PIR Motion Sensors
A passive infrared motion detector (PIR) is an electronic security device that
detects intruders by "sensing" motion or body heat in the area being protected.
Most PIRs are designed to be used when your family is away from home or when
no one will be passing through the area "covered" by the PIR.

Recent innovations in security technology have resulted in the creation of "pet
immune" motion detectors-allowing dog and cat lovers to enjoy the same level of
protection they would receive with a standard PIR. These state-of-the-art sensors
provide "pet immunity" for animals weighing up to 80 lbs. Pet immune PIRs allow
your pet to move about freely but can still detect an intruder’s movement.

The ASC Edge:
Automated SMD Construction on the Flex Lines

Ademco has been a pioneer in the use of Surface Mount Device (SMD)
construction in the security industry. Starting with surface mount passive
components like resistors and capacitors, then moving to integrated circuits
like amplifiers, now even sophisticated microprocessors are surface mounted
on ADEMCO's Flexible Manufacturing Lines. All ADEMCO motion detectors,
fabricated using automated SMD construction, providing you with major

1. Higher Reliability: Each component is located precisely by robotic cameras
and each solder connection is carefully controlled by computer.

2. Fewer "out-of-the-box" problems: Because the components are automatically
selected and placed properly on the PCB, there is virtually no opportunity for
error in the fabrication process.

3. Improved RF Immunity: SMD components have no leads that could act as
miniature antennas where absorbing even a minute amount of RF energy can
lead to false alarms in high gain circuits such as PIR motion detectors.
