The Honeywell smoke sensor Filtrex as available from IDTek is well-suited for areas where dust particles may hinder early smoke detection and may also cause false alarms. The Filtrex smoke sensor has a protective casing for the smoke sensor compartment to prevent false alarms. It is well-suited for any area where heat sensing may be the only alternative to early fire detection. The Honeywell Filtrex smoke sensor draws air into a chamber where particles and mist are removed. The smoke level is assessed through a sensor and communicated through a line to the control panel system. IDTek incorporates various Honeywell Life Safety products to ensure maximum building protection against fires. Various other Honeywell products are also available through us.
