Hyfire HFI-TA-05 Analogue Category P Thermal Detector - Altair Series

General Description

The Hyfire HFI-TA-05 is an Analogue Category P Thermal Detector from the Altair Series. It continuously samples temperature variations in a protected area to provide early fire warnings with a high level of false alarm rejection. Designed for open area protection, it connects to control panels using the Altair analogue-intelligent addressable communication protocol, ensuring efficient information exchange and rapid responses.

Note: Before installation, thoroughly read this leaflet and consult applicable European Standards and National Codes of Practice (e.g., BS5839-1:2002 for UK) for guidance on location, spacing, and use. Seek advice from compatible control panel instructions for appropriate design and configuration.

[Diagram: Figure 1 shows the Hyfire HFI-TA-05 detector unit.]

Installation

The detector must be mounted on compatible adaptor bases listed in the "Technical Specifications" table. Refer to the specific base's literature for detailed installation instructions.

Wiring

After installing the base to the ceiling, wire it to connect to the analogue loop. Ensure analogue loop wires are correctly connected to the base's terminals as shown in the wiring diagram.

[Diagram: Figure 2 illustrates the wiring connections for the analogue loop, showing terminals for LOOP IN (+), LOOP IN (-), LOOP OUT (+), LOOP OUT (-), and SHIELD.]

Remote Output Capability

This detector features remote output capability, allowing a remote indication lamp or a compatible sounder to be wired to the base terminals (Figure 3). If connecting other equipment to the remote output, its supply current may need to be limited using an adequate resistor. Consult the "Technical Specifications" table and assess the external device's current absorption.

[Diagram: Figure 3 shows the connection points for REMOTE ALARM (+) and REMOTE ALARM (-).]

Short Circuit Isolators

The detector is equipped with bi-directional short-circuit isolators designed to prevent loop failure due to wiring faults. In case of a short circuit, isolators on either side will open, maintaining most functions. Normal operation can be restored after the fault is corrected.

Device Programming

Address Setting

Detectors can be addressed using a special hand-held programming unit or automatically by the control panel (if supported). Addresses can range from 1 to 240, with each device on the loop requiring a unique address.

Thermal Sensitivity Setting

Two thermal sensitivity levels are available: Rate Of Rise (ROR) A1R category (most sensitive) and BS category (least sensitive), compliant with EN 54 part 5. Sensitivity can be selected via a hand-held programming unit or directly through the control panel, if supported.

Detector Placement

1. Position the detector centrally on its adaptor base, ensuring it is level.
2. Rotate clockwise with gentle pressure; the detector will seat into its keyed location.
3. Continue rotating clockwise a few degrees until fully engaged in the adaptor base.
4. When firmly engaged, check the alignment of the raised reference marks on the detector and base (Figure 5).

[Diagram: Figure 4 shows the detector being rotated onto its base.]

[Diagram: Figure 5 illustrates the alignment of reference marks for correct detector placement.]

Important Notes on Detector Placement

• Disconnect loop power before installing the detector.
• Dust covers protect devices during shipping and initial installation but do not offer complete protection against contamination. Remove detectors before construction, major re-decoration, or other dust-producing work. Ensure dust covers are removed before the system is made operational.

Anti-Tamper Detector Lock

The detector can be locked to its base to deter unauthorized removal. To enable this, remove the anti-tamper plastic detail using a cutter (Figure 6). To unlock, insert a screwdriver tip into the side slot of the base with light pressure and turn anticlockwise to release the detector (Figure 7).

[Diagram: Figure 6 shows the removal of the anti-tamper plastic detail.]

[Diagram: Figure 7 illustrates the process of unlocking the detector with a screwdriver.]

LED Indicators

The detector features dual LEDs that indicate status:

• Green: Blinking indicates normal operative status.
• Red: Indicates an alarmed condition.
• Amber: Indicates a fault condition (if supported by panel software).

LEDs are managed by the control panel, and green blinking can be disabled by the installer. The positioning of these LEDs is shown in Figure 8.

[Diagram: Figure 8 shows the location of the dual LEDs on the detector.]

Identification Tab

The adaptor base includes a plastic tab for displaying identification data. Detach the tab, write or label the required information, and then insert it back into the base's slot.

[Diagram: Figure 9 shows the identification tab on the base.]

Testing the Detectors

Heat Test

Use a 1000-1500 W hair dryer or an approved heat tool. Direct heat towards the detector from the side, holding the source approximately 15 cm away to prevent cover damage. The detector should trigger an alarm message to the control panel, and its red LED should activate.

Magnet Test

Position a test magnet next to the detector's raised mark and move it 45 degrees anticlockwise (Figure 10). This simulates heat on the thermistor, verifying electronic circuits and control panel communication. The detector should trigger an alarm message and activate its red LED.

[Diagram: Figure 10 illustrates the magnet test procedure.]

Preliminary Note: Detectors should be tested after installation and annually. After each test, reset the system and allow one minute for power stabilization.

Maintenance

Before performing maintenance, isolate and disable the system to prevent accidental alarms or faults. Remove the detector from its base for inspection. Use a small, soft bristle brush, vacuum tube, or clean, dry compressed air to remove contaminants from the thermistor area. Wipe the exterior housing with a clean, damp, lint-free cloth. After inspection, reposition detectors, re-apply power, and test operation.

Warnings and Limitations

Hyfire devices use high-quality components resistant to environmental deterioration. However, after 10 years of continuous operation, replacement is advisable to maintain performance. Ensure this device is used only with compatible control panels. Fire detection systems require regular checking, servicing, and maintenance.

Smoke detectors may respond differently to various smoke types; seek application advice for special risks. Detectors may not respond correctly if barriers exist or if affected by special environmental conditions. Always refer to and follow national codes of practice and recognized fire engineering standards. Conduct appropriate risk assessments initially and update them periodically.

Warranty

All devices are supplied with a limited 5-year warranty against faulty materials or manufacturing defects, effective from the production date. This warranty is voided by mechanical or electrical damage caused by incorrect handling or usage. Products must be returned via an authorized supplier for repair or replacement, with full problem details. Full warranty and returns policy details are available upon request.

Certifications and Compliance

The detector is certified by LPCB (928a/02) and complies with European standards EN 54-5:2017+A1:2018 and EN 54-17:2005. It is suitable for use in compatible fire detection and alarm systems and is classified under Category A1R and BS (category P).

Certifications include CE and UKCA markings (HF-20-007CPR, HF-20-007UK).
