Fire Air Grill Type MMS represent passive fire protection, designed with the help of compartmentalization to prevent the spread of toxic gases, smoke and fire. All FGS - Fire Resistant and Cold Smoke Control Mechanical Air Transfer Grill (Type MMS) are designed and certified in accordance with the test criteria’s EIS according to ETAG 026-4. FGS fire air grilles are intended to be embedded into fire partition walls without ductwork. Air Transfer Grilles together with its installation form an inseparable part of fire resistivity rating. Their installation is described in the User Manual of FGS. All FGS fire air grilles can be delivered with either a manual activation or with an actuator.

• Powder coated cover grill for customized look

The product contains galvanized sheet metal, calciumsilicate board, fireproof carbon fiberglass, polyurethanwe foam and ethylene - propylene rubber. These are processed in accordance with local regulations. The product contains no hazardous substances, with the exception of the solder in the thermofuse, which contains a milligram of lead.

By default, all manually operated Fire Air Grills are supplied with manual control, optionally with micro switches. In case of fire, the Fire Air Grill is closed automatically. The Fire Air Grill closes after melting of the thermal fuse. After the closing, the Grill blades are mechanically locked in the closed position and can only be opened manually. Actuating mechanism is activated when the temperature of the air in the duct reaches 72°C and the Fire Air Grill closes within 10 seconds after melting of the fuse.

• ZV Fire Air Grill with an spring return mechanism enclosed into its body, release activated by a fusible thermal link set to 72°C (on demand 100°C).

• DV1 Fire Air Grill with an activation mechanism ZV + closed indication with AC 230 V or AC/DC 24 V contact switch.

• DV1-2 Fire Air Grill with an activation mechanism ZV + open and closed indication with AC 230 V or AC/DC 24 V contact switches.

By default, all actuator operated Fire Air Grills are supplied with actuator with micro switches, optionally with power and communication unit. Fire Air Grill can be equipped with a spring return actuator which closes the damper after the command from the building management system, or after breaching of the thermoelectric fuse. Actuator controlled Fire Air Grills are standardly equipped with thermoelectric fuse, that activates the closing of the damper after reaching or exceeding of ambient temperature of 72°C. Actuator power circuit is interrupted and its spring closes the Fire Air Grill blades within 20 seconds.
