EC DECLARATION OF CONFORMITY
Hereby, Vanderbilt International (IRL) Ltd declares that this
equipment is in compliance with all relevant EU Directives for
CE marking. From 20/04/2016 it is in compliance with Directive
2014/30/EU (Electromagnetic Compatibility Directive).
The full text of the EU declaration of conformity is available at:

DESCRIPTION
AGB800-AM is an acoustic glass break detector giving an
alarm when glass is smashed at intruder attempts through windows, doors and glazed walls.
The detector is based on advanced microcontroller technology
and programmed to take a lot of relevant acoustic factors into
account: The Digital Room Compensation (DRC). This makes
the detector able to distinguish between a true glass break and
other irrelevant sounds.
The detector is for indoor use. The coverage distance is 1–9 m.
The coverage angle is 165º, which means that one detector can
protect several windows in the same room. The detector can
be mounted in the ceiling or on a wall with a free “line-of-sight”
to the window being protected.
AGB800-AM is equipped with an AM function, a separate relay,
which gives an alarm at sabotage of microphone.
AGB800-AM is certified according to EN 50131-2-7-1:2012,
security grade 3.
Coverage area in the acoustic room Zone 1–3
CONNECTION TO A 24-HOUR LOOP
The detector is constructed for continuous supervision and is
extra resistant to different acoustic disturbances. It will function
well in most environments. However in rooms with very high
rates of disturbances as in industrial workshops and gyms, it is
recommended to test the detector for 3–4 weeks before deciding to use it continuously. In rare cases a combination of random sounds can trigger an alarm.
SIGNALLED EVENTS
Detector has two relays and one micro-switch to signal detected and processed events to control panel in prioritised order
as following signals:
Glass break – signalled by INTRUSION relay
Low power supply voltage or self-test fail – signalled by
FAULT relay
Masking – signalled by INTRUSION and FAULT relay
Sabotage is signaled independently by TAMPER micro-switch.
Signal sent by relay or micro-switch
SPECIAL TOOLS
In most rooms (e.g. offices) no special tools are required during
the installation. In rooms with complicated acoustics it is recommended to use the ADT700 tester. ADT700 can also be
used for function test and annual service.

UNDERSTANDING THE DIP SWITCH
DIP1=ON: INTRUSION relay mode ON means the INTRUSION relay will Latch and be open in alarm.
DIP1=OFF: INTRUSION relay mode OFF means the INTRUSION relay will be auto reset after 2 seconds in alarm.
10. Set the desired range, i.e. the detector sensitivity setting
by using the DIP switch no 2 and 3.
11. Check the window constructions and note what kind of
glass is used and especially in the pane closest to the
room.

SUGGESTED SETTINGS OF THE DETECTOR DEPENDING ON WINDOW DESIGN AND TYPE OF GLASS:
Check the window constructions and note what kind of glass is
used and especially in the pane closest to the room.
Single glazed (float & tempered) – Set the detector at the
measured distance from the glass to the detector.
Double glazed (float & tempered). If there are high disturb-
ances in the surroundings – set the detector at the measured distance from the glass to the detector. At normal or
low disturbances – the detector shall be set at Zone 1.
Double glazed where the inner pane is covered with secu-
rity film – Set the detector at Zone 1 apart from the meas-
ured distance.
Triple glazed (float & tempered) – Set the detector at Zone
1 apart from measured distance.
Laminated glass – Set the detector at Zone 1 apart from
the measured distance.
Glass type of pane inside room
Double glazed with security film
CHECK THE SETTINGS WITH ADT700 TESTER
If the detector is placed too far or too close from the glass, it
will not respond. At DRC testing the LED of the detector will
flash 1, 2 or 3 times to show it is in a certain Zone. If it does not
flash a better place must be selected.
1. Put the cover on and make sure it hooks properly into the
base of the detector.
2. Apply power – LED will now indicate your range setting by
blinking 1–3 times.
3. Use ADT700 to test and calibrate the detector for optimal
position.
TESTING AND CALIBRATING
ADT700 tester is a specially developed tool for calibrating and
adjusting the detector AGB800-AM for optimal function in the
acoustic room – the DRC Digital Room Compensation procedure. When testing the detector settings you do not need to
open it again as the tester will communicate with the detector
acoustically. Never test the AGB800-AM with a cover disassembled from a base. Make sure the cover is fastened properly.
Caution: Do not use the ADT700 tester in proximity to your
ears as the tester produces loud noises.
DIGITAL ROOM COMPENSATION PROCEDURE
Prepare the acoustic detector for DRC by setting the D/N line
(if used) in DAY mode – D/N line should be left open or Low.
1. Press the START button of the ADT700 tester to put the
power on. Green LED will light.
2. Hold the tester 1 to 3m from the detector and aim the
speaker at it.
3. Press the START button once more to initiate the DRC
mode. The LED on the detector will start to flicker.
4. Go to the furthest distance (max. 9m) of the glass to be
protected and aim the speaker at the detector.
5. The DRC range calculated by the detector will be displayed as a number of pulses from 1 to 3.
Press the DRC button to send a DRC signal out. Make this 2–
10 times from different angles of the protection area for optimal
capability. The LED will flash confirming it has received the signal. The LED will then start to blink and flicker. The DRC range
calculated by the detector will be displayed as a number of
pulses from 1 to 3. In case of too weak or too strong signals
outside the compensation range (means that the detector is
placed too close or too far from the object to be protected), the
detector will then not show DRC range.
6. Press the STOP button from a distance of 1 to 3m from the
detector to terminate the DRC procedure.
If DRC range measured by the detector is different from actual
DIP-switch settings, the LED will continue to blink 1–3 times
showing the correct range number to be set in the detector.
The LED blinks 1 time: set to Zone 1 (4–9 m)
The LED blinks 2 times: set to Zone 2 (2–4 m)
The LED blinks 3 times: set to Zone 3 (1–2 m)

PROTECTING SEVERAL WINDOWS BY ONE DETECTOR
Detector can protect several windows in one room if the windows are within the coverage area. Make independent DRC
test for each window to be protected. Follow the procedure
above for each window. The detector shall be set to the lowest
Zone number that is the longest range from the detector.
TIMEOUT
Both the AGB800-AM detector and ADT700 tester are
equipped with a timeout feature. The AGB800-AM will stop the
DRC mode and the ADT700 will switch off power if no activity
has happened within 3–4 minutes.
D/N CONTROL (Day/Night)
The D/N makes it possible to remote control the alarm indications of the detectors and remote reset during DAY->NIGHT
transition. The D/N increases the security of the detector, as it
enables the alarm indications to be concealed in NIGHT mode
without any influence on the relay function.
SELF-TEST
Detector is continuously checking all vital parts responsible for
proper detection of glass break signal using internal self-test
procedure.
ANTI-MASKING
Test of antimasking system:
1. Put the power on. Seal microphone completely with elastic
material like chewing gum or isolation tape.
2. INTRUSION and FAULT relays will open after max. of 180
s signaling masking of microphone.
3. Remove sealing material from microphone. Relays will
close in less than minute.
