Wireless Digital Pet Immune PIR Detector

1. INTRODUCTION

The XHS1-TY or MP-841 (pet immune) is a microprocessor-controlled wireless digital PIR detector supported by ZigBee HA 1.2.
The detector’s features are as follows :

• Up to 15 meters (49.2 ft)

• Uniform Detection

• White light immunity (Black mirror technology)

• Enhanced Pet immunity up to 85Ibs (Target Specific Imaging™ (TSI) technology (patented)

• Enhanced false alarm rejection (The advanced True Motion Recognition™ algorithm (patented)

• No vertical adjustment is needed.

• In normal mode, after detection, the detector goes to sleep to save battery power. It wakes again (reverts to the ready state) if there is no

subsequent detection throughout the following 2-minute period.

• Temperature compensation.

• Front and back tamper protection.

• Black mirror technology provides excellent white light protection.

• Elegantly styled, sturdy case.

3. INSTALLATION

3.1 General Guidance

1. Keep away from heat sources.

2. Do not expose to air drafts.

3. Do not install outdoors.

4. Avoid direct sunshine.

5. Keep wiring away from power cables.

6. Do not install behind partitions.

7. Mount on solid stable surface.

1. Press in this point.

2. Push in the direction of the arrow shown in the drawing to
separate the detector from the bracket.

3. Mount the bracket on the wall.

4. Install new batteries.

-OR-

If batteries are already installed, pull the activation strip.

5. Mount the detector on the bracket by sliding it downward until a
click is heard.

A. Use A1 or A2 for corner mounting
B. Use for surface mounting
C. Activation strip

Note: It is recommended to wait about 1 minute after battery removal, before inserting the new battery.

Caution! Risk of explosion if battery is replaced by an incorrect type. Dispose of used battery according to the manufacturer's instructions

3.3 Replacing the Batteries

1. Press upward to separate the detector from the bracket.

2. Replace the batteries.

3. Put back the detector on the bracket.

Figure 7 – Replacing Batteries

3.4 Activating and Pairing the Detector

To pair the detector to the Touchscreen (control panel), you must set it to pairing mode.

1. First set the Touchscreen (panel) to pairing mode and then the detector.

2. To activate, pull the activation strip that protrudes from the back of the detector (see Figure 5).

3. The green LED (see Figure 1) blinks 3 times every 5 seconds (repeated up to 20 times) to indicate that the detector is searching for the
Touchscreen (control panel).

Note: If detector pairing is not successful during the searching process – by tripping the motion detector or by pressing the tamper switch – the

searching process will restart.

4. Complete the pairing procedure on the Touchscreen (control panel) (see the pairing instructions in the Touchscreen / control panel’s installation
guide).

Note: Pairing should be performed before installation.

(Detector installation will have a good link with panel, if RSSI indicated on the Panel higher than -70BM and LQI stronger than 250. If values of

RSSI and LQI are lower, change Detector placement)

3.5 Rebooting the Detector

You can reboot the detector, as follows.

1. Remove the battery cover.

2. Press and release the tamper switch for 1 to 2 sec. (see Figure 1).

3. Close the battery cover.

Problem

Remedy

3.6 Defaulting the Detector

CAUTION! The defaulting process removes the device from the network and enables re-pairing.

Separate the detector from the bracket to remove both batteries. (see Figure 7).

1. Press and hold down the detector’s tamper switch.

2. Insert one of the two batteries into the detector while observing battery polarity.

3. Release the tamper switch within 4 seconds (the LED blinks 3 times every 5 seconds).

4. To re-pair the detector, follow the instructions in section 3.4.

3.7 Walk Testing

Walk across the far end of coverage pattern in both directions. The LED should light for 2-3
seconds each time your motion is detected.

Important! Instruct the user to walk test at least once a week to verify proper function of the

detector.

Note: Upon battery insertion or closing the cover (which results in closing the tamper switch)

the LED flashes for 2 minutes and the detector goes into walk-test mode for 15
minutes. In walk-test mode the LED lights upon every motion detection. After 15
minutes the detector automatically enters normal mode in which the LED will not
blink after detection.

TROUBLESHOOTING

If you encounter one of the following problems with the MP-841, perform the suggested remedy:

Attempt to pair the sensor is unsuccessful. Make sure that the sensor has been defaulted and is set to pairing

The sensor and the Touchscreen (panel) do not communicate. Perform the signal strength testing procedure described in the control

Consult with your installer or system provider before you disable
a zone.

Disable the sensor zone (see the control panel user manual). Note that
disabling a sensor zone lowers the overall security level of your
system.

SPECIAL COMMENTS

Even the most sophisticated detectors can sometimes be defeated or may fail to warn due to: DC power failure / improper connection, malicious
masking of the lens, tampering with the optical system, decreased sensitivity in ambient temperatures close to that of the human body and
unexpected failure of a component part.
The above list includes the most common reasons for failure to detect intrusion, but is by no means comprehensive. It is therefore recommended
that the detector and the entire alarm system be checked weekly, to ensure proper performance.
An alarm system should not be regarded as a substitute for insurance. Home and property owners or renters should be prudent enough to
continue insuring their lives and property, even though they are protected by an alarm system.
This device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in residential installations. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio and
television reception. However, there is no guarantee that interference will not occur in a particular installation. If this device does cause such
interference, which can be verified by turning the device off and on, the user is encouraged to eliminate the interference by one or more of the
following measures:

Re-orient or re-locate the receiving antenna.

Increase the distance between the device and the receiver.

Connect the device to an outlet on a circuit different from the one that supplies power to the receiver.

Consult the dealer or an experienced radio/TV technician.
Even the most sophisticated detectors can sometimes be defeated or may fail to warn due to: DC power failure / improper connection, malicious
masking of the lens, tampering with the optical system, decreased sensitivity in ambient temperatures close to that of the human body and
