Description

The 55000-401IMC is a specialized intelligent heat detector for use in high-ambient temperature environments where standard 55°C detectors would cause false alarms. It is classified as an EN54-5 Class CS device, making it ideal for commercial kitchens, boiler rooms, and industrial drying areas where typical operating temperatures can reach up to 55°C. Like the rest of the Xpert range, the loop address is set via a patented coding card in the mounting base, ensuring that the address is tied to the physical location rather than the detector head. This allows for seamless, error-free replacement of heads during maintenance without the need for manual DIL switch setting.

Features

  • High Threshold Safety: Specifically calibrated to reach an alarm state only at 90°C, preventing nuisance alarms in environments that experience extreme, localized heat under normal working conditions.
  • Xpert Card Addressing: The address remains in the base via a plastic “pips” card. When a head is swapped, it automatically reads the address of that specific location, eliminating human error during servicing.
  • Low Airflow Resistance Case: The housing is aerodynamically designed to allow hot air to reach the NTC thermistor quickly, ensuring a prompt response despite the high threshold.
  • Digital Communication: Transmits precise analog temperature data to the fire panel (XFP or ZFP), allowing the system to monitor temperature trends in real-time.
  • Immunity to Smoke/Dust: Because it relies solely on thermal sensing, it is completely unaffected by airborne contaminants like flour, steam, grease, or heavy dust.
  • XP95 Protocol Reliability: Uses a robust digital protocol to ensure error-free communication over long cable runs and in electrically noisy environments.
  • Robust Construction: Made from flame-retardant white polycarbonate, designed to withstand the harsh conditions of plant rooms and industrial zones.
  • Remote Indicator Connection: Features an output terminal to drive a remote LED lamp for detectors hidden in cupboards or ceiling voids.
