Series 13000 is an electromagnetic door release unit in a plastic case for fire doors equipped with a large red release button that can be easily located. 

The door release units of the series 13000 are fitted with a built-in spring release that allows residual magnetic forces to be overcome thus ensuring quick, reliable door release. The circuit includes a dual protection diode against disturbances and polarity reversals. Three lateral inputs are available for the connection of 16 or 20 mm hoses and one back input for cables with a maximum diameter of 10 mm. 

A version is available with the door status control that indicates, with the electromagnet energised, if the door is open (NC type) or closed. Provided with counter-plate. With a suitable bracket, upon request, floor mounting is possible.
