Service explanation for JA-89P
1 Installation
Choose the appropriate location for mounting the detector taking into account the following:
1. Install the detector in a perpendicular line to the ground to make the upper detection area parallel to detect.
2. Installation height is 0.8 - 1.2 m
3. Mount the detector in such a way that most of the movement area falls within the detection pattern.
4. Too much light such as strong sunlight directly on the sensor may cause an unstable condition. It is strongly recommended to avoid this.
To open the detector:
1. Unscrew the lock and remove the top of the housing.
2. Unscrew the screws from the back plate. Remove the base plate.
Please note: never touch the surface of the PIR sensor.
Fix the detector in the desired location. The detector can be mounted directly on the wall or by using the supplied mounting bracket on the pole (Ø 43 - 48 mm).
2 Teaching the detector to the receiver
The transmission module is placed under the optical part of the detector. First study the installation manual of the receiver unit (control panel) to learn how to enter the teach-in mode. When the receiver is in learning mode, insert the batteries in the detector (polarity is indicated in the detector). The detector will give a teach-in signal after the batteries are installed.
JA-81M transmitter module
- Use DIP switch No 1 to change the system's response:
- instantaneous (ON position)
- delayed (position 1).
- Leave DIP switch No 2 in the ON position.
3 Adjustment
The upper detection area remains parallel to the ground. The lower area moves as given below depending on the position of the switch. The detection length is therefore limited by the length of the lower detection area, since the upper and lower areas must both be activated at the same time to trigger the detector.
Detection length setting table:
| Positie | Max. detection length | |
| Standaard | SeeCAUTION under table | |
| A | 12 m | 10.0 to 15.0 m |
| B | 8 m | 6.0 to 10.0 m |
| C | 5 m | 4.0 to 5.5 m |
| D | 2 m | 1.5 to 2.5 m |
Please note that the maximum detection length may vary as above due to ambient temperature conditions.
Active area angle is 90°. By holding the pyroelectric unit, it can be rotated in the desired direction ( in 15° increments).
Demarcating area- by using the supplied shielding plates, the detection area which is exposed to the reflection of sunlight, car light etc. can be shielded.
Sensitivity of the PIR sensor can be set at the "SENS" switch in 3 steps:
L- low
M- medium
H- high
Other settings can be changed with a DIP switch:
The LED indicator is used for testing the PIR detector. During normal operation, it is recommended to switch it off to save batteries.
Depending on the position of the 120s/5s battery saving timer DIP switch, the motion sensor will be blocked for a period of 5 or 120 seconds after a motion is detected or to save batteries.
Depending on the position of the pulse count DIP switch, the detector (above & below detection area) needs to be triggered 2 or 4 times to send an alarm signal.
4 Operation test
Turn on the LED indicator, set the "battery saving timer" to 5 seconds and close the detector. Every 5 seconds, any movement in the detection area will be displayed by the LED indicator and alarm information will be sent to the control panel.
5 Operation
To increase battery life, it is highly recommended to set the "battery save time" to 120 seconds and turn off the LED indicator in normal mode. The motion sensor will be shielded for 5 or 120 seconds after detecting a movement. This means that if there is constant motion in the area the detector will only send this motion information once every 5 or 120 sec.
6 Testing and replacing batteries
The detector checks its battery status automatically. If it is necessary to replace the batteries, the detector will inform the system. If battery replacement is displayed, they must be replaced as soon as possible (within one week).
Before replacing the batteries, the receiver (control panel) must be put in the mode that allows opening the detector (User or Programming mode).
Use only high-quality AAA alkaline batteries for replacement
Please note:Dispose of batteries safely depending on the type and local regulations. Although this product contains no harmful materials, we recommend returning the product to the factory or retailer immediately after use.
7 Problem resolution
| Probleem | Waarschijnlijke oorzaak | Oplossing |
| Detector gives false alarm | Lower detection area is unnecessarily long | Set the detection area properly |
| Detection area receives reflection from the reflector, sunlight, car light, etc. | Remove the reflector, shield the area exposed to the reflection of light or change the position of the detector. | |
| There is a heat source in the environment that can cause rapid temp. change (oven, stove, etc.) | Remove the source of heat or change the position of the detector | |
| There is a moving object in the area (clothes on the clothesline, plants, etc.) | Remove the moving object or change the position of the detector. | |
| Occasionally no detection | Detection area is not set properly | Set the detection area correctly |
| Sensitivity is too low | Change sensitivity to medium (M) or high (H). | |
| Detector does not work | Low battery level | Replace battery |
| LED does not light | Set the LED switch to ON | |
| LED lights up but no response to control paneer | The control panel is out of range, check the battery, try moving either the detector or the control panel. |
