System carries enhanced “S” designation for smoke seal when installed with guides and additional smoke protection.

General Description:

The fabric curtain is manufactured from X32K woven glass fibre cloth incorporating a “Panama” weave for increased stability the fabric has a nominal weight of 540g/m² and is tested to withstand temperatures of up to 1000°C for a period of 60 minutes.

The active roller assembly, incorporating the fabric, is housed in galvanised mild-steel head box which is normally bolted to the fabric of the building. The curtain head box is manufactured from 1.2 mm galvanised steel, the enclosure is rated at the same temperature as the curtain fabric. Removable cover plates are incorporated to allow access to the curtain rollers. Standard head box sizes are 150mm x 150mm for single.

Larger head boxes may be required where the curtain drop is in excess of three metres. A suitably weighted bottom bar is provided to prevent deflection and ensure correct operation under gravity upon receipt of a signal from the fire alarm panel or total mains and battery failure. Various oversize assessments have been conducted.

A polycarbonate extrusion is supplied as standard, this locates into the profile formed in the bottom of the box. The roller is constructed from an octagonal tube, each of which incorporates a 24volt d.c. motor & gearbox and a sealed heavy duty ball bearing assembly. A motor control circuit housed in a steel enclosure is mounted onto the motor end of the head box.

Control system:

Operation of the curtains is via the Group Control Panel which can either be mounted adjacent to the smoke curtain head box within the ceiling void, allowing access for maintenance, or mounted in a remote position from the curtain.

The panel requires a local 230v ac supply rated at 3 amps via an un-switched fused spur on a maintained supply installed by others. For operational purposes the G.C.P. must be connected to a normally-closed volt-free contact within the fire alarm control panel configured to open on fire and fail safe.

Each control panel is capable of operating up to six rollers and includes battery back-up which will maintain the curtains in their retracted position for a period of three hours during a mains failure. It is also possible to manually operate the curtains during this period.

Should the battery voltage fall below a predetermined limit, a low voltage cut off circuit will activate the curtain, which will descend in a controlled manner under the force of gravity.

The roller motors, which are 24 volt d.c., must be wired from the G.C.P. in a ring main using suitably sized cable to ensure a voltage of 24v d.c -10%.

The curtains descend upon receipt of a signal from the fire-alarm panel and retract when the signal is removed. During ascent the motors are controlled via a synchronised speed circuit to ensure all curtains are raised at similar rates. In the event of mains and battery backup failure, the curtains descend under the force of gravity.

Limit switches are not used to control the upper and lower positions of the curtain. There is a manual key operation from GCP to facilitate override and testing.

Optional Extras:

Split drop delay: An optional braking system is available to allow a two stage descent during gravity deployment. This provides partial descent to a predetermined level to permit preliminary escape and initial smoke containment. After delay the barrier descends to its full operational position.

Voice warning: Audio or spoken multi message facility.

Obstruction warning: A beam detector which will sound in the event of any obstruction being placed in the curtain drop line.

Visual alert system: Standard localised light or strobe light.

Emergency retract: Manual operation to momentarily retract for occupant escape and emergency service access.

Walk through escape: A push-through overlap to provide means of passage through the barrier once deployed.

Others: Other variants are available such as manual reset, curtain decals and signage and delayed descent.
