Options:
B335 Low Profile Swivel Mount
Bracket, B338 Ceiling Mount Bracket,
OMB93-3* Barrier Mirror, OMLR93-3*
Long Range Mirror, OMP93-3* Pet
Mirror.
*Shipped in packages of three.
NOTE:
Misalignment of the detector when using an optional
mounting bracket may reduce range and increase dead
zones.

Knockouts
The mounting surface should be solid and vibration free.
• Select a location that is most likely to intercept an intruder moving
across the coverage pattern. The recommended mounting
height range is 6.5 ft. to 8.5 ft. (2 m to 2.6 m).
• Remove the cover. Insert a thin flathead screwdriver into the
notch at the bottom of the cover and pry up.
• Remove the circuit board by depressing the circuit board retainer
tab and lifting the board out from the enclosure. Then remove
the mirror by sliding it towards the bottom and out of its tracks.
• Open the knock-out wire entrance and route the wiring through.
3.1
Surface or Corner Mounting
• Open two holes for surface or corner mounting.
• Mark the location for the mounting screws. Use the enclosure
as a template. Pre-start the mounting screws.
• Securely attach the detector.
• Replace the circuit board/mirror unit.
• Select the Vertical Angle.
Mirror Information:
The mirror is adjustable from +1° to -18°
vertically by sliding the mirror forward or back and ±10° horizontally
by rocking the mirror side to side. To change the mirror, just pull it
out from its resting grooves.
NOTE:
Excessive handling of the mirror surfaces may lead to
performance degradation.
- The following chart will help you set the correct Vertical
Angle based on the mounting height, mirror type, and
desired range.
