1-9 none Technical alarm with NC contact and activation of the auxiliary channel
Internal siren (MOD 0 or 2) sounds intermittently until one of the following events occurs:
a) there is no longer an alarm;
b) the alarm is reset using the menu of central units with display (with central unit L/N/NT4600/4 press “S”);
c) the reset pushbutton connected to the interface is pressed.
It activates the corresponding auxiliary channel.
1-9 1 Anti-burglary automation with NC contact
It activates the corresponding auxiliary channel without interfering with the status of the burglar-alarm system, therefore without
generating signals or alarms.
1-9 2 Anti-panic alarm with NC contact and activation of the auxiliary channel
Generates a burglar-alarm even with the system switched o and in any division condition. Is silenced with the remote control.

Technical alarm with NO contact and activation of the auxiliary channel
Internal siren (MOD 0 or 2) sounds intermittently until one of the following events occurs:
a) there is no longer an alarm;
b) the alarm is reset using the menu of central units with display (with central unit L/N/NT4600/4 press “S”);
c) the reset pushbutton connected to the interface is pressed.
It activates the corresponding auxiliary channel.
Alarm reset
Gas detector
Note: It is recommended that the GAS sensor and the interface are checked for correct installation and wiring, following the instructions supplied with the sensor itself;
the interface sends the alarm notification within the timescales set for the activation of the alarm repeater.
If a technical alarm is generated upon powering the sensor while the interface is already powered, there is a wiring error in lines + A
