For single, double and multiple glazing assemblies
This particular Safe-T-Punch™ product application is intended for OE fitment and is only suitable for fitment during the manufacturing of a double glazed emergency window.
Energy conservation is a recognised and important global issue. Energy is expensive, by saving energy we improve our environment. Controlling the occupied climatic environment inside a vehicle or building by using air conditioning is standard practice. These appliances consume energy. In order for the climatic control system to be effective, openings such as windows and doors are limited to the minimum. As part of efficient insulation against energy loss, double glazing or even triple glazing window assemblies are used in buildings, buses, trains and marine craft.
The above factors result in a situation where emergency egress from such an environment may become difficult.
The Safe-T-Punch™ STP50F and STP40F device combination for double or multiple glazing emergency window assemblies is designed to provide functional emergency exit safety comparable with the functionality of homologated single glazed Safe-T-Punch™ equipped readily breakable emergency windows. By using approved STP50/40 devices, the double glazed emergency exit conforms to UN ECE R107 Emergency Window requirements for M2 and M3 type vehicles.
The 9mm low profile of the STP40F device allows for fitment in the airgap of a double or multiple readily breakable safety glass window assemblies with a minimum airgap of 10mm. Larger airgaps are easily accommodated.
By fitting the combination Safe-T-Punch™ STP50/40F, a fully compliant emergency exit device is provided on each layer of readily breakable safety glass. These low profile devices, are fitted directly in- line with each other, on the window glass, during the manufacturing and installing of the emergency window assembly. This alignment allows for the devices to act independently or collectively when operated by hand in an emergency. A single hit by hand often has sufficient energy to destroy both panes of readily breakable safety glazing in one attempt.
Only the primary STP50F device is fitted to the cabin/room’s emergency window’s interior surface, accessible to the occupants. This device is equipped with an environmental protection ring that resists vandalism and theft of the device, and is secured against unintentional activation by use of a safety tag.
The secondary STP40F device is fitted on the secondary window pane’s interior facing surface; in the airgap between the readily breakable safety glass panes readable from the inside of the room/ passenger cabin.
The STP40F Secondary device is installed first, during OE manufacture of the double glazed emergency window unit. This device and operating instructions are installed in-line with the intended fitment location of the primary device. The secondary STP40F device is not fitted with a safety tag so as to be ready to operate collectively when the primary interior window is broken. This secondary device is protected against unintentional activation by it being placed in the sealed airgap between the panes. It is not accessible until the glass of the primary emergency window has been broken. This installation provides long term protection to the secondary device and the instructions sticker against vandalism and cleaning wear n’ tear.
The STP50F Primary device is installed last; after completing fitment of the double glazed emergency window assembly to the vehicle, boat, train or building. Installing the STP50F as the last step ensures good in-line installation alignment of the two devices. This makes provision for collective operation of the installation.
