SGG STADIP® PROTECT with alarm wire
Besides the optimum burglar-resistant characteristics of SGG STADIP® PROTECT laminated glass, further
protection is obtained by providing the panes with alarm systems. Wire loops burnt into the pane or alarm wire
inserted between the glass and the interlayer set off an alarm if the wire is broken, due to the pane being damaged.
An electrically conducting silver wire is laid in meander fashion on the interlayer between two panes of a SGG
STADIP® PROTECT unit. If the pane is damaged and the wire torn an alarm is set off. The connection resistance
depends on the size of the pane. SGG STADIP® PROTECT with alarm wire has been tested by the German
Association of Property Insurers (VdS) and approved under licence no. G 181104.
CHARACTERISTICS
Wire insert
- fine silver wire, 0,1 mm thick
- resistance approx. 1,75 Ω/m
- maximum current load 0,5 Amp.
The temperature induced resistance change is 0,004 Ω/Kelvin, that means, for the application in question the total
pane resistance can fluctuate upwards and downwards by a maximum of 10% due to temperature variations.
If higher electrical resistance or a greater breaking sensitivity of the alarm wire is desired, it is possible to replace
the fine silver wire by other materials. Please inquire.
Wire pattern
The wire runs in parallel lines with a normal spacing of 35mm. However, other wire spacings outside the scope of
the VdS approval are technically possible. Due to the low tensile strength of the alarm wire and the greater number
of interlayers within SGG STADIP® PROTECT, fitted with an alarm wire, it is possible, that deviations from the
parallel, may occur.
Examples of the wire patterns and positions of connection points viewed from outside
Surface fixed alarm wire (ADF)
The connection sockets are situated on the room side on the visible surface of the pane at a distance of 35mm from
the edge of the glass. The connection wires are 30mm to 50mm long and must not be shortened.
The connections sockets must be protected by the PVC protective scaps supplied. The caps must be slid over the
connection wires emerging from the pane and pressed into the hole. The connection wires must be protected by a
flexible insulating tube, one end of which is pushed into the protective cap.
Edge-fixed-alarm wire (ADR)
The connection wires are situated in the rebate area. The glass unit has no protruding parts resulting from the
connection. Glazing must be performed in accordance with our guidelines. This also applies to the connection of the
alarm signalling system. You will find the relevant information in the Technical Information – Glazing instructions.
