The JA-81M wireless magnetic door detector & universal transmitter
The JA-81M is a component of Jablotron’s Oasis 80 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 ratchet-wheel movements. Small movements are
filtered out so that wind blasts do not cause false alarms.
The battery-powered detector communicates via OASIS radio protocol.

Open / closed status detection
The detector is factory-set to indicate both opening and closing so that the
control panel knows the status of doors/windows. If a pulse mode is
desired to indicate only opening, keep the tamper switch pressed while
inst al li ng t he ba tt er y. Not pressing the tamper switch gives open and closed
status signals.
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 u sed either as a NC input or a balanced
loop input (EOL resistor 1k). 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.

Wiring example for NC contacts
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.

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. 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 5mm 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:
1. Enter enrollment mode on the control panel by keying in “1” in
Service mode.
2. Install a battery into the detector to activate enrollment.
3. Exit enrollment mode by pressing “#”
After installing a battery into the detector, allow up to 30 seconds fo r
stabilisation. During this period the LED is continuously lit.
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
Wiring example for NO contact
IN2 The IN2 input terminal receives signals from the ratchet-wheel.
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.
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
ALARM
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 Oasis control panel.
It also has no effect when used with a
UC-8x or AC-8x receiver.
Opening the cover makes the detector react with a tamper signal.
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 is 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 triggerin g of the detector with a flash
of its LED. Battery replacement should not be d elayed 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.
