IEI Technology TRI-GARD 555LS Signature Series User manual

TRI-GARD 555LS/557LS SIGNATURE SERIES™
audio glassbreak detectors employ state-of-the-art Advanced
Signature Analysis™ algorithms to sample four bands of audio
instead of one or two like most other detectors. Digital Signal
Processing(DSP)isusedtocontinuouslysampleandanalyze
the sound. Within milliseconds after an audio “event” begins,
themicroprocessorstarts crunchingdata.Approximately1200
comparisonsanddecisionsaremadebeforeaneventisreject-
ed or confirmed about 0.3 seconds later. Eight glassbreak sig-
nature models and four false alarm models, stored in memory,
are referenced during the confirmation process. The result of
thishigh-techperformanceis more accurate glassbreak detec-
tionandimprovedfalse alarm rejection in tough environments.

Audio Glassbreak Detectors
NOTE 1: The use of mini-blinds, shades, drapes* and sun film* can
reduce the range of the detector by 50%. Since room acoustics and win-
dow coverings can vary considerably, all detector installations should be
checked with the 517 tester.
* Not for sound deadening drapes
* Tested w/ 3M sun film #SH2CLAR (3M is a trademark of 3M Company)

MOUNTING LOCATIONS
TheTri-Gardcanbemountedonanytypeofceilingorwall.
The detector should be no closer than 4 feet from the glass to
be protected.Since the sound waves of breaking glass travel
directionally out at a 90° degree angle from the broken win-
dow, the best mounting location is on the opposite wall,
assuming the wall is within detection range.
Formaximumperformanceinstallthedetectorindirectline of
sighttoallglassthatyou are protectingandlocatethedetector
atleast1footfromany corner orceiling.
Forbestfalsealarmimmunitythe detector shouldbemounted
atleast4’fromtheglass to beprotectedandfromnoisesources
suchaskitchensinks,stereos,televisions,etc.
WALL MOUNTING
Mount the detector on an opposite or adjacent wall from the
glass to be protected.
The unit should be mounted at least 6 feet from the floor. This
will ensure that no furniture or other objects will block the
direct line of sight, thereby providing maximum glassbreak
protection.
NOTE:The unit should not be mounted on the same wall as
the glass to be protected.
CEILING MOUNTING
Mount the 555LS/557LS in any location on the ceiling which
is in direct line of sight of the glass to be protected.
To ensure maximum glassbreak detection do not mount the
detector within 1 foot of any side wall.
Mount the 555LS/557LS on any solid material.
555LS/557LS OPERATIONS AND WIRING
On power-up the microprocessor will momentarily turn on
each LED.
LEDs Operation:
• Green LED ON–solid indicates unit is properly powered.
• Green LED OFF–indicates that the relay has dropped out,due
to the detector being tripped or no/low power (<10VDC).
• Green LED BLINKS–slowly to indicate that the unit is in test mode
(see test mode).
•Green LED FLASHES–when there are background noises
present within the detection range.
•Amber LED ON– solid indicates that the “Signature Supervision”
has not been able to test all circuits within the last120 hours.
• Red LED ON–solid indicates that the detector has been tripped
and is in a latched alarm memory condition.
• Red LED FLASHES–to indicate that there is an alarm for low
power condition, input voltage is (<10VDC).

PRE-TESTING THE TRI-GARD 555LS/557LS
FOR DESIRED LOCATION
Pre-testing of the detector prior to final installation can be
performed to ensure that the detector is installed in the
proper location with respect to all glass being protected.
The IEI 517 Glass Break Simulator is required to perform
this test.
WARNING:
The 555LS/557LS detector has been designed to detect
glass break within a specified range from the glass–(25' for
plate, tempered,and wired glass glass and 20' for laminated
glass).You should not extend past these rated ranges for any
reason. Acoustics of different areas can artificially extend the
range of the tester.
1) Connect a 9Volt DC alkaline battery or 12 VDC power
source.
2) Proceed to section: Testing the 555LS/557LS
NOTE: the red LED will flash slowly indicating low voltage
(input voltage <10VDC) and also the relay will not be ener-
gized (common and normally closed will be open).
