• Compliance: This device complies with Part 15 of the FCC Rules

and with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including

interference that may cause undesirable operation.

Changes or modifications not expressly approved by Bosch Security Systems can void the user’s authority to operate the equipment.

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 vibrationfree. 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

• 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, ½ 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

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.

Off

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 as shown here:

1234

567

8 9

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 tricolor 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.

INT

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.

STD

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.

If 1-day Motion Monitor is selected, the memory feature must be enabled by cutting the memory jumper. The Motion monitor timer

IMPORTANT

will be suspended when the detector is in night (armed) mode.
