Profile: Cooper Fulleon Ltd. is a manufacturer of alarm signaling devices. We produce life saving audible and visual units. Our door retainers are simple to install and robust. They are ideal for a wide range of applications such as hospitals, schools and industrial premises. Our retainers enable the doors to be held open under normal conditions but to automatically release in the event of a fire alarm evacuation. Our anti-tamper sounder provides a monitoring facility which can give a warning if the sounder is removed from its base. This anti-tamper facility can be supplied fitted to the sounder or as module which can be mounted during installation. Our sounder includes a wide operating voltage and rugged construction. Our warning beacons are available in three different light sources, rotating mirror beacons, xenon flash tube beacons available with single or double flash and LED beacons. Signal tower is supplied in modular form with a base unit (terminal element) & separate bayonet-fit lens or sounder. These may be used to warn the potential hazards or indicate the status of plant items & doors.
