1125 PIR Motion Detector

Description

The 1125 PIR (Passive Infrared) Motion Detector is a wireless, low current sensor for use with the 1100D Wireless

Receiver. Using mirrored optic technology the 1125 PIR is highly immune to multiple false alarm sources. In addition

to switch-selectable sensitivity and range adjustment, you can use masking to modify coverage patterns for various

applications.

Parts Included

• One PIR detector

• Three 3V lithium CR-123A batteries

• Two plastic masks

• One screw to secure the unit to the wall mounting bracket

• One wall-mounting bracket

• One sheet of adhesive masking labels

• One cardboard undercrawl window mask

For your convenience, two additional pre-printed serial number

labels are included. Verify the serial numbers on the labels match

the serial number located on the back of the device housing. Prior

to installing the device, record the serial number located on the

back of the device housing or place one of the pre-printed serial

number labels on the panel programming sheet. This number is

required during programming.

Selecting a Location

Mount the unit:

• On a rigid vibration-free surface

• 6 to 10 feet (1.8 to 3m) high, but at least 6 inches (15cm) from the ceiling

• So the expected intruder movement is across the detection pattern elds, see Figure 2

Do not locate the unit:

• On a surface exposed to moisture

• In any area containing excessive metallic surfaces

• Where it may be exposed to false alarm sources such as: direct sunlight, heat sources (heater, radiators, etc.)

in the eld of view or strong air drafts (fans, air conditioner, etc.)

• Where the ambient temperature is below 32° F (0°C) or above 131°F (55°C)

INSTALLATION SHEET 1125 PIR Motion Detector Description The 1125 PIR (Passive Infrared) Motion Detector is a wireless, low current sensor for use with the 1100D Wireless Receiver. Using mirrored optic technology the 1125 PIR is highly immune to multiple false alarm sources. In addition to switch-selectable sensitivity and range adjustment, you can use masking to modify coverage patterns for various applications.
PAGE 2
Selecting the Coverage Pattern The unit coverage pattern can be modified to fit specific applications by masking mirror curtains. Mask curtains to avoid sources of false alarms, such as heaters, air conditioners, and windows. Open the unit by pushing the opening tab up. If necessary, use one or more of the following methods to modify the coverage pattern. Using the plastic masks Use one or both of the plastic masks provided to mask off large coverage areas as shown in Figure 3.
PAGE 3
Setting the Sensitivity and Range Switches Use the switches located on the unit back to set sensitivity and range, as shown in Figure 6. Use the following to determine the appropriate switch settings for an application. Mode BI = Bi-curtain Mode (factory default) increases false alarm immunity in smaller areas and requires an intruder to pass through two curtains to trigger an alarm. Do not use for single curtain applications or ranges under 5 feet (1.5 m).

Installing or Replacing Batteries Note: You must remove all batteries to reset the low battery signal before installing new batteries. Always replace all three batteries. Allow three minutes after installing the batteries for the sensor to become operational before initiating a Walk Test. Use only 3V lithium CR-123A batteries. Use the following steps to install the batteries: 1. Remove the unit from the wall mounting bracket. See Mounting the Unit. 2.
PAGE 5
PIR Walk Testing A Walk test Mode for testing the unit operation and coverage pattern is provided. Use the following instructions to walk test the unit: 1. Ensure the 1125 PIR is programmed in the Command Processor™ panel. 2. Lift the unit from the bracket until the tamper switch opens to enable the Walk test Mode. 3. When the unit is remounted on the bracket, the unit remains in the Walk test Mode for 3-4 minutes.
