Produk Selesaiview

The System Sensor 4WTA-B is a 4-wire, photoelectric i3 smoke detector designed for reliable fire detection. It integrates a thermal sensor and a built-in sounder, providing both smoke and heat detection capabilities along with an audible alarm. Its plug-in design simplifies installation, allowing for pre-wiring of the base before the detector is attached.

• Photoelectric smoke detection with integrated thermal sensor.
• Built-in 85dB sounder for audible alarm notification.
• Drift compensation feature automatically adjusts sensitivity to minimize nuisance alarms caused by dust accumulation.
• Smoothing algorithms help prevent false alarms from short-term spikes in smoke or dust.
• Removable detector cover and chamber facilitate easy cleaning and maintenance.

Maklumat Keselamatan Penting

Read all instructions carefully before installation and operation. Failure to follow these instructions may result in property damage, injury, or death. This device must be installed by qualified personnel in accordance with all local and national electrical codes and standards.

• JANGAN CAT the smoke detector. Paint can interfere with the sensor's ability to detect smoke.
• DO NOT MIX with 2112/24AT models.
• Regularly test the detector as per the maintenance section.
• Pastikan kuasa diputuskan sebelum pemasangan atau penyelenggaraan.
• This device is designed for open area protection.

Persediaan dan Pemasangan

The 4WTA-B detector is designed for easy installation. Follow these steps carefully:

1. Pemutusan Kuasa: Before starting any installation, ensure that power to the circuit where the detector will be installed is completely disconnected at the main circuit breaker or fuse box.
2. Lokasi Pemasangan: Choose a suitable location for the smoke detector, typically on the ceiling or high on a wall, away from air vents, fans, and direct sunlight. Refer to local fire codes for specific placement requirements.
3. Memasang Pangkalan:
   

   Figure 4: The detector head detached from its base, revealing the wiring terminals on the base.

   Secure the mounting base to the ceiling or wall using appropriate screws and anchors. Ensure the base is firmly attached. The base allows for pre-wiring.
4. Pendawaian: The 4WTA-B is a 4-wire detector. Connect the wiring from your fire alarm control panel to the terminals on the detector base. Refer to the wiring diagram provided with your specific fire alarm system and the label on the detector base for correct polarity and connections.
   • Typically, two wires are for power (12/24 VDC) and two for signaling.
   • Pastikan semua sambungan selamat dan terlindung dengan betul.
5. Attach Detector Head: Once the base is wired and secured, align the detector head with the mounting base. Gently twist the detector head clockwise until it locks securely into place.
6. Keluarkan Penutup Habuk: If an orange dust cover was used during construction, remove it completely before restoring power.
7. Pulihkan Kuasa: Reconnect power to the circuit. The detector will perform a self-test upon power-up.
8. Ujian Permulaan: Perform an initial test of the detector as described in the "Operating Instructions" section to ensure proper functionality.

Arahan Operasi

The 4WTA-B operates automatically once installed and powered. It continuously monitors for smoke and heat. In the event of an alarm, the built-in sounder will activate, and the detector's LED indicator will illuminate.

Menguji Pengesan

It is crucial to test your smoke detector regularly to ensure it is functioning correctly. Test the detector at least once a month.

1. Ujian manual: Press and hold the test button (if present, typically a small recessed button) on the detector for a few seconds. The alarm should sound, and the LED should flash. Release the button to stop the alarm.
2. Simulated Smoke Test: Use a can of approved aerosol smoke detector test spray. Follow the instructions on the test spray can. Apply a small amount of spray towards the detector's sensing chamber. The alarm should sound within a few seconds.

If the detector does not respond during testing, refer to the "Troubleshooting" section.

Penyelenggaraan

Regular maintenance ensures the longevity and proper operation of your smoke detector.

Pembersihan

Dust and debris can accumulate in the detector's sensing chamber, potentially causing nuisance alarms or reducing sensitivity. Clean your detector at least once a year, or more frequently in dusty environments.

1. Matikan: Disconnect power to the detector at the circuit breaker before cleaning.
2. Remove Detector: Gently twist the detector head counter-clockwise to remove it from its mounting base.
3. Vacuum/Brush: Use a soft brush attachment on a vacuum cleaner to remove dust from the exterior of the detector and around the sensing chamber openings. Alternatively, use a can of compressed air to blow out dust.
4. Lap Bahagian Luar: Lap bahagian luar casing dengan sedikit damp cloth. Do not use cleaning solvents or abrasive materials.
5. Reinstall and Test: Reattach the detector head to the base, restore power, and perform a test as described in the "Operating Instructions" section.

Ujian Biasa

Test the detector monthly using the manual test button or simulated smoke. This confirms the alarm and sensing circuitry are operational.
