The JA-181M wireless magnetic door detector & universal transmitter
The JA-181M wireless magnetic door detector & universal transmitter 1/2 MHQ55802
The JA-181M is a component of Jablotron’s alarm system. It is
designed to detect the opening of doors, windows etc. It can also
be extended by a normally closed / normally open sensor. It is also
designed to detect the handling of roller blinds. This is achieved by
detecting CT-01 ratchet-wheel movements. Small movements are
filtered out so that wind blasts do not cause false alarms. The
JA-181M can be used with the LD-81 flood detector as well.
Installation
Installation shall only be undertaken by technicians holding a
certificate issued by an authorized distributor. This detector reacts
to the removal of its magnet unit. The electronics should be
installed onto the non-moving part of windows or doors, and the
magnet onto the moving part. The detector should be installed
vertically. Avoid locating it directly on a metal frame as metal
influences the functioning of the magnetic sensor and radio
communication. If the door or window is made of metal, we
recommend installing the detector unit away from the metal and
wiring up an external wired magnetic sensor which is connected to
the detector.
There are two different types of permanent magnets in the
package - a standard magnet in a plastic housing (A) and a whorl-
shaped magnet (B) for use in places where there is not enough
space for a standard magnet or for counter-sinking the magnet into
a door or window’s inner frame. The right positions for placing both
types of magnets against the internal magnetic sensor are shown
below as well as the reaction areas for magnets in millimeters in
three axes of movement.
See the following instructions:
1. Open the detector cover by pressing the tab in.
2. Screw the rear cover to the solid part of the door/window.
3. Attach the magnet to the moving part of the window. Its
distance from the detector should not exceed 5 mm when the
door/window is closed. The lower edge of the magnet should
be aligned with the lower edge of the detector. Only a single
magnet can be installed, either on the left side or the right side
of the detector.
4. Leave the battery disconnected and the cover open and
then follow the control panel or receiver manual. The basics of
enrollment are:
xEnter enrollment mode on the control panel by keying in “1”
in Service mode
xInstall a battery into the detector to activate enrollment.
xExit enrollment mode by pressing “#”
5. To observe EN 50131-2-6 must be the tab must be secured by
the supplied screw.
To enroll a detector after having already connected a battery,
first disconnect the battery, and press and release the tamper
sensor to discharge any remaining charge to ready the device for
enrolment.
DIP switches
MG ON / MG OFF Allows the internal magnetic sensor inside
the detector to be disabled when the detector is only to be used
with external sensors wired to its terminals.
INS / DEL DEL provides entrance & exit delays for detectors
installed in a building entrance. INS allows the detector to instantly
trigger alarm activation if the control panel is armed. This DIP
switch (INS/DEL) only has an effect if the detector has a natural
reaction assigned to its address in the Jablotron control panel. It
also has no effect when used with a JA-182N or JA-180N receiver.
Opening the cover makes the detector react with a tamper
signal.
Open / closed status detection
The detector has two different modes. The mode is indicated
by one or two short flashes when the battery is inserted.
One flash means that it indicates both opening and closing the
door or window (factory default setting). The control panel knows
the status of doors / windows. Two flashes means the pulse mode
in which the detector indicates only opening the door or window.
The mode can be set (changed) when keeping the tamper switch
pressed while installing the battery for 3 to 5 seconds.
Wiring up the external sensor
External sensors can be wired to the detector. It is possible to
protect more doors / windows or to wire in other types of wired
detectors. The inputs IN2 and TMP react when disconnected from
the GND common terminal. The IN1 input can be used either as a
NC input or a balanced loop input (EOL resistor 1 k). The function
is detected automatically.
IN1 If the IN1 terminal is disconnected from GND it sends the same
signal to the control panel as if the magnet had been removed
from the detector. The internal magnetic sensor can be disabled by
the DIP switch if desired.
The balanced loop feature can be used when the connection of a
detector with a NO output is needed. The resistor is then shorted
out by the closing contact and the detector is triggered.
Wiring example for NC … and NO contacts
IN2 The IN2 input terminal receives signals from the ratchet-
wheel CT-01. Alarm signals are then only transmitted when the
ratchet contact is opened at least three times within 10 seconds.
This filters out disconnections caused by accidental ratchet-wheel
shifts, which are due to wind blasts. When the IN2 input is opened
for more than 1 sec a tamper signal is sent.
Ratchet-wheel function scheme
TMP The TMP terminal sends a tamper signal to the control
panel if disconnected from GND.
Note: If any of these two inputs is not used, it must be shorted to
the GND terminal.
The maximum length of the cable for external detector
would not be longer than 3 meters.
Testing the detector
15 minutes after closing the detector cover, the LED indicates
detector triggering. The strength and quality of detector signals can
be measured by the control panel in Service mode.
Battery replacement
The detector monitors its battery voltage and if too low, a
transmission is sent to the control panel to inform the installer or
user. The detector continues to function and shows each triggering
of the detector with a flash of its LED. Battery replacement should

The JA-181M wireless magnetic door detector & universal transmitter 2/2 MHQ55802
not be delayed by more than two weeks. This should be done by a
qualified technician with the control panel in Service mode.
Expired batteries should not be thrown into the garbage, but
disposed of according to local regulations.
Removing the detector from the system
If a detector is removed, the control panel announces the
removal. The detector has to be deleted in the control panel before
intentional removal.
