Key Specifications/Special Features

Four Style B (Class B) Initiating Device Circuits (IDCs).All zones accepSocket & Outlet t two-wire smoke detectors and any normally-open contact devices.One built-in, Style Y (Class B) Notification Appliance (Signal) Circuits (NACs).Alarm, Trouble and Supervisory, Form-C relays standard.24-volt operation.Resettable four-wire smoke detector power @ 500 mA.Non-resettable power @ 500 mA.One-man walk-test programmable for silent or audible test.Disable/Enable control per IDC.Reverse polarity protection.An automatic fire alarm system-typically made up of smoke detectors, heat detectors, manual pull stations, audible warning devices, and a fire alarm control with remote notification capability-can provide early warning of a developing fire.
Such a system, however, does not assure protection against property damage or loss of life resulting from a fire.
The Manufacturer recommends that smoke and/or heat detectors be located throughout a protected premise following the recommendations of the current edition of the National Fire Protection Association Standard 72 (NFPA 72), manufacturer's recommendations, State and local codRubber Machinery es, and the recommendations contained in the Guide for Proper Use of System Smoke Detectors, which is made available at no charge to all installing dealers. A study by the Federal Emergency Management Agency (an agency of the United States government) indicated that smoke detectors may not go off in as many as 35% of all fires. While fire alarm systems are designed to provide early warnEnvironment Protection Device ing against fire, they do not guarantee warning or protection against fire. A fire alarm system may not provide timely or adequate warning, or simply may not function, for a variety of reasons:
Smoke detectors may not sense fire where smoke cannot reach the detectors such as in chimneys, in or behind walls, on roofs, or on the other side of closed doors. Smoke detectors also may not sense a fire on another level or floor of a building. A second-floor detector, for example, may not sense a first-floor or basement fire.
Particles of combustion or "smoke" from a developing fire may not reach the sensing chambers of smoke detectors be- cause:Barriers such as closed or partially closed doors, walls, or chimneys may inhibit particle or smoke flow.Smoke particles may become "cold," stratify, and not reach the ceiling or upper walls where detectors are located.Smoke particles may be blown away from detectors by air outlets.Smoke particles may be drawn into air returns before reaching the detector.The amount of "smoke" present may be insufficient to alarm smoke detectors. Smoke detectors are designed to alarm at various levels of smoke density. If such density levels are not created by a developing fire at the location of detectors, the detectors will not go into alarm.
Smoke detectors, even when working properly, have sensing limitations. Detectors that have photoelectronic sensing chambers tend to detect smoldering fires better than flaming fires, which have little visible smoke. Detectors that have ionizing-type sensing chambers tend to detect fast-flaming fires better than smoldering fires. Because fires develop in different ways and are often unpredictable in their growth,neither type of detectoris necessarily bestand a given type of detector may not provide adequate warning of a fire.
Smoke detectors cannot be expected to provide adequate warning of fires caused by arson, children playing withmatches (especially in bedrooms), smoking in bed, and violent explosions (caused by escaping gas, improper storage of flammable materials, etc.).
Heat detectors do not sense particles of combustion andalarm only when heat on their sensors increases at a predetermined rateor reaches a predetermined level. Rate-of-rise heat detectors may be subject to reduced sensitivity over time. For this reason, the rate-of-rise feature of each detectorshould be tested at least once per year by a qualified fire protection specialist. Heat detectors are designed to protect property, not life.
importANT! must be installed in thesame room as the control panel and in rooms used by the system for the connection of alarm transmission wiring, communications, signaling, and/or powerWoodworking Machinery . If detectors are not so located, a developing fire may damage the alarm system, crippling its ability to report a fire.
Audible warning devicessuch as bells may not alert peopleif these devices are located on the other side of closed orpartly open doors or are located on another floor of a building. Any warning device may fail to alert people with a disability or those who have recently consumed drugs, alcohol or medication. Please note that:Strobes can, under certain circumstances, cause seizures in people with conditions such as epilepsy.Studies have shown that certain people, even when they hear a fire alarm signal, do not respond or comprehend themeaning of the signal. It is the property owner's responsibility to conduct fire drills and other training exercise to make people aware of fire alarm signals and instruct them on the proper reaction to alarm signals.In rare instances, the sounding of a warning device can cause temporary or permanent hearing loss.A fire alarm system will not operate without any electrical power. If AC power fails, the system will operate from standby batteries only for a specified time and only if the batterieshave been properly maintained and replaced regularly.
Equipment used in the systemmay not be technically compatible with the control. It is essential to use only equipment listed for service with your control panel.
Telephone linesneeded to transmit alarm signals from a premise to a central monitoring station may be out of service or temporarily disabled. For added protection against telephone line failure, backup radio transmission systems are recommended.
The most common causeof fire alarm malfunction is inadequate maintenance. To keep the entire fire alarm system in excellent working order, ongoing maintenance is required per the manufacturer's recommendations, and UL and NFPA standards. At a minimum, the requirements of Chapter 7 of NFPA 72 shall be followed. Environments with large amounts of dust, dirt or high air velocity require more frequent maintenance. A maintenance agreement should be arranged through the local manufacturer's representative. Maintenance should be scheduled monthly or as required by National and/ or local fire codesSwitch and should be performed by authorized professional fire alarm installers only. Adequate written records of all inspections should be kept.
