Context UL-Plus Ionisation Smoke Detector, 58000-550IMC

The Context Plus 58000-550IMC ionisation smoke detector uses a low-activity radioactive foil to ionise the air in the smoke chamber and cause a current flow. Smoke entering the chamber reduces the current, which leads to an alarm.

It belongs to the Context UL-Plus range of high-specification intelligent detectors with the Discovery protocol, supplied as the head only and fitted to the 45681-210IMU UL-Plus base with an XPERT card.

Key features:

• Discovery communication protocol with distributed intelligence: decisions are made in the detector head as well as at the panel.
• Five response modes to suit changing environments.
• Drift compensation for constant sensitivity in dirty or dusty areas.
• Resists steam and cigarette smoke.
• Stores site-specific data in the detector.
• Alarm flags for fast alarm reporting.
• Conventional alarm facility during a panel processor fault.
• 360° alarm indication with flashing LED option.
• Patented XPERT card addressing.
• UL listed.

Typical applications:

• Projects specifying UL-listed ionisation detection, subject to local regulations on radioactive sources.
