Technical Specification
The system comprises a heat resistant wire inserted satin weave glass-fibre fabric coloured light grey on a steel roller with integral tubular geared electric motor, gearbox and drive mechanism. Upper limit control by electronic current limiting. Decent by controlled gravity fall via a brake controlled using back-EMF generated from the motor circuit. Lower limit control by extent of fabric.

- Two types of motor available (8 and 30 Nm overall torque)
- Simple controls to receive external fire signals and for testing
- Supplied in partly pre-assembled form for fast installation.
Controls
The fire curtain is capable of operation as an integrated part of the Smoke Control and Fire Management System, usually with emergency power units and the facility to interface directly an OPV addressable control panel (if supplied).
The system is fully protected and fail-safe to avoid the need for fire rated cabling, with 30 minute time delay to maintain units in the raised position in the event of a temporary interruption to the power supply. If power is not returned, units to power descend to down / default position after time delay.
Controls options:
- Simple control box with switches and an indication lamp.
- Smoke detector connected directly to this control box.
- A local control box to be connected to the central fire detection system with a voltage free contact.
- Battery back-up to retain the curtain in its retracted position for a set period if there is mains failure.
