GNA42

GNA42
Addressable socket

Nest addressed GNA42 equipped with a module MAR42 is intended for the fastening and addressing fire detectors OSD23. Jack works in the line of regulatory control box AFS42. Contains a short circuit isolator.

The principle of operation

GNA42 socket equipped with a module MAR42 powers and controls the State of detector wpiętej in the slot. For an electronic circuit MAR42 are recognizable three United States Watch: its lack of surveillance and alarm status, status. MAR42 module has a unique address encoded in the system AFS42-from 00 to 99. Control unit AFS42 three times per second "query" each receptacle attached to it in response all three States detectors and on their basis shall take the decisions arising from the configuration of the system. Socket GNA42 has made on the printed circuit layout MAR42 short circuit isolator. The status of the insulator is not passed to the PBX when querying the slot, while the control unit is able to locate which slots have opened insulators based on information partial responses slots in the loop line. Detector stuck in the slot in which the opening is an insulator is powered and "seen" by switching from this page in which there are no short circuits.
