Product description (expand/collapse)
The ROP42 manual call point equipped with the MAR42 module is designed to trigger an alarm by a person who has noticed a fire. ROP42 works in the detection line of the AFS42 control panel. Includes short-circuit isolator.
The principle of operation
Two ROP42 states are recognizable for the MAR42 electronic system: its absence and the alarm state. The MAR42 module has a coded unique address in a given AFS42 system – from 00 to 99. The AFS42 control panel “inquires” three times a second each ROP42 warning device connected to it, receiving in response all operating states and based on them makes decisions resulting from the system configuration. Breaking the glass, and thus pressing the button in the ROP42 call point, causes the sending of an alarm signal, which is treated by the AFS42 control panel as a 1st stage alarm. The ROP42 has a short-circuit isolator system implemented on the printed circuit board MAR42. The status of the isolator is not transferred to the control panel when polling the socket, while the control panel is able to locate which ROP42s have open isolators, based on the information of one-sided ROP42 responses in the loop line. ROP42, where the insulator is open, is powered and “seen” by the control panel from the side where there is no short-circuit.
