General Information

The DS825 Series and DS840 Series are microprocessor-based

TriTech Passive Infrared/Microwave Intrusion Detectors that provide

immunity to false alarms caused by pets [a dog up to 100 lbs.

(45 kg) or up to 10 cats, and other small animals such as birds

and rodents]. Patented Passive Infrared and Microwave signal

processing provides excellent catch performance with freedom

from false alarms.

Specifications

•

Input Power:

6 to 15 VDC, 15 mA DC nominal (up to

35 mA DC during walk testing).

•

Standby Power:

No internal standby battery. Connect to

DC power sources capable of supplying

standby power. For each hour of

standbytime needed, 15 mAh are

required.

For UL Listed Requirements,

four hours (60 mAh) are required.

•

Alarm Relay:

Silent operating Normally Closed reed

relay. Contacts rated 3 W, 125 mA,

28 VDC maximum for DC resistive

loads; and protected by a 4.7

Ω

,1/2 W

resistor in the common “C” leg of the

relay. Do

not

use with capacitive or

inductive loads.

•

Temperature:

-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).

•

Microwave Frequency:

DS825(T)/DS840(T):

10.525 GHz (UL Listed)

DS825TA/DS840TA:

10.687 GHz (Export only, not UL Listed)

DS825TB/DS840TB:

9.9 GHz (Export only, not UL Listed)

•

Coverage:

DS825 Series:

25 ft. x 25 ft. (8 m x 8 m)

DS840 Series:

40 ft. x 40 ft. (12 m x 12 m)

•

Internal Pointability:

+1° to –18° Vertical.

•

Optional Tamper:

The DS825T, DS825TA, DS825TB,

DS840T, DS840TA, and DS840TB

have a Normally Closed (with cover on)

tamper switch. Contacts rated at

28 VDC, 125 mA max. Connect the

tamper circuit to a 24-hour protection

circuit.

•

Options:

B335 Low Profile Swivel Mount Bracket

and B338 Ceiling Mount Bracket. (The

use of brackets may reduce range and

increase dead zone areas.)

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.

3.1

Mounting Considerations

•

Never

install the detector in an environment that causes a constant

alarm in one technology; it should never be left to operate with

the tri-color LED in a constant green, yellow, or red condition. A

detector with one technology in constant alarm, will cause an

alarm output whenever the other technology alarms. Good

installations start with the LED

OFF

when there is no target motion.

The best installations will have background noise voltages below

recommended limits.

•

Point the unit away from outside traffic (e.g. roads, alleys, and

parking lots).

NOTE:

Microwave energy will pass through glass and most

common non-metallic construction walls.

•

Avoid direct or indirect sunlight.

•

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.

•

Avoid installations where rotating machines (e.g. ceiling fans) are

normally in operation within the coverage pattern.

•

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). The

recommended height is 7.5 ft. (2.3 m). Mounting height for Pet

Applications is

6.5 ft. (2 meters).

3.2

Mounting the Detector

•

Remove the cover by inserting a thin flathead screwdriver into

the locking tab hole at the bottom front of the detector, pressing

in, and pulling the cover up and forward.

NOTE:

Mount the unit with the terminal block up.

•

Remove the circuit board from the base by pulling outward slightly

on one of the Circuit Board Locking Tabs (see Figure A).
