MAINTAINING PROPER OPERATION

In order to maintain the detector in

proper working condition, it is important

that the following be observed by the

user.

1. Power should be provided at all

times. Loss of power to the unit will

result in the alarm contacts reverting

to an alarm state.

2. Units should never be re-aimed or

relocated without the advice or

assistance of the alarm service

company.

3. The physical surroundings of the

protected area should be changed. If

furniture or stock is moved, or air-

conditioning or additional heating is

installed, the system may have to be

readjusted by the alarm service

company.

4. Walk-tests should be conducted

frequently (at least weekly) to

confirm continued proper coverage

by each detector.

TO THE INSTALLER

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

insure the system's operation at all

times.

THE LIMITATIONS OF THIS PASSIVE INFRARED MOTION DETECTOR

While the Intrusion 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 creat 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 mirrors, 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 32° to 40°C, the detection performance can decrease.

• This Passive Infrared Detector will not operate without appropriate DC power connected to it, or 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 they are

designed to last as long as ten years, the electronic components 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 one eligible for lower insurance rates, 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.

TROUBLESHOOTING

Locate source and reposition detector.

Eliminate source of motion.

Assure that proper polarity and adequate voltage is supplied and that wiring is intact (no opens or shorts) and connection

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 present, check protective loop wiring. If absent

at detector terminals (and proper voltage is supplied to the detector), return unit for service.

Return unit for service.

Caution customer about layout changes. Reposition detector.

Mount on secure surface.

TROUBLESHOOTING

Comprobar si existen calefactores eléctricos ó de gas, exposición ante llamas, arcos eléctricos etc. Localizar la fuente y

reposicionar el detector. Ajustar la posición del espejo.

Eliminar la fuente de movimiento.

Asegúrese de que el voltaje suministrado y la polaridad del mismo, es el apropiado y que el cableado esté intacto (que no

esté abierto ó en corto) y las conexiones bien seguras.

Determinar si la interrupción está en el cableado del bucle de protección ó en los contactos del relé de alarma del detector.

Desconectar el bucle de protección de los terminales de los contactos del relé del detector y comprobar la continuidad, a través de

los terminales. Si es corrects, comprobar el cableado del bucle de protección. Si no hay continuidad en los terminales del detector

(y el voltaje suministrado al detector es el apropiado), devolver la unidad para su reparación.

Comprobar si los terminales del LED están rotos ó cortados. En tal caso, devolver la unidad para su reparacion.

Prevenir al cliente acerca de la disposición de los cambios. Reposicionar el detector.

Montar en una superficie segura.

Identificare la sorgente di calore e riallocare l'unità. Regolare il puntamento dello specchio.

Eliminare la causa del movimento.

Controllare che la tension e la polarità siano quelle corrette e verificare se i cavi di collegamento sono interrotti o in cortocircuito.

Verificare se l'interruzione é nel cablaggio o sui contatti del relé. Scollegare i conduttori e controllare la chiusura dei contatti

del relé. Se funzionanti, controllare il cablaggio. Altrimenti sostituire l'unità.

Rispedire l'unità per la riparazionie.

Informare il cliente sulle cause dell'anomalia. Spostare il rivelatore.

Montare l'unità su una superficie stabile.
