About Automatic Set Intumescent Fire and Smoke Grilles

Regulations often require fire and smoke protection grilles for openings in fire walls.

The Envirograf TJ Grille fulfils the requirement offering full fire and smoke protection. This type resets itself and has a permanent loading of 24V 125mA, with the solenoid to open the grille taking 24V 8A for 1 second.

Can be reversed for closed then to open.

This grille can be wired to a 24V alarm system. Alternatively, an Envirograf mains to 24V control unit can be used to control up to 8 manual reset grilles or 3 automatic reset grilles.

The control units have N/O and N/C contacts to wire to the existing fire alarm or optional smoke detector.

Ordering dimensions refer to the Internal Hole size.
