5 in. x 2.8 in. x 2.2 in.
(12.7 cm x 7.1 cm x 5.6 cm)
•
Input Power:
9 to 15 VDC, 22 mA DC nominal (up to
52 mA DC during walk testing, stored
alarms, or trouble conditions). Use only
an Approved Limited Power Source.
•
Standby Power:
No internal standby battery. Standby
power
must
be provided by an Approved
Limited Power Source. Twenty-two
mAh required for each hour of standby
time needed.
Four hours (88 mAh)
minimum are required for UL Listed
Requirements.
•
Alarm Relay:
Silent operating Normally Closed reed
relay. Contacts rated 3 watts, 125 mA,
28 VDC maximum for DC resistive
loads; and protected by a 4.7 ohm, 0.5
watt resistor in the common "C" leg of
the relay. To be connected to a SELV
(Safety Extra-Low Voltage) circuit only.
Do
not
use with capacitive or inductive
loads.
•
Tamper:
Normally Closed (with cover on).
Contacts rated at 28 VDC, 125 mA max.
To be connected to a SELV (Safety Extra-
Low Voltage) circuit only. Connect
tamper circuit to 24-hour protection
circuit.
•
Trouble
:
Solid State output shorts to ground (-)
when the detector is in a supervision
trouble condition. Maximum load is 25
mA, Vsat @ 10 mA = 0.5 VDC.
•
Temperature Range:
-40°F to +120°F (-40°C to +49°C).
For UL Listed requirements, the
temperature range is +32°F to +120°F
(0°C to +49°C), indoor use.
•

Installation Considerations
NOTE:
The DS970 is
not
recommended for installations containing
pets or small animals. Use the DS820 or DS835 for such
installations.
•
Never
install the detector in an environment that causes an alarm
condition in one technology. Good installations start with the LED
OFF
when there is no target motion. It should never be left to
operate with the tri-color LED in a constant or intermittent green,
yellow, or red condition.
•
Point the unit away from outside traffic (roads/alleys).
NOTE:
Microwave energy will pass through glass and most
common non-metallic construction walls.
•
Avoid installations where rotating machines (e.g. ceiling fans)
are normally in operation within the coverage pattern. Point the
unit away from glass exposed to the outdoors and objects that
may change temperature rapidly.
NOTE:
The PIR detector will react to objects rapidly changing
temperature within its field-of-view.
•
Eliminate interference from nearby outside sources.
3.0
Mounting
•
Select a location likely to intercept an intruder moving
across
the
coverage pattern. The surface should be solid and vibration-
free. Mounting height range is 6 to 8 ft. (1.8 to 2.4 m).
Recommended mounting height is 7.5 ft. (2.3 m).
•
Remove the cover. Insert a flathead screwdriver into the locking
tab hole at the bottom front of the detector. Pull the cover up and
forward.
