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.

Two 3V Lithium batteries, type CR-123A. For UL installations, use Panasonic, and GP only
1400 mAh
Typically over 5 years

Note: Inability to connect with wireless network, or wireless link quality no higher than 20% may

significantly reduce the expected battery life.

Performed immediately upon battery insertion and periodically after every several hours

3 seconds
Red LED lights for about 3 seconds upon transmission of alarm & tamper messages and upon motion

detection in the walk test mode only.
Red LED flashes during the power-up stabilization period, or after restoring (pressing) the tamper switch.
Red LED does not light upon transmissions of supervision messages or alarm detection after termination
of walk test mode.
Rearms the detector 2 minutes after the last alarm. Timer disabled in the walk test mode
