Central alarm panel with direct I/O interface
The interfacing described below applies for central alarm panels that use direct lines for alarm,
mute and acknowledge. For alarm panel using serial interface, refer to “IEC61162-1/2 (NMEA
0183) Devices” on page 79.
From the GN70/MX61x unit we are using the same two wires (red and blue) as for external
alarm relay connection.
Under normal operation you will see 12/24 V between these two wires. In an alarm situation,
or when power is lost, you will see no voltage.
