Ex manual alarm call point
[Type dC31]
The manual call point, type dC31, was developed for explosion hazard areas, where gas or dust can cause an explosive atmosphere. The device provides a maximum security, without using a safety barrier. According to a free choice of different resistors, at a threshold alarm system, the detector can be used at several fire alarm systems. The impact resistant chassis is available on stock in five different colours. The easily replaceable glass panel consist of flat, colourless thin sheet glass.
