FireGuard

The Sigrist FireGuard detects emerging fires at their early stages (cold smoke). The sensor uses the available natural air stream in the tunnel. This leads to a greater time for escape and orderly evacuation. (If fog is a potential issue, any influence caused by fog will be eliminated by optional heating elements).  

The sensor is very compact and has no moving parts needs no consumables.  

There are a variety of mounting methods: 

  • Wall 
  • Arched or flat ceiling 
  • Ventilation dampers

Description

Technical Description – Sigrist FireGuard

The FireGuard detects emerging fires already at their early stages (cold smoke). The sensor uses the available natural air stream in the tunnel. Any influence caused by fog will be eliminated by optional heating elements. The sensor is very compact and has neither movable parts nor wear parts nor does it need consumables. As a light source, an economical LED is used.

An adjustable bracket allows mounting at the wall, in the arched section or at the ceiling. Special models for installation in the intermediate ceiling or directly in the ventilation dampers are available. Various ways of connections allow a flexible system integration. Individual setting of parameters allows an optimal object and location related setting of alarms, there are no false alarms.

Maintenance is limited to occasional cleaning and the automatic adjustment with a control rod. Soiling monitoring provides information on the state of the instrument. Maintenance is only necessary when required, from experience only about every 5 years, and the time required per instrument is normally between 15 and 25 minutes at the most.

Sigrist Communication Software

Vx29 is the current software controlling communication between the analyser and the SICON.

Check for updates periodically. Sign up to our newsletter for notifications of software updates.

The control unit SICON uses state-of-the-art touch screen technology with colour display. It allows simple operation using logical menu guidance. The user can select how results are displayed, either as plain values, graphs or historical data, including the indication of system and alarm status.

The control unit SICON offers all possibilities of full system integration using various interface options. A SD card is standard and can be used for data logging with almost unlimited storage capacity.

The SICON is available as a control unit for a single instrument, or the SICON M Control Unit which allows simple operation of several instruments up to a maximum of 8 measuring channels.
