2. Postavljanje i instalacija

The NH-200 thermal sensor is designed for straightforward installation. Ensure all local and national electrical codes are followed during installation. This device is intended for use with compatible fire alarm control panels.

2.1 Raspakivanje

Carefully remove the NH-200 sensor and B300-6 base from its packaging. Inspect for any signs of damage. Do not install damaged components.

2.2 Mounting the Base (B300-6)

1. Position the B300-6 base on the desired mounting surface (e.g., ceiling or wall).
2. Secure the base using appropriate screws through the designated mounting holes. Ensure the base is firmly attached and level.
3. Connect the system wiring to the terminals on the B300-6 base according to the fire alarm control panel's wiring diagram. Pay close attention to polarity.

2.3 Attaching the Sensor

1. Align the NH-200 sensor with the mounted B300-6 base.
2. Gently push the sensor onto the base and rotate it clockwise until it clicks into place. This secures the sensor and makes the electrical connection.
3. Verify that the sensor is securely seated and cannot be easily removed without intentional rotation.

2.4 Uključivanje

Once the sensor is installed and wired, power on the fire alarm control panel. The sensor will perform a self-diagnostic check upon initial power-up. Refer to your control panel's manual for specific power-up sequences and indications.

3. Principi rada

The NOTIFIER NH-200 is a fixed-temperature thermal sensor. It is designed to activate an alarm when the ambient temperature at the sensor location reaches or exceeds 135°F (57.2°C). This sensor operates as part of a FlashScan fire alarm system, providing reliable temperature monitoring.

3.1 Indikacija alarma

Upon detecting a temperature of 135°F or higher, the sensor will trigger an audible alarm through the connected fire alarm system. The specific alarm sound and system response are configured at the fire alarm control panel.

3.2 Normalan rad

Under normal operating conditions, the sensor continuously monitors the ambient temperature. There are no user-adjustable settings on the sensor itself. Its operation is entirely passive until the fixed temperature threshold is met.

4. Održavanje

Regular maintenance ensures the continued reliable operation of your NH-200 thermal sensor. It is recommended to follow a routine inspection and cleaning schedule.

4.1 Čišćenje

Dust and debris can accumulate on the sensor over time, potentially affecting its performance. To clean the sensor:

1. Carefully remove the sensor from its base by rotating it counter-clockwise.
2. Use a soft, dry cloth or a vacuum cleaner with a brush attachment to gently remove dust from the exterior of the sensor. Do not use liquid cleaners or solvents.
3. Reattach the sensor to its base, ensuring it is securely locked in place.

4.2 Testiranje

Periodic testing of the thermal sensor is crucial to confirm its functionality. Consult your fire alarm system's documentation for specific testing procedures. Typically, this involves using a heat source (e.g., a hairdryer on a low setting, held at a safe distance) to raise the temperature around the sensor until it activates. Always notify relevant personnel before conducting tests to avoid false alarms.

4.3 Zamjena baterije

The NH-200 sensor is powered by the fire alarm control panel and does not contain user-replaceable batteries. If the system indicates a power issue with the sensor, consult a qualified technician.

5. Otkrivanje problema

This section addresses common issues you might encounter with the NH-200 thermal sensor.

5.1 Sensor Not Responding / No Alarm

• Provjerite ožičenje: Ensure all wiring connections to the B300-6 base are secure and correctly terminated according to the system's wiring diagram.
• Provjerite snagu: Confirm that the fire alarm control panel is powered on and providing power to the sensor loop.
• Sensor Seating: Make sure the sensor is properly seated and locked onto its base. Remove and re-attach the sensor if necessary.
• Sistemska greška: Check the fire alarm control panel for any fault indications related to the sensor or its zone.
• Prag temperature: Ensure the ambient temperature has actually reached or exceeded 135°F.

5.2 Lažni alarmi

• Faktori okoline: Identify if the sensor is located near a heat source (e.g., heating vents, direct sunlight, industrial equipment) that could cause temperatures to exceed 135°F under normal conditions.
• Kontaminacija senzora: Dust or debris on the sensor can sometimes interfere with its operation. Refer to the cleaning instructions in Section 4.1.
• Kvar sistema: If false alarms persist without an apparent cause, there may be an issue with the fire alarm control panel or wiring. Consult a qualified fire alarm technician.

For persistent issues not resolved by these steps, contact a certified fire alarm system technician or Notifier technical support.
