Sentrol 4300 Series Wireless Smoke Detector

Description

The Sentrol 4300 Series smoke detector requires a Sentrol 4000 RF gateway receiver with Rev J or higher software and a compatible control panel sold separately. To install the detector, the programming guide for the control panel is needed.

Depending on the model, the detector offers features such as:

• CleanMe™ self-diagnostics: Monitors sensitivity and operational status. If the detector drifts out of the UL listed sensitivity range or fails internal diagnostics, its LED extinguishes, and a trouble signal is sent to the control panel.
• Detector/base lock: Discourages unauthorized removal by requiring a screwdriver to detach the detector from its base.
• Optional base tamper: Sends a trouble signal to the control panel when the detector is removed from its mounting base.
• Optional mercury-tilt tamper: Sends a trouble signal to the control panel if the detector is not oriented correctly (upside down and/or horizontal), useful for removable ceiling panels.
• Optional integrated fixed 135°F temperature and rate of rise heat detector: Trips an alarm based on detected temperature.
• Optional low temperature supervision: Sends a low temperature signal when ambient temperature drops to approximately 43°F (6°C). A separate transmitter signal (secondary address) is assigned to a Critical Condition Monitoring (CCM) zone.

Transmitted Signal Outputs: Depending on the model, the detector transmits signals to the control panel including: Alarm, Alarm restore, Tamper, Low battery, CleanMe™, Maintenance alert, Supervisory, and Low temperature supervision.

Selecting a Location

Choosing a suitable location is critical for smoke detector performance. Installation should comply with the National Fire Protection Association's (NFPA) Standard 72. Refer to Figure 2 for placement guidance.

Are More Smoke Detectors Desirable? The required number of smoke detectors may not provide adequate early warning for areas separated by doors from protected areas. Additional detectors are recommended for increased protection in areas like basements, bedrooms, dining rooms, furnace rooms, utility rooms, and hallways. Installation in kitchens, attics, or garages is generally not recommended due to potential for improper operation.

Important: Regulations for smoke detector installations vary by state. Consult your local fire department or authority having jurisdiction for specific information.

Diagram: Figure 2 - Detector Placement. This illustration shows a house floor plan with recommended smoke detector placement. Dots indicate locations for required smoke detectors, and circles with crosses indicate locations for additional detectors for new construction. Areas shown include living room, dining room, kitchen, bedrooms, TV room, and basement.

Installing the Detector

Follow these guidelines in addition to NFPA 72 for optimal performance and reduced false alarms:

• Ceiling-mounted detectors: Place in the center of a room or hallway, at least 4 inches from walls or partitions.
• Wall-mounted detectors: Position the top of the detector 6 to 12 inches below the ceiling.
• Environment: Suitable conditions include temperatures between 40°F (4.4°C) and 100°F (37.8°C) and humidity between 0% and 95% non-condensing.
• Locate away from air conditioners, heating registers, and other ventilation sources that could interfere with smoke entry.
• Mount detectors on a firm, permanent surface. Detectors with a tilt tamper can be mounted on removable ceiling panels.
• Avoid placing detectors near large metallic objects.

Installation Steps:

1. If using the detector/base lock, remove the two knockouts on the mounting base (See Figure 3).
2. Slide the battery compartment cover away from the detector to unsnap and lift it off (See Figure 4).
3. Observe correct polarity and insert the two provided lithium batteries into the compartment. Replace the battery compartment cover.
4. Record the seven-digit ID address from the detector's backside label. This address must be programmed into the RF gateway receiver per the control panel programming guide.
5. For 'L' model detectors, program the "Fire Address plus 1" secondary address into the panel in a separate non-fire CCM non-supervised or 24hr non-supervised auxiliary zone.
6. Program the RF gateway receiver and the control panel according to the control panel programming guide.
7. Remove the red plastic dust cover from the detector.
8. Disconnect alarm notification appliances, service release devices, and extinguishing systems. Test communication between the control panel and each smoke detector before permanent mounting:
   • Press the Test/Silence button on the detector for 2 seconds. A test signal is sent to the control panel.
   • Verify the test signal reception and adequate RF signal strength at the control panel. Relocate and retest if the signal is poor or absent.
9. Mount the base using the provided screws and anchors.
10. Attach the detector to the mounting base: align the raised tab on the detector's lip with the slot on the base. Insert the detector and turn clockwise approximately 15 degrees until it snaps firmly into place. Important: Batteries must be installed for attachment.
11. Test communication between the control panel and each smoke detector:
    • Press the Test/Silence button on each detector for 2 seconds.
    • Verify at the control panel that the test signal was received.
12. Test each detector (refer to "Smoke Testing the Detector") and reconnect all alarm notification appliances, service release devices, and extinguishing systems. Important: Verify control panel alarms and auxiliary functions for a complete system test.

Testing the Detector

Smoke detectors should be tested annually using smoke or canned aerosol simulated smoke. Follow the instructions on the canned smoke or use these steps:

1. Hold a smoldering punk or cotton wick close to the smoke entry openings.
2. Gently direct smoke into the detector for 20 seconds or until an alarm is indicated.

Important: Extinguish the smoke source after testing. The detector LED will remain on while the transmitter sends an alarm signal. The detector sounds a temporal rhythm until the Test/Silence button is pressed. It resets automatically when smoke is no longer present.

Detector Sensitivity Testing

The 4300 Series offers a sensitivity level test mode:

1. Press the Test/Silence button for 2 seconds. The detector performs a test, and the LED flashes one to nine times.
2. Count the LED flashes to determine detector sensitivity status and required action using the table below:

After flashes, if sensitivity is within limits and other tests pass, the detector alarms and resets after 5 seconds. If sensitivity is out of limits or a hardware fault is detected, the LED extinguishes until serviced, and a CleanMe™ or maintenance alert signal is sent.

Understanding the Test/Silence Button

The Test/Silence button performs three functions:

• Testing: Press for 2 seconds for a sounder test (4310 models only), sensitivity test, and sends a test signal to the control panel.
• Silence alarm: Press to silence the sounder during an alarm. The sounder and alarm resume after a few minutes if smoke persists.
• Silence trouble chirp: Press to silence a trouble chirp. The chirp resumes after 24 hours if the condition is not corrected.

Understanding the LED

The LED indicates detector status:

• FLASHING: Every 9 seconds indicates normal operation.
• ON: Detects smoke, sending an alarm.
• OFF: Trouble or maintenance is required; check the control panel for details.

When maintenance is required, the detector's LED extinguishes, and a signal is sent to the control panel:

Fire Prevention and Escape

The purpose of an early warning smoke detector is to detect fires in their early stages and sound an alarm, allowing occupants time to exit safely. No detection device can protect life in all situations; therefore, safeguards should be taken.

Avoid Fire Hazards

• Do not smoke in bed.
• Do not leave children home alone.
• Never clean with flammable liquids like gasoline.
• Properly store materials and maintain good housekeeping to prevent clutter, which can invite fire.
• Use combustible materials and electrical appliances carefully and only for their intended uses. Do not overload electrical outlets.
• Do not store explosive or fast-burning materials in your home.
• Be prepared, as fires can start even after precautions are taken.

In Case of Fire

• Leave immediately. Do not stop to pack or search for valuables.
• In heavy smoke, hold your breath, stay low, and crawl if necessary; the clearest air is usually at floor level.
• If passing through a closed door, feel it for heat. If cool, brace your foot against the bottom, open slightly. If hot air rushes in, slam it shut and latch it. Unvented fires build pressure. Ensure all household members understand this danger.
• Use a neighbor's phone or a street fire alarm box to call the fire department. Leave extinguishing to professionals.

Be Prepared

• Perform fire drills regularly to ensure recognition of alarm signals.
• Draw a floor plan showing two exits from each room. Instruct children carefully, as they may hide during a crisis.
• Establish an outdoor meeting place for everyone to gather during an alarm, preventing anyone from re-entering the house.
• Use window decals to help emergency personnel identify sleeping quarters of children or physically challenged individuals.

Warning! Limitations of Smoke Detectors

Wireless smoke detectors are reliable but may not work under all conditions. No fire detector provides total protection. Smoke detectors are not a substitute for life insurance.

• Detectors require power; they will not operate with dead or improperly installed batteries.
• Unreliable RF signal transmission/reception can occur if the system is not installed, located, serviced, or repaired properly. RF signals may be blocked or reflected by metal objects. Adjacent devices using RF signals may interfere. Test the system often.
• Smoke detectors may not be heard by sound sleepers or those under the influence of drugs or alcohol. Closed doors and distance can block sound. This detector is not designed for the hearing impaired.
• Detectors may not activate early enough. They only activate when sufficient smoke reaches them. Fires starting in chimneys, walls, roofs, behind closed doors, or on different levels may not trigger an alarm if smoke does not reach the detector.

SMOKE DETECTORS ARE A SIGNIFICANT HELP IN REDUCING LOSS, INJURY AND EVEN DEATH. HOWEVER, NO MATTER HOW GOOD A DETECTION DEVICE IS, NOTHING WORKS PERFECTLY UNDER EVERY CIRCUMSTANCE AND WE MUST WARN YOU THAT YOU CANNOT EXPECT A SMOKE DETECTOR TO ENSURE THAT YOU WILL NEVER SUFFER ANY DAMAGE OR INJURY.
