JS-25 „COMBO“ P.I.R. & glass break detector
The JS-25 COMBO is an outstanding “two in one” detector, which
dramatically simplifies alarm installations.. This detector combines two
sensors (P.I.R. motion & acoustic glass break) in one housing. It provides
three independent outputs (P.I.R. alarm, glass break alarm and tamper).
The signal from the P.I.R. sensor is electronically analyzed. This
ensures that the detector provides excellent sensitivity and at the same
time false alarms are basically eliminated. The detection analysis rate can
be adjusted to increase its immunity if the JS-25 is installed in a
problematic location. The standard lens in the detector can be replaced
with an optional corridor or pet immune lens.
The dual technology glass break detector analyses air pressure
changes and sounds to detect the breaking of a glass window. The signal
processing guarantees a high sensitivity to the breaking of all types of
glass. The sensitivity can be adjusted to match various window sizes and
mounting distances. A memory feature enables the user to determine,
visually, which detector triggered the alarm.
For testing, the JS-25 is equipped with two LED indicators (red
confirms a P.I.R. alarm, green confirms a glass breaking alarm).
The COMBO distinguishes itself as a unique 2 in 1 solution with
excellent RF immunity.

Installation
The detector is designed for indoor applications. It can be mounted on
a flat wall or in a corner. Do not place the detector close to any
heating/cooling vents or near any other object that often changes
temperature. Do not place the detector close to any apparatuses that can
generate air pressure changes, low frequency noise or vibrations.. The
unit must have an unobstructed view of the protected area and glass.
1.
Open the cover of the detector
(press in the plastic tab on the bottom
with a screwdriver).
2.
Disconnect the cable
connecting the front cover with the main PCB.
3.
Remove the main PCB
by pressing the flexible tab.
4.
Punch through the pre-formed holes
for cables and screws.
5.
Attach the housing to the wall
(2.5 meters above the floor).
6.
Return the PCB into the housing
and connect wires to the terminals.
7.
Re-connect the cable and attach the cover
.
Note:
Avoid touching the P.I.R. sensor!

Jumpers
LED
the red PIR indicator can be disabled by opening this jumper
DETECTION
removing this jumper enables a higher rate of analysis and
increases the immunity of the PIR detector. This setting is
suitable for problematic locations with temperature changes or
electromagnetic interference.
MEM/TEST
sets the green LED glass break indicator. In the
TEST
position,
this LED indicates air pressure changes by a quick flash and
an alarm triggering by a long flash. In the
MEM
position the
LED indicates a broken glass alarm memory. When the jumper
is disconnected, the green LED is disabled.
PIR detector testing
x
After switching on the power wait for 1 minute. During this period the
detector initializes and stabilizes its parameters (red LED will be on if
not disabled).
x
Each detected movement will be indicated by the detector’s red
indicator (if not disabled).
x
Check if the detector covers the protected area as you expected.
Glass break detector testing and adjustments
Set the MEM/TEST jumper to the TEST position (green LED will
indicate the triggering).
x
Strike carefully the glass with a cushioned instrument.
Attention
, do not break the glass!
x
The green LED will flash shortly after a strike, if the air pressure
sensor sensitivity is suitably set. The sensitivity can be adjusted
using the variable resistor. Do not adjust too an excessively high
sensitivity.
x
For complete testing of the detector it is recommended to use the
GBT-212 glass break simulator. The green LED will light for 2
seconds if glass breaking is detected.
