Firex Smoke Alarm

Understanding Smoke Alarm Types

The photoelectric type alarms are generally more effective at detecting slow, smoldering fires which smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.

The ionization type alarms are generally more effective at detecting fast, flaming fires which consume combustible materials rapidly and spread quickly. Sources of these fires may include flammable liquids or paper burning in a waste container.

Both types of alarms are designed to provide adequate detection of both types of fires. For the benefits of both systems, consider installing smoke alarms that combine both photoelectric and ionization sensing technologies.

Important Safety Information

WARNING: This smoke alarm requires constant 120-volt AC power AND a working 9-volt battery to operate. It will NOT function if AC power is interrupted or the battery is removed, drained, or improperly connected.

• Use only the specified battery type.
• Do not connect this alarm to other types of alarms or devices not listed in this manual.
• DO NOT remove or disconnect the battery or turn off AC power to quiet unwanted alarms; this removes your protection. Open windows or fan air to silence.
• Test the Push-to-Test button weekly. Do not use open flames for testing.
• Smoke alarms must not be used with detector guards unless evaluated and found suitable.
• Installation should be performed only by a licensed, qualified electrician, adhering to all local and national electrical and building codes.
• This alarm is NOT intended as the PRIMARY protection for buildings requiring full fire alarm systems (e.g., hotels, hospitals). It may be used as SUPPLEMENTAL protection in individual rooms.
• Install a smoke alarm in every room and on every level for maximum protection. Smoke may not reach an alarm in time if a fire starts in a remote area or behind closed doors.
• Interconnected alarms ensure all units sound when one detects smoke. Do not interconnect alarms between different living units.
• Smoke alarms may not alert all household members (e.g., due to noise, deep sleep, hearing impairment). It is the responsibility of household members to assist those who may not be awakened by the alarm or who cannot evacuate safely.
• Alarms detect combustion particles, not heat, flame, or gas. They warn of developing fires but may not provide quick enough warning for fast-burning or explosive fires.
• Smoke alarms have limitations and are not foolproof. They are not warranted to protect all lives or property. They are not a substitute for insurance. Test weekly and replace every 10 years.

Smoke Alarm Placement

Invensys Controls Americas recommends complete coverage by installing a smoke alarm in every room. The National Fire Protection Association's (NFPA) minimum requirement (Standard 72) states:

• Install outside each separate sleeping area, in the vicinity of bedrooms, and on each additional story (including basements, excluding crawl spaces/unfinished attics).
• In new construction, if multiple detectors are required, they should be interconnected so that any alarm triggers all others.

The NFPA also recommends additional detectors for areas separated by doors from required areas, including basements, bedrooms, dining rooms, furnace rooms, utility rooms, and hallways not otherwise protected.

The California State Fire Marshal recommends early warning detection in all rooms and areas, including sleeping areas, living rooms, dining rooms, bedrooms, kitchens, hallways, attics, furnace rooms, closets, utility rooms, basements, and attached garages.

For best protection, install a smoke alarm in every room. Interconnect all alarms.

Placement Guidelines for Different Home Types:

• Typical Efficiency Home (Apartment): Install on the ceiling or wall closest to the sleeping area.
• Typical Mobile Home: For homes built before 1978, install on an inside wall between 4 and 12 inches from the ceiling, especially if the ceiling has poor insulation or extreme temperatures. Install inside each bedroom and in the hallway outside each sleeping area.
• Typical Single-Story Home: Install on the ceiling or wall inside each bedroom and in the hallway outside each sleeping area. If a hallway is over 30 feet long, install at each end. If there is a basement, install on the basement ceiling at the bottom of the stairwell.
• Typical Two-Story or Split Level Home: Install on the ceiling or wall inside each bedroom and in the hallway outside each sleeping area. If a hallway is over 30 feet long, install at each end. Install at the top of a first-to-second floor stairwell. If there is a basement, install on the basement ceiling at the bottom of the stairwell.

Key for Placement Diagrams:

• A solid circle symbol represents a standard Ionization Smoke Alarm.
• A triangle symbol represents an Ionization Smoke Alarm with False Alarm Control or a Photoelectric Smoke Alarm.

Important Smoke Alarm Placement and Exception Information:

• Install as close to the center of the ceiling as possible. If not practical, mount no closer than 4 inches (0.1m) from a wall or corner.
• If local codes allow, install on walls between 4 and 12 inches (0.3m) from ceiling/wall intersections.
• Install a minimum of two smoke alarms in every home.

Specific Placement Rules:

• Partial Walls: Install in rooms divided by partial walls (at least 24 inches down from ceiling or up from floor).
• Peaked, Cathedral, or Gabled Ceilings: Install 3 feet (0.9m) horizontally from the highest point.
• Attics: Install in lived-in attics or attics housing electrical equipment (furnaces, air conditioners, heaters).

DO NOT Install Smoke Alarms:

• Near appliances or areas of normal combustion (kitchens, near furnaces, hot water heaters). Use specialized alarms with unwanted alarm control for these areas.
• In areas with high humidity (bathrooms, near dishwashers/washing machines). Install at least 10 feet (3 meters) away.
• Near air returns or heating/cooling supply vents. Install at least 3 feet (0.9 meters) away, as air currents can blow smoke away from the detector.
• In rooms where temperatures are below 40°F (4°C) or above 100°F (38°C).
• In extremely dusty, dirty, or insect-infested areas, as loose particles can interfere with operation.

Interconnecting Smoke Alarms

• This smoke alarm can be interconnected with up to 11 other Firex models (FADC, AD, ADC) or up to 6 Firex ADH heat alarms, for a total of 18 interconnected devices. Do not connect to other types or models of smoke alarms.
• Connect smoke alarms to a single AC branch circuit. If local codes require, ensure the neutral wire is common to both phases.

Red and Green LED Indicators

False Alarm Control (Model ADC)

Model ADC features a False Alarm Control that quiets unwanted alarms for up to 15 minutes. To use, press and release the test button during an unwanted alarm. The alarm should stop within ten seconds, indicating it is in False Alarm Control mode.

If the alarm does not enter False Alarm Control or resounds, the smoke level may be too high, requiring emergency action.

Testing the Smoke Alarm

WARNING: Test each smoke alarm after installation and periodically to ensure proper operation. Do not use open flames for testing.

• Test smoke alarms weekly and upon returning from extended absences.
• Stand at arm's length when testing; the alarm horn is loud.

Weekly Test Procedure:

1. Observe the green LED: A constant green light indicates AC power is present.
2. Firmly depress the Push-to-Test button for at least five (5) seconds. The alarm should sound three short beeps, followed by a 2-second pause, repeating. The alarm may sound for up to 10 seconds after releasing the button.
3. For interconnected systems: All smoke alarms should sound within three seconds after the test button is pushed on the tested unit.
4. If the alarm does not sound, turn off power, check wiring, and retest.

If the Push-to-Test function does not operate properly, replace or return the alarm for repair.

DANGER: If the alarm horn sounds when not being tested, the alarm is sensing smoke and requires immediate attention and action.

If the smoke alarm sounds and you are not testing it, it indicates a dangerous situation requiring immediate response. Develop and practice family escape plans.

• Ensure everyone understands the alarm sound and its meaning.
• Determine two exits from each room and an escape route to the outside.
• Teach household members to feel doors for heat and use an alternate exit if a door is hot. Instruct them NOT to open hot doors.
• Teach household members to crawl along the floor to stay below smoke, fumes, and gases.
• Determine a safe meeting place outside the building.

What to Do in Case of a Fire

1. Stay calm.
2. Leave the building quickly. Feel doors for heat before opening; use an alternate exit if necessary. Crawl along the floor and do not stop to collect belongings.
3. Meet at a pre-arranged outdoor meeting place.
4. Call the fire department from outside the building.
5. DO NOT go back inside a burning building. Wait for the fire department.

Following these guidelines can help in a fire. Practicing fire safety rules and preventing hazardous situations reduces the chance of fires starting.

Troubleshooting

DANGER: Always turn off power at the main fuse box or circuit breaker before troubleshooting.

WARNING: Do not disconnect battery or AC power to quiet an unwanted alarm; this removes protection. Fan air or open a window to remove smoke or dust.
