Glassbreak Detector

Installation Instructions

The Acuity AC-500 is a glassbreak detector designed to

provide reliable protection for residential and commercial

applications.

The AC-500 is integrated with an advanced microprocessor

based glassbreak sensor, designed to detect the sounds

produced by the shattering of framed glass. The glassbreak

detection scheme used on the AC-500 is a result of an extensive

research program, which studies the properties of glass as well

as the properties of sounds produced by the shattering of

framed glass.

Features

• Omnidirectional microphone

• High level static and transient protection

• Excellent RF immunity

• Microcontroller-based digital signal processing

technology

• Dynamic Signal Processing* provides accurate detection of

plate, float, laminated, wired and tempered glass types,

while rejecting common "bell" or "ringing" type sounds

• White noise rejection mechanism

• Installer test mode for glassbreak sensor

• Alarm memory (latching LED) for glassbreak sensor

• 1 year warranty

Locating the Detector

Acuity AC-500

NOTE: Maximum distance 'D' is limited by the range

(refer to the Glassbreak Detector Range chart)

* Patented

For optimum glassbreak protection, the detector should have a

clear view of the protected glass. Curtains, blinds, and other

window coverings will absorb sound energy from the shattering

glass. In these cases, mount the detector as close as possible

to the protected glass.

OTE: : : : : Do not mount the detector on the same wall as the

protected glass.

Avoid installation near noise sources, such as speakers or

other objects, which produce sounds continuously. Do not

install the detector beyond the maximum recommended range,

Test for false alarm immunity by creating any sounds in the

room which will likely occur when the detector is armed.

Consider the following to reduce false alarms:

Noise Sources

Although the Acuity AC-500 is designed to be immune from

OFF

ringing, bell and white noise sounds, avoid mounting the

detector near such sources (e.g., telephones, doorbells,

th premises are unoccupied.

Mounting

To open the case, gently twist the top cover counter-

clockwise and lift it up from the bottom cover. Use a small

screwdriver to remove the appropriate knockouts for wiring.

Mount the bottom cover using the screws supplied.

To close the case, use the locating line on the bottom cover

to align the tab on the top cover. Once the top cover is

engaged, twist the top cover clockwise to lock it in place.

Use the securing screw provided for Listed installations.

NOTE: Since no adjustment is necessary for the circuit

board, it is not recommended that the installer remove the

circuit board from the case. The microphone should NOT be

touched.

Wiring

Power

Contacts shown with power applied in the non-alarm state

NOTE: The unit must be connected to a Listed power supply

capable of providing 4 hours of standby power.

NOTE: After installation, the detector should be tested

annually by the installer.
