2.0 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.
- Instructions for circuit board removal, breaking away wire entrances, marking mounting holes, routing wiring, securing base, and re-inserting circuit board.
4.0 Wiring
CAUTION: Only apply power after all connections have been made and inspected. Do not coil excess wiring inside detector.
NOTE: Input power must use only an Approved Limited Power Source. Alarm and Tamper Contacts to be connected to a SELV (Safety Extra-Low Voltage) circuit only.
- 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, & 5: Alarm relay (reed) contacts rated 3 watts, 125 mA, 28 VDC maximum for DC resistive loads and protected by a 4.7 ohm, 1½ watt resistor in the common "C" leg of the relay. Use Terminals 4 & 5 for Normally Closed circuits.
- NOTE: Do not use with capacitive or inductive loads.
- Terminals 6 & 7: Tamper contacts rated at 28 VDC, 125 mA.
- Terminal 8: Memory. Refer to Section 6.0 Feature Selection.
- Terminal 9: Trouble. Solid State output.
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 | Microwave activation (walk test) |
| Steady green | PIR activation (walk test) |
| Flashing red | Warm-up period after power-up |
| Flashing red (2 pulse sequence) | Motion monitor time-out |
| Flashing red (3 pulse sequence) | Anti-mask detection |
| Flashing red (4 pulse sequence) | MW or PIR self-test failure |
Flashing red 2 - 4 = The LED flashes 2-4 times a cycle.
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.
6.2 Memory Operation and Microwave Inhibit
- To use the alarm memory function, cut the Memory Jumper (after walk testing). When this jumper is cut, the Microwave Inhibit function is also activated. This eliminates microwave transmissions during disarmed periods.
- To supply voltage, connect a switch between Terminals 2 and 8 on the detector's T-strip.
- Note: If switched voltage (between 9 and 15 V) is supplied from another source, such as an alarm panel, then wiring must also be provided from Terminal 1 of the detector to the negative (-) side of the alternate source.
- When voltage is applied to Terminal 8, any stored alarm is cleared from memory and it is ready to store the next alarm.
- When voltage is removed from Terminal 8 (disarmed condition), the tri-color LED is enabled, and a stored alarm will cause the tri-color LED to turn ON red continuously. If there is no stored alarm, the tri-color LED and relay will respond to PIR only; they will activate only during a present alarm.
- NOTE: The Motion Monitor and Anti-Mask pins must be in the OFF position in order for the Microwave Inhibit feature to work.
6.3 PIR Sensitivity Selection Pins
For selection, place the plug across the pins 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.
6.4 Motion Monitor/Anti-Mask Pins
By enabling Motion Monitor and the Anti-Mask feature with the selection pins, a choice of Off or 1 day or 30 days may be chosen for Motion Monitor.
IMPORTANT: If 1-day Motion Monitor is selected, the memory feature must be enabled by cutting the memory jumper. The Motion monitor timer will be suspended when the detector is in night (armed) mode.
6.5 Trouble Memory
Short the Trouble Memory contacts with a flathead screwdriver. The LED will indicate the last trouble condition that occurred.
7.0 Setup and Walk Tests
Select the vertical starting angle from this chart (table for DS970 Mounting Height vs. Vertical Angle for Standard Broad Lens and Long Range Lens).
To adjust the vertical starting angle for the desired mounting height and range, loosen the vertical adjust screw and slide the board up, to point the angle down. Note the settings on the vertical adjust scale.
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.
- NOTE: If desired coverage cannot be achieved, try angling the coverage pattern up or down to assure the pattern is not aimed too high or low. The angle of the PIR pattern may be vertically positioned between -10° and +2° by loosening the Vertical Adjust screw and sliding the circuit board up or down. Moving the board up will angle the pattern downward.
- Tighten the screw snug when positioning is completed.
7.2 Establishing Microwave Coverage
NOTE: It is important to wait one minute after removing/replacing the cover so the microwave portion of the detector can settle, and to wait at least ten seconds between the following walk testing procedures.
- The tri-color LED should be OFF before walk testing.
- Walk test across the pattern at the intended coverage's farthest end. Start walking from outside the intended protection area and observe the tri-color LED. The edge of the microwave pattern is determined by the first yellow, microwave activation of the LED (or the first red activation if the green PIR LED activates first).
- If adequate range can not be reached, increase the Microwave Range Adjust slightly. Continue walk testing (waiting one minute after removing/replacing the cover) and adjusting the range until the farthest edge of desired coverage has been accurately placed.
- NOTE: Do not adjust the microwave range higher than required. Doing so will enable the detector to catch movement outside of the intended coverage pattern.
- Walk test the unit from all directions to determine all the Microwave pattern boundaries. Wait at least ten seconds between walk tests.
7.3 Establishing Detector Coverage
- The tri-color LED should be OFF before walk testing.
- Walk test the unit from all directions to determine the detection boundaries. A detector alarm is signaled by the first red activation of the tri-color LED after an initial green or yellow activation.
8.0 Meter Tests
A 20,000 Ohm/Volt (or greater) analog DC VOM is recommended. Set the meter scale for 5 VDC (Use of the TC6000 is recommended, but is not essential for meter use. Either outside connector pin of the TC6000 may be used for common).
8.1 PIR Meter Readings
- Connect the meter to the PIR Noise Voltage Pins.
- With no target motion in the pattern, read the voltage.
- NOTE: The base reference level for PIR background noise is approximately 1.0 VDC. Installations in quiet environments, therefore, should result in a steady meter reading between 0.9 and 1.1 VDC.
- Walk test across the farthest edge of the coverage pattern. Make sure the detector's cover is on.
- NOTE: Voltage changes greater than +0.75 VDC from the reference level during walk tests are desirable. If changes are less than 0.75 VDC, the detector may fail to respond at this far of a distance if the temperature difference between the intruder and the background is minimal. Try adjusting the unit up and down to maximize the voltage change during walk tests.
8.2 Microwave Meter Readings
- Connect the meter to the Microwave (µw) Noise Voltage Pins.
- With no target motion in the pattern, read the voltage. The background noise voltage should be steady, and should not exceed 0.75 VDC. If it does, the cause of the disturbance should be found and eliminated.
- NOTE: Remember that microwaves penetrate non-metallic surfaces. Movement on the other side of walls and doors viewed by the detector could cause unexpected background noise readings.
9.0 Supervision Features
The supervision features function as follows:
- PIR/Microwave: The complete circuit operation of these subsystems is checked approximately every 12 hours. If the PIR or MW subsystem fails, the tri-color LED will flash red 4 times per cycle and the unit should be replaced.
- Default: If the microwave subsystem fails, the detector will default to PIR technology protection. The PIR signal sensitivity will automatically change from INT to STD.
- Trouble Clear: An intrusion alarm will reset most existing supervision trouble conditions. There must be at least 10 seconds of no activity (no alarm) prior to the detector alarm. Self Test failures will not be cleared; the detector must be replaced.
- Anti-masking: When enabled, the detector will indicate an Anti-mask supervision trouble condition if a microwave reflective material (e.g. metal, most plastics, etc.) is placed within one foot of the detector. This feature can be used to prevent intentional and accidental masking of the face of the detector. It is enabled or disabled using the Motion Monitor and Anti-mask Pins.
- NOTE: The anti-masking feature may interpret removal and/or replacement of the cover as an attempt to mask the detector and may signal a supervision trouble condition. If this should occur, reset the detector by removing and then re-applying its power. The trouble condition will also be reset by the next detector alarm after a 10 second period of no alarms from either technology.
- Motion Monitor Supervision: This feature verifies that each technology has a clear view of the detection area. When selected, a supervision timer is activated which gives the detector the ability to indicate a supervision trouble condition if the time selected by the pins has elapsed since the last detector alarm.
- If the detector does not see a detector alarm within the selected time period, the tri-color LED will flash red 2 times to indicate a supervision trouble condition and the Trouble output will activate.
10.0 Maintenance
At least once a year, the range and coverage should be verified. To ensure continual daily operation, the end user should be instructed to walk through the far end of the coverage pattern. This ensures an alarm output prior to arming the system.
11.0 Coverage Patterns
The DS860 has a standard broad coverage pattern or an optional long-range coverage pattern. The protected coverage area is where the microwave and PIR patterns overlap.
An optional Look Down lens is located under the detector. This lens must be unmasked before it is operational. Use caution to remove the black mask only. Do not attempt to remove the white lens assembly. The Look Down lens is not recommended for installations containing pets or small animals. The Look Down zone is shown in black on the Coverage Pattern drawings.
Diagrams illustrating Standard Broad Coverage and Long Range Barrier Coverage, including Top View and Side View diagrams are present in the document.
11.1 Pattern Masking
The PIR coverage pattern may be masked using masking tape or electrical tape on the inside (grooved side) of the lens to cover the appropriate pattern areas as shown in the following illustrations. Always walk test for the desired coverage after masking.
Illustrations for standard and long range barrier lens pattern masking are shown.
NOTE: Masking only eliminates the PIR portion of the coverage and has no effect on the microwave pattern.
