Notifier FST-951 Fixed Temperature Thermal Sensor User Manual

1. Производ је готовview

The Notifier FST-951 is a fixed temperature thermal sensor designed for integration into fire alarm systems. This device detects heat exceeding a predetermined threshold, triggering an alarm condition. It utilizes FlashScan Technology for efficient communication within compatible Notifier systems. The sensor is housed in a white casing, suitable for various indoor environments.

2. Инсталација и подешавање

Installation of the Notifier FST-951 thermal sensor should only be performed by qualified personnel in accordance with all local and national electrical codes and standards, including NFPA 72. Proper placement is crucial for effective fire detection.

2.1 Монтажа

1. Ensure the mounting location is clean, dry, and free from obstructions that could impede heat detection.
2. Attach the compatible sensor base (not included) securely to the ceiling or wall using appropriate fasteners.
3. Connect the system wiring to the terminals on the sensor base as per the wiring diagram provided with the base and control panel documentation.
4. Align the FST-951 sensor head with the mounting base and rotate clockwise until it clicks into place, ensuring a secure electrical connection.

2.2 Почетно укључивање

Once installed, apply power to the fire alarm control panel. The sensor will perform a self-diagnostic check. Refer to the control panel manual for specific power-up sequences and indicator lights.

3. Операција

The Notifier FST-951 is a fixed temperature thermal sensor, meaning it activates when the ambient temperature at the sensor location reaches a specific, predetermined threshold. It does not detect smoke or rapid temperature changes (rate-of-rise) unless specified by the model variant.

• Нормалан рад: Under normal conditions, the sensor continuously monitors the ambient temperature. There are typically no visible indicators (like flashing LEDs) during normal operation for this specific model, as it is a thermal sensor head. Communication with the control panel occurs via FlashScan Technology.
• Стање аларма: If the temperature at the sensor reaches its fixed activation point (e.g., 135°F or 155°F, depending on the specific model variant), the sensor will enter an alarm state. This alarm condition is communicated to the fire alarm control panel, which will then initiate its programmed alarm sequence (e.g., activating audible/visual alarms, notifying monitoring stations).
• Ресетовање аларма: After an alarm condition, the sensor will remain in alarm until the temperature drops below the alarm threshold and the fire alarm control panel is reset. Refer to your control panel's manual for proper alarm reset procedures.

4. Одржавање

Regular maintenance ensures the continued reliability and proper functioning of your thermal sensor. Always follow NFPA 72 guidelines for inspection, testing, and maintenance of fire alarm systems.

4.1 Чишћење

• учесталост: Inspect the sensor head annually for dust, dirt, or obstructions. More frequent cleaning may be required in dusty environments.
• Процедура:
  1. Notify relevant personnel that the fire alarm system will be temporarily taken out of service to prevent false alarms.
  2. Carefully remove the sensor head from its base by rotating counter-clockwise.
  3. Користите меку, дamp cloth to wipe the exterior of the sensor. Do not use harsh chemicals or abrasive cleaners.
  4. Уверите се да влага не улази у унутрашње компоненте.
  5. Reattach the sensor head to its base, ensuring it is securely seated.
  6. Restore the fire alarm system to normal operation and verify proper communication with the control panel.

4.2 Тестирање

Functional testing of thermal sensors should be conducted periodically by trained professionals. This typically involves applying a controlled heat source to the sensor to verify its activation at the specified temperature. Consult NFPA 72 and local codes for testing frequency and methods.
