The manual call point according to EN 54-11 / type A is accommodated in a red plastic housing and is designed for use on the loop with Labor Strauss protocol. The detector is activated by pressing in the plastic pane without breaking it. The pane can be placed again into the idle position with a special key, thereby resetting the detector.
A two-coloured LED indicates the activated condition of the detector in red, the fault condition in yellow and the loop polling in green. The integrated dual-isolator disconnects the loop at short circuit on the loop line.
By means of the Programming Unit FI750/PU, the address of the detector can be set in the range 1 to 240. In addition, the programming unit allows the reading-out of parameters, such as the default analogue value or the production date. Furthermore, in case of connection to a compatible fire detection control panel, the detector can also be AUTO-addressed.
