Envirograf Manual Set Fire and Smoke Ventilation Grilles

About Manual Set Fire and Smoke Grilles

A manual setting intumescent grille for walls, ceilings, fire doors and ventilation inlets.

Regulations often require fire and smoke protection grilles for openings in fire walls. The Envirograf TJ Grille fulfils this requirement offering full fire and smoke protection. This type is reset by pushing the internal plate back to its original position by means of pen or screwdriver. The plate is held open by an electro-magnet 24V 125mA. Ordering dimensions refer to the internal hole size

The grille can be either installed into an existing 24V fire/smoke alarm system or (alternatively, if there is no alarm system available or the grille is required to be independent), into an Envirograf AC Mains to 24V control unit with smoke detector circuit and N/O or N/C contacts. (This control unit can operate up to 3 grilles).
