Ceiling-Mounted Passive Infrared Motion Detector

INSTALLATION INSTRUCTIONS

GENERAL INFORMATION

This passive infrared motion detector is a ceiling-mounted unit
employing a 360°, 31-zone Fresnel lens and offering an efficient
protection pattern for commercial and residential applications.
The detector senses sudden and slight changes in temperature
within the area of detection; thus, when an intruder crosses or
enters any zone, the resulting change in infrared energy is
detected for alarm reporting. Best coverage will be obtained if
the PIR is mounted such that the likely direction of intruder
motion is in the direction shown in Figure 1.

The Detector features installer-selectable Alternate Polarity
Pulse Count, which provides protection against false alarms,
and an LED enable/disable feature (installer-selectable).

INSTALLATION HINTS

Do not install where the detector is exposed to direct sunlight

•

or directly above strong sources of heat.

Make sure the detection area does not have obstructions

•

(curtains, screens, large pieces of furniture, plants, etc.) that
may block the pattern of coverage.

Avoid locating a detector in areas that contain objects likely to

•

produce a rapid change in temperature, such as central
heating, radiators or ducts (or heaters of any kind), air
conditioners, open flame, etc.

Do not mount on an unstable surface.

•

Important:

Avoid running alarm wiring close to heavy-duty

electrical power cables.

PROTECTION PATTERNS

The PIR’s protection pattern with the standard lens is shown
below.

TAMPER SWITCH

This PIR is equipped with a cover tamper switch. With cover
on, the switch is closed; when cover is removed, the switch
opens. The tamper terminals (see Figure 3) should be
connected to the control panel’s tamper loop.

PULSE COUNT OPTION

Each detector includes Pulse Count circuitry that is designed to
provide stability in adverse environments to minimize false
alarms. Two-event pulse count is provided by positioning the
jumper plug across the pulse count pins (see Figure 3 for
location). To select one-event pulse count (instant response),
remove the jumper plug. When programmed for 2-event pulse
count, the detector will signal an alarm within 3 or 4 steps,
since the processing logic requires more complex motion than
just a momentary event. When the detector verifies an
intrusion, the LED will light and the alarm relay contacts will
transfer, both conditions lasting for approximately 1 to 3
seconds (dependent upon signal strength).

To prevent the loss of the plug, we suggest you install it on one
pin when the plug is not in use.

Remedy:

Regular maintenance and inspection (at least annually) by
the installer and frequent testing by the user are vital to
continuous satisfactory operation of any alarm system.
The installer should assume the responsibility of developing
and offering a regular maintenance program to the user, as
well as acquainting the user with the proper operation and
limitations of the alarm system and its component parts.
Recommendations must be included for a specific program
of frequent testing (at least weekly) to ensure the system's
operation at all times.

Locate source and reposition detector if
necessary.

Eliminate source of motion.

Ensure that proper polarity and adequate voltage

is supplied and that wiring is intact (no opens or
shorts) and connections secure.

Determine whether interruption is in protective
loop wiring or at detector's alarm relay contacts.
Disconnect protective loop at detector relay
contact terminals and check continuity across
terminals. If absent at terminals (and proper
voltage is supplied to the detector), return unit for
service. If present, check protective loop wiring.

Remove LED enable/disable plug.

Return unit for service.

Caution customer about layout changes.

THE LIMITATIONS OF YOUR PASSIVE

INFRARED MOTION DETECTOR

While the Passive Infrared Motion Detector is a highly reliable intrusion
detection device, it does not offer guaranteed protection against burglary.
Any intrusion detection device is subject to compromise or failure to warn for
a variety of reasons:

•

Passive Infrared Motion Detectors can only detect intrusion within the

designed ranges as diagrammed in this installation manual.

•

Passive Infrared Motion Detectors do not provide volumetric area

protection. They do create multiple beams of protection, and intrusion can
only be detected in unobstructed areas covered by those beams.

•

Passive Infrared Detectors cannot detect motion or intrusion that takes

place behind walls, ceilings, floors, closed doors, glass partitions, glass
doors, or windows.

•

Mechanical tampering, masking, painting or spraying of any material on

the lenses, windows or any part of the optical system can reduce the
detection ability of the Passive Infrared Motion Detector.

•

Passive Infrared Detectors sense changes in temperature; however, as

the ambient temperature of the protected area approaches the
temperature range of 90° to 105°F (32° to 40°C), the detection
performance can decrease.

•

This Passive Infrared Detector will not operate without appropriate DC

power connected to it, or if the DC power is improperly connected (i.e.,
reversed polarity connections).

•

Passive Infrared Detectors, like other electrical devices, are subject to

component failure. Even though this equipment is designed to last as long

as 10 years, the electronic components in it could fail at any time.
We have cited some of the most common reasons that a Passive Infrared
Motion Detector can fail to catch intrusion. However, this does not imply that
these are the only reasons, and therefore it is recommended that weekly
testing of this type of unit, in conjunction with weekly testing of the entire
alarm system, be performed to ensure that the detectors are working
properly.
Installing an alarm system may make the owner eligible for a lower insurance
rate, but an alarm system is not a substitute for insurance. Homeowners,
property owners and renters should continue to act prudently in protecting
themselves and continue to insure their lives and property.
We continue to develop new and improved protection devices. Users of
alarm systems owe it to themselves and their loved ones to learn about
these developments.

INTERRUPTOR ANTISABOTAJE

El Infrarrojo Pasivo está equipado con un interruptor
antisabotaje para la cubierta. Con la cubierta puesta, el
interruptor está cerrado; cuando se retira la cubierta, el
interruptor se abre. Los terminales antisabotaje (véase Ilust. 3)
deberán conectarse al lazo antisabotaje del panel de control.

OPCION DE CONTADOR DE IMPULSOS

Cada detector incluye un circuito Contador de Impulsos diseñado
para proporcionar estabilidad en entornos adversos minimizando así
las falsas alarmas. El contador de impulsos de dos eventos se
obtiene colocando el puente entre las patillas del contador de
impulsos (véase Ilust. 3 para la ubicación). Para seleccionar un
contador de impulsos de un evento (respuesta instantánea), quite el
puente. Si programa la unidad para 2 eventos, el detector indicará una
alarma a los 3 o 4 pasos, ya que la lógica del proceso requiere un
movimiento más complejo que un sólo evento momentáneo. Cuando
el detector verifica una intrusión, el LED se iluminará y los contactos
del relé de alarma transmitirán, ambas condiciones durante
aproximadamente 1 a 3 segundos (dependiendo de la fuerza de la
señal).

Para evitar perder el puente sugerimos que cuando no lo utilice
lo instale en una de las patillas.
