Description
DESCRIPTION
The Chemelex RAYCHEM SBS-XX-SNR control panel for pipe frost protection of sprinkler systems provides a totally integrated solution for the control of RAYCHEM self-regulating heating cables for sprinkler applications. The control panel comprises multi-control and multi-sensor thermostatic control and redundant circuit automatic switching capability in order to be compliant with the requirements of BS EN 12845:2008. The SBS-xx-SNR panels can switch 2-12 circuits of frost protection heating cables with up to 12 control and sensor inputs (1 per “prime” circuit and redundant circuit). The panel also includes electrical circuit protection devices (C-type circuit breakers and RCD protection) for safety and peace of mind. The panels need only be connected to the 400Vac (3 phase) supply.
ADVANTAGES
Fast connection of multiple circuits directly into the control panel
• No need for additional connections or junction boxes
– 2-12 maximum circuit lengths can be connected to 1 panel
– Automatic redundant circuit switching as required by BS EN 12845:2008
– Circuit protection and safety devices integrated into the panel
• No need for separate safety devices
– Digital temperature feedback for each individual sprinkler line
– Alarm function in case of heater failure (and automatic switch to redundant line)
– Complete system from the manufacturer
• System and components specifically selected for high performance frost protection of sprinkler systems
