Installation Instructions

Description

The 5812-RND is an acoustic glassbreak detector designed

to detect breaking glass from framed windows in the

perimeter of a building. The detector is mounted in the

building interior and uses a power supply from a 12VDC

control panel. The detector is available in a low-profile

round housing.

Features

The detector provides the following features:

• Range - 5 to 25 feet (1.5 to 7.6 m)

• Alarm memory - After an alarm and until power is

cycled, the alarm memory can be checked with the hand-

clap test.

• LED indicator - Red LED provides detector test and

status indication.

• Tamper resistant - Provides a screw that secures the

cover to the base to prevent tampering.

• Hand-clap test - In addition to a test mode, you can

confirm the operation of the microphone by clapping

your hands.

What You Will Need

You need the following tools and parts to install the

detector:

• 5812-RND detector including screw to secure the cover

to the base

• Screws and wall anchors

• Flat-blade screwdriver

• Phillips screwdriver

• Sentrol 5709C hand-held tester

Selecting a Location for the

Detector

The detector can be mounted on ceilings or on walls

opposite or adjacent to the window to be protected. See

Figure 2.

Use the following guidelines to determine the best location

to install the detector.

• Mount at least 5 feet (1.5 m) from glass windows

being protected.

• Windows must be at least 12 x 24 inches

(30.5 x 61 cm) square.

• Avoid locations where lined, insulating, or sound

deadening drapes are used.

• Mount 12 inches (30.5 cm) away from wall corners.

• Avoid locations where interior closed wooden

shutters are used.

• Locate in a suitable envionment as follows:

- Temperature between 32° and 122°F (0° and 50°C)

- Humidity between 10 and 90% non-condensing

• Mount the detector on a stable surface up to 25 feet

(7.6 m) from the farthest point on the glass surface.

See Figure 2.

• Avoid locations that expose the detector to possible

false alarm sources such as:

- Glass airlocks and vestibule areas

- Kitchens

- Residential car garages

- Small utility rooms

- Stairwells

- Bathrooms

- Small acoustically live rooms

- Air vents

Selecting the Best Location for Multiple Window Coverage The detector has a 360degree coverage pattern that can be used to cover several windows in a single room as follows: • Draw an imaginary line from the center of each window to be covered in towards the center of the room. Ceiling mount 60 max. Detector 60 max. • Mount the detector as close to where the lines intersect as possible. See Figure 3.

Testing the Detector To verify detector range and operation, you need the Sentrol 5709C hand-held tester. Use the following steps to test the detector: 1. Set the tester to the appropriate glass-type setting. Use the tempered setting if you are unsure about the glass type. 2. Put the detector in test mode as follows: - Hold the tester 1” from the detector. See Figure 8. GND +12V N.C. COM Figure 7. Wiring Terminals - Activate the tester.

Using the Hand-Clap Test and Alarm Memory The alarm memory and microphone operation can be checked with the hand-clap test as follows: 1. Standing under the detector, clap your hands together. 2. Observe the LED on the detector. If the detector has power and is functioning properly, the LED quickly flashes twice. If the detector has alarmed, the LED will light for 4 seconds. Cycle the power to clear the alarm memory.
