Description

The 55000-885IMC is a sophisticated intelligent detector that operates on the XP95 communication protocol. It contains both an optical (photoelectric) smoke sensor and a thermistor-based heat sensor. The control panel processes the signals from both sensors to provide a more accurate assessment of a fire. This “intelligent” fusion allows the detector to be more sensitive to fast-flaming fires than a standard optical detector, while remaining highly resistant to false alarms caused by steam or transient smoke. As part of the Xpert range, the address is set via a patented coding card in the base, ensuring that replacement heads automatically adopt the correct loop address without manual configuration.

Features

  • Dual-Technology Detection: By monitoring both smoke and temperature, it can detect everything from slow-smoldering PVC fires to intense, fast-burning liquid or wood fires.
  • Xpert Card Addressing: The address is stored in the base using a coded card. This “plug-and-play” capability prevents human error during head replacement and simplifies the commissioning of large systems.
  • Enhanced False Alarm Immunity: The combination of sensors allows the system to distinguish between real fire smoke and non-fire phenomena like steam or dust, which might trigger a single-sensor optical detector.
  • XP95 Digital Protocol: Communicates high-resolution analog values to the fire panel (XFP or ZFP), allowing the panel to make informed decisions based on environmental data.
  • Rate-of-Rise Heat Sensing: In addition to smoke, the thermistor can detect a rapid increase in temperature, providing an extra layer of protection in areas where smoke might be delayed.
  • 360° Alarm Visibility: Features a clear LED that glows bright red during an alarm, ensuring the triggered device can be seen from any direction.
  • Insect-Resistant Chamber: The internal sensing chamber is protected by a fine gauze to keep out insects, which is a common cause of nuisance alarms.
  • Standardized Base Compatibility: Works with the universal 45681-210IMC base, allowing for a consistent installation across different detector types on the same loop
