The GfS DEXCON® offers a simple and cost effective solution to reduce the abuse of emergency exits. Adopting the universally recognised “no entry” sign, the GfS DEXCON® is a visually effective deterrent which is supported by an acoustic alarm of 90 dBs. The GfS DEXCON® is completely self-contained and easy to install. It offers a wide range of electronic features to configure the product to the specific needs of the customer. The GfS DEXCON® is also available for application with panic bars, push bars and multipoint locking systems. Whilst most of the features are identical for each of these applications, the GfS DEXCON® for panic bars and push bars have an integrated pre-alarm. Ultimately, in the event of an emergency, means of escape can also be obtained by exiting via the emergency exit door.
