DMP Electronics 1125 Installation Sheet

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 fields, 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 field 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)
