Electric Activation

Automatic smoke vents can be supplied with an electric Thermolatch® to allow the vents to be operated by a smoke detector or fire alarm control panel. In addition to electric automatic smoke vent latch activation, these vents feature fusible link activation and provisions for manual operation. Electric latches can be supplied for 115 VAC, 24 VAC, 220 VAC, and 24V DC power requirements.

Explosion Release

BILCO Type SV and Type DSH automatic smoke vents can be equipped to operate as explosion release vents or as combination fire/explosion vents. Explosion release smoke vent latch options are designed to limit structural damage to a building in the event of an explosion by releasing internal pressure. Explosion release mechanism (shown) is preset and factory-tested to release at between 25-30 pounds per square foot (122-146 kg/m2) of pressure on the underside of the covers. (Lumivents and Type ACDSH models are not available with explosion relief latches.)

Motorized Operation

All BILCO commercial products can be supplied with electric motor operation to open and close covers with the push of a button. Motor operation provides a convenient means of ventilating work areas in manufacturing facilities. Product is supplied with built-in motor operator, push button control station (shown) and wiring diagram.

Manual Winch Operation

Roof hatches and automatic smoke vents can be supplied with manual winch operation to open and close covers remotely. Winch operation provides a convenient means of ventilating work areas in manufacturing facilities and is a less expensive alternative to electric motor operation. Product is supplied with manual winch and wall mounting bracket (cable and additional pulleys can be supplied at additional cost).

Curb Option-Curb Liner

This metal insulation roof hatch curb liner is made of the same material as the curb and capflashing. This option is also available as a smoke vent curb liner. It is ideal for applications where aggressive adhesives or torch applied weather proofing systems are being used.

Curb Option-Fully Enclosed

This fully enclosed curb Insulation liner is made of the same material as the curb. This option replaces the capflashing. This option is available as a fully enclosed roof hatch curb and a fully enclosed smoke vent curb. It can be used with hot applied roofing systems or where the hatch or vent is welded directly to the roofing panel.

Curb Option-Built-in Louvers

BILCO roof hatches and smoke vents can be supplied with louvers built into their curb. A roof hatch curb with built-in louvers provides continuous building ventilation. BILCO louvered roof hatch curbs and smoke vents are equipped with a standard insect screen. In some areas, smoke vent curbs with built-in louvers are required in vents over elevator shafts to meet elevator-shaft code requirements.

Curb Option-Fully Enclosed with Apron

The design of this fully enclosed roof hatch curb with apron allows the hatch top be easily installed on top of existing concrete, wood, or metal curbs. This curb is also available as a fully enclosed smoke vent curb with apron. It is ideal for situations where the roofing material is applied prior to the hatch or vent arriving on-site.

Curb Option-Modification for Metal Roofs

Base flanges of all BILCO roof hatches and smoke vents can be fabricated with built-in configurations for most brands of metal building roof panels. Our roof hatch curbs for metal roofs and smoke vent curbs for metal roofs offer simplified installation. All metal roof curbs include a built-in self-drainage feature that eliminates water accumulation on the up-slope side.

Security Burglar Bars

For high security applications, BILCO automatic smoke vents can be supplied with burglar bars to prevent unauthorized building entry. Burglar bars are 3/4” (19 mm) in diameter and are welded in place in the smoke vent opening. Bars are typically welded at 6” (1.52 cm) and 12” (3.05 cm) on center and are available on both steel and aluminum smoke vents.
