Manual call point MHA 108.132V0 is a device intended for manual fire signalling by a person discovering the fire. It is used in FDFAS for railway wagons and on conventional (non-addressable) loops with voltage characteristics.
Manual call point MHA 108.132V0 is a conventional (non-addressable) detector. It is used in indoor areas where permanent movement of persons is expected or where the use of automatic detectors is ineffective (staircases, halls, etc.). Manner of use is given by the picture under the device’s cover glass .After breaking the glass and pressing the button it sends an impulse to the control panel. Manual call point connects to conventional loops of railway control panels and to conventional loops with voltage characteristics of conventional control panels MHU 106 (with loop module JSM-5), MHU 108, MHU 113 and to loop modules on control panels MHU 115 and MHU 116/117.
The detectors comply with ČSN EN 54-11 standard and are subject to conformity assessment according to Act No. 22/1997 Sb., as amended by Act No. 71/2000 Sb. and relevant government regulations.
