Physically larger than the Stopper, the Stopper II® is a unique device which has been helping stop false fire alarms around the world for more than 20 years, without restricting legitimate operation of devices such as fire alarm break glass call points.

It is ideal for schools, colleges, hospitals, nursing homes, hotels and public buildings of almost every kind where there is a history or a threat of false alarms.

The cover can pivot on the cable hinge giving full access to the device it's covering without being misplaced.
