JA-81M

Service instructions for JA-81M

1 Installation

Installation should only be done by a certified technician approved by an authorised distributor.
This detector responds when its magnet is removed. The detector should be stuck on the non-moving part of a door or window, and the magnet on the movable part. The detector must be placed vertically. Avoid placing it on metal parts that may interfere with its magnetic property and/or radio signal. If the door or window is metal, we recommend hanging the detector somewhere else and connecting a wired magnetic contact to the detector.

See the following instructions:
1. Open the housing by pressing the tab at the bottom.
2. Screw the back onto a non-movable part of the door or window.
3. Attach the magnet to the movable part of the door or window. The distance to the detector should not exceed 5mm when the door or window is closed. The bottom of the detector should be flush with the bottom of the magnet. Only one magnet can be placed, this can be to the left or right of the detector.
4. Do not insert the battery yet and leave the housing open. Follow the manual of the central unit or receiver.

The basic method of learning is as follows:
1. Activate teach-in mode by pressing "1" in service mode.
2. Insert the battery in the detector to register the detector.
3. Exit learn mode by pressing "#".
To enroll the detector if the battery is already inserted; first remove the battery and then press the tamper switch several times to remove residual voltages.

2 DIP switches

MG ON / MG OFF Allows the internal magnetic contact to be switched off if only an external sensor is connected.
INS / DEL With INS, an alarm will be generated immediately when the detector is activated, DEL will start the input delay if the central unit is switched on. The DIP switch (INS/DEL) only has an effect if the detector in the Oasis central unit is set to neutral response.
It has no efect if the detector is used with a UC-8X or an AC-8X receiver. Opening the housing will result in a tamper notification

3 Open/close status detection

The factory setting of the detector allows it to report both the opening and closing of a door or window to the central station. If it is desired to report only the opening of a door or window, hold down the tamper switch when the battery is inserted.

4Connecting external sensor

External sensors can be connected to the detector. It is possible to use them to secure several doors or windows or to connect other wired detectors. There are 2 inputs, IN and TMP which will react if disconnected from the common GND connection
IN: If the IN connection is disconnected from the GND connection, the detector will send the same signal to the central unit as if its own magnet is removed from the detector. The internal sensor can be switched off MBV the DIP switch if this is desired .
TMP: The TMP connection will send a tamper signal if it is disconnected from the GND connection.
Please note: If one of the two inputs are not used, it must be short-circuited to the GND connection

5 Testing the detector

Up to 15 minutes after closing the housing, the LED indicator will light up when the door or window is opened or closed. The signal strength can be measured by the central unit in Service mode.

6 Battery replacement

The detector monitors the battery voltage. If it becomes too low, the detector will send a signal to the control centre to alert the user or technician. The detector will continue to operate and the LED will flash with each activation of the detector. Battery replacement should not be delayed longer than 2 weeks. Replacement should be done by a certified installer when the central unit is in Service mode.
Do not just throw away empty batteries, follow local rules for disposing of batteries.

7 Removing the detector from the system

If the detector is to be removed, first remove it in the central unit and only then remove the detector.
