**IRMP-23-F1**

IRM-23 Series Motion Sensor is equipped with both PIR and Microwave motion detection technology. The combination of dual detection methods greatly improves the Motion Sensor’s detection accuracy and reduces false alarm rate, by using the PIR as initial detection, and microwave as confirmation before actually transmitting the activation signal.

The Motion Sensor has multiple models with different battery, tamper switch and Pet Immunity combination. Identify the function of your model on hand with following table before proceeding to read rest of this manual.

The PIR is designed to give a typical detection range of 12 meters when mounted at 2 meters above ground.

The Pet-Immune models of IRM-23 series PIR sensor further support pet immunity feature and will not detect pets of up to 27 kg within 7 meter range to minimize false alarm situation.

## Features

### Movement Detection

* The Motion Sensor has built-in PIR sensor and Microwave Transmitter. Motion Detection is performed by PIR Sensor during normal operation. When PIR Sensor detects movement, the Microwave Transmitter will be activated to verify the movement detection. If both PIR and Microwave confirms movement detection, the Motion Sensor will transmit detection signal.
* Detection signal will only be transmitted when both PIR and Microwave detects movement.
* Adjust Microwave Range Switch setting to tune the Microwave Transmitter and overall detection range.
* When Microwave Range Switch is set to Maximum, the Motion Sensor has an approximate range of 12 meters when mounted at 1.9\~2m height.
* When Microwave Range Switch is set to Minimum, the Motion Sensor has an approximate range of 3\~5 meters when mounted at 1.9\~2m height.

### Sleep Timer

After transmitting a detected movement signal, the Motion Sensor will not retransmit for 1-minute sleep period. Any further movement detected during the Sleep Period will reset the sleep time to 1 minute. In this way continuous movement in front of the Motion Sensor will not unduly exhaust the battery.

### Test Mode

The Motion Sensor can be put into Test mode by pressing the Learn /Test button. Test Mode lasts 3 minutes and will be reset to 3 minutes by any Learn/Test button press. When under Test Mode, the Sleep Timer is disabled and the LEDs will light up when the Motion Sensor detects movement to notify user.

Use the Test mode to determine the detection coverage of Motion Sensor when installing the sensor.

### Microwave Test Mode

The Microwave Test Mode is for microwave range test only. Use the JP3 Jumper to enable Microwave Test Mode. When the Motion Sensor is under Microwave Test Mode, PIR detection is disabled, the Microwave Transmitter will be activated to repeatedly send microwave signal for movement detection. When the Motion Sensor detects movement under Microwave Test Mode, the Microwave Blue LED will light up briefly to indicate.

Use the Microwave Test Mode to determine the microwave range and adjust range with Microwave Range Switch if required. Make sure to disable Microwave Test Mode after testing is complete by setting JP3 Jumper to OFF and return the Motion Sensor to normal opeation.

### Battery

* The Motion Sensor uses different battery depending on the sensor model.

<figure><img src="https://1580875003-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FZJzpNocHhYVmD43GZobR%2Fuploads%2Flzx2r8hgkZkZk3mPBQXu%2Fimage.png?alt=media&#x26;token=a33204e4-5d6d-4ed4-bb1b-d913f993a3eb" alt=""><figcaption></figcaption></figure>



* The Motion Sensor features low battery detection, when low battery voltage is detected, a low-battery signal will be sent to the Control Panel along with regular signal transmissions (e.g., transmission of the supervisory signal when Supervision is enabled).
* If supervision is disabled, the low-battery status is transmitted to the control panel every 12 hours.
* If battery is not changed after low battery detection and the battery is fully exhausted, the Motion Sensor will stop all operation. The Red LED will flash every 4 seconds to indicate.
* When changing batteries, after removing the old batteries, press the Tamper Switch or Learn/Test a couple times to fully discharge before inserting new batteries.

### Supervision

If enabled, the Motion Sensor will transmit a supervisory signal once every 30 to 50 minutes

If the Control Panel fails to receive the Supervisory signals transmitted from a certain Motion Sensor for a preset time, the Control Panel will determine the particular sensor is out of order.

### Tamper Switch

The tamper switch on the Motion Sensor operates differently according to Motion Sensor models.

* **IRM(P)-23A Series:** The Tamper switch is in normal position (Tamper closed) when the spring is compressed against the inside of device back cover. Tamper violation happens when the cover is removed from the base and releases the tamper switch.
* **IRM(P)-23B Series** The Tamper Switch protrudes from the hole on device back cover and is in normal operation position when the Motion Sensor is properly mounted and the tamper switch pressed against mounting location. Tamper violation happens when the device is removed from the mounting surface and releases the tamper switch.
* **Break-Away Areas**

The Motion Sensor back cover has 2 hollowed **break-out areas**. When the device is properly installed, if an intruder forcibly removes the Motion Sensor from mounted location, the break-away areas will break off from the back cover and remain attached to the mounting surface while the device main body is removed, activating the tamper switch.

## Learning and Installation

### Getting Started

1. Orient and insert the battery according to polarity.
2. The Red Transmitter LED will begin to flash for 30 seconds to indicate the Motion Sensor is warming up. During the warming up period, the Motion Sensor will not be activated. It is recommended that you stay away from the detection area during this time. After the warming-up period, the Red will turn off and the Motion Sensor will enter normal operation.

{% hint style="danger" %}
_IMPORTANT NOTE_

* For the most desirable performance, remember to adjust the height of the Motion Sensor according to the height of the tallest animal in the house. Taller animals require the sensor to be mounted higher for the Pet Immunity purpose.
* When deciding on the height of the sensor mounting site, remember to take any possible blind spot into consideration. The blind spot underneath the sensor enlarges proportionally to the height of the mounting site.
* Please note that the performance is affected by external factors, such as height of detected object, desired detection range, installation area, etc. The suggested mounting height could be adjusted according to actual installation environment factors.
* When IRM-23 is mounted with rotating bracket, it will not have the regular detection area (as in the above diagram), or the typical pet immue range.
{% endhint %}

* **It is recommended to install the Motion Sensor in the following locations**
  * Mount where the animals cannot come to the detection area by climbing on furniture or other objects.
  * Avoid aiming the sensor at stairways where the animals can climb on.
  * Mount in a position such that an intruder would normally move across the sensor’s field of view.
  * Mount in a corner to give the widest view.
  * Mount where its field of view will not be obstructed e.g. by curtains, ornaments etc.
* **Limitations**
