Snow Alarm System
Snow Alarm System
SAS-307
The SAS-307 Snow Alarm System is the professional system for continuous and year-round measurement of the current roof load.
In winter, it averts the danger of excessive snow loads and in summer it warns of unnoticed accumulation of water that can build up during heavy rainfall.
Two individually adjustable threshold values trigger a pre-alarm and finally an evacuation alarm depending on the roof load.
Measurement Station
Three measuring stations are attached to the roof surface at selected and exposed points.
This "triple system" provides triple safety in order to recognise different roof loads.
The measuring stations are full of electronics and sensors. They have a measuring range of 5 to 750 kg/m².
The measuring tolerance is 1% of the maximum load. With a diameter of only 50 cm and a weight of 10 kg, they are easy to handle.
Each measuring station is equipped with a pressure equaliser including a positioning rod, which clearly marks the position, even on a snow-covered roof
Control Cabinet
The control cabinet with integrated evaluation electronics is the actual alarm centre of the snow alarm system.
The measuring stations are connected to it.
The measuring stations can be set and the load values of the individual measuring stations can be read via the integrated LCD display.
Optical / acoustic alarm devices can be connected to plug-in switching outputs.
Optionally, the control cabinet can also be equipped with an analogue output to connect the existing building services.
The alarm can also be optionally triggered via a GSM modem, which can be used to alert the relevant persons via SMS.
On request, the control cabinet can also be supplied with remote access via the Internet.
Pre-assembled Control Cables
For easy installation and connection of the measuring stations to the control cabinet, prefabricated control cables with IP 68 connectors are available in lengths of 30 m, 50 m or 100 m.
For larger distances, all cables can be connected and thus extended.
