2.0 Installation Considerations

NOTE: The DS860 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.

• Remove the circuit board from the base. Loosen the Vertical
Adjust Screw and slide the circuit board down, then out.

• Break away the appropriate thin-wall wire entrance and
mounting hole coverings in the base.

• Using the base as a template and aligning it so that the
detector will be mounted with the terminal block at the top and
the PIR lens at the bottom, mark the location of the mounting
holes on the mounting surface. Pre-start the mounting screws.

• Route wiring as necessary. Route to the rear of the base and
through the wire entrance. Make sure all wiring is unpowered

before routing.

• Securely attach the base to the mounting surface.

• Return the circuit board to the base and tighten the Vertical
Adjust Screw.

4.0 Wiring

Only apply power after all connections have been
made and inspected. Do not coil excess wiring

• Terminals 1 (–) & 2 (+): Voltage limits are 9 to 15 VDC. Use no
smaller than #22 AWG (0.8 mm) wire pair between the detector
and the power source.

• Terminals 3 & 4: Alarm relay (reed) contacts rated 3 watts,
125 mA, 28 VDC maximum for DC resistive loads and
protected by a 4.7 ohm, 0.5 watt resistor.

NOTE: Do not use with capacitive or inductive loads.

• Terminals 5 and 8: Spare.

• Terminals 6 & 7: Tamper contacts rated at 28 VDC, 125 mA.

NOTE: Plug the wire entrance hole with the foam plug provided

after all wiring connections have been made.

5.0 LED Operation

The detector uses a tri-color LED to indicate the various alarm and
supervision trouble conditions that may exist. See chart below.

LED Cause

Steady red Unit alarm
Steady yellow
Steady green PIR activation (walk test)
Flashing red
Flashing red (4 pulse sequence) Replace Unit

If the detector experiences a Microwave or PIR
self-test failure, it is in need of replacement.

NOTE: During walk testing, the LED will light for the first

technology (microwave or PIR) and then light red to
indicate a detector alarm. The LED will not indicate
activation of the second technology by lighting its color.

6.0 Feature Selection

6.1 LED On/Off Pins

The ON position allows operation of the tri-color LED. If LED
indication is not desired after setup and walk tests are completed,
place in the OFF position. The OFF position does not prevent the
LED from indicating supervision trouble conditions.

marked STD for Standard or INT for
Intermediate mode.

• Standard Sensitivity: The recommended setting for maximum
false alarm immunity. Tolerates environmental extremes on
this setting.

• Intermediate Sensitivity: The recommended setting for any
location where an intruder is expected to cover only a small
portion of the protected area. Tolerates normal environments
on this setting. This setting will improve your intruder catch
performance.

• Place the LED plug in the ON position and replace the cover.

7.1 Establishing PIR Pattern Coverage

• Turn the Microwave range adjust to minimum.

• Replace the cover and snap it into place. This will close the
tamper switch.

• Wait two minutes minimum after applying power to start walk
tests.

NOTE: During the warm-up period, the tri-color LED will flash red

until the unit has stabilized (approximately 1 to 2 minutes)
and has seen no movement for two seconds. When the
tri-color LED stops flashing, the detector is ready to be
tested. With no motion in the protection area, the tri-color
LED should be OFF. If the LED is on, re-check the
protection area for disturbances affecting the microwave
or PIR technologies.

• Walk test across the pattern at its farthest edge, then several
times closer to the detector. Start walking from outside of the
intended protection area, and observe the tri-color LED. The
edge of the pattern is determined by the first green, PIR
activation of the LED (or the first red activation if the yellow
microwave LED activates first).

• Walk test from the opposite direction to determine both
boundaries. The center of the pattern should be pointed
toward the center of the intended protection area.

NOTE: The pattern may be moved ±10° horizontally by rotating the

lens window left or right.

• Slowly bring your arm up and into the pattern to mark the lower
boundary on PIR alarm. Perform this task at 10 to 20 ft. (3 to 6
m) from the unit. Repeat from above for the upper boundary.
The center of the pattern should not be tilted upward.
