ASH Security recently supplied and installed an automatic (three phase) roller shutter for an underground carpark in St Albans.
The customers requirements were for the carpark entrance to be secured with an automated roller shutter system incorporating safety features and a remote control facility for all residents of the building. The type of the motor required for the roller shutter was a direct drive motor due to the multi use aspect and levels of usage.
The curtain had to be quiet yet durable and has been powder coated and foam filled ensuring minimum noise for such a large opening. Some of the key features include automatic closing with time delay, which is fully adjustable. The system can also be linked to access control systems and has the added benefit of a timed maintenance programme which will indicate if an inspection is required sooner than planned due to fault providing maximum safety. ASH Security carried out all the wiring and commisioning on site. We’ll also be providing quarterly maintenance inspections as is required of automatic doors/shutters.
Key safety features include:
- Anti-drop Safety Brake Device
- Stop and return monitored safety beam (infra-red) – the beam detects obstructions and stops operation of the shutter therfore preventing damage or injury
- Safety Edge Device – in addition to the to the infra-red beam, this device has pressures sensors in the bottom rail which stop operation of the shutter upon contact with an object
