Description
The technical alarm interface is used to receive signals from the outside (normally
analogue signals, like the closing/opening of a contact), converting them into digital
information for the BUS.
This information gives the possibility of differentiating between alarm notifications,
like the activation of the siren, or the telephone dialler, or the closure of the gas/water
solenoid valve.
The functions described can be obtained using a dedicated communication line between
the devices of the burglar alarm system, called auxiliary channel.
Up to 9 auxiliary channels are available for each system.
They are assigned by configuration of the device(s).
Technical data
Power supply from SCS BUS: 27 Vdc
Max. absorption: 6 mA
Operating temperature: 5 – 40 °C
Legend
1. Clamp for burglar alarm BUS
2. Configurator socket
3. Line activated LED
4. External sensor connection clamp
5. Traditional external sensor connection clamp
6. Reset pushbutton connection
Configuration
The technical alarm interface module requires the allocation of the progressive number
within the group of auxiliary devices (relay actuator and auxiliary channels interface),
the auxiliary channel number, and the operating modes.
N°
This configurator assigns the progressive number inside the auxiliary unit.
Configurator 1 identifies the first auxiliary, configurator 2 identifies the second and so on
for a maximum of 9 auxiliaries.
AUX and MOD
In combination the configurators in the AUX and MOD sockets assign the operating mode
on the basis of the following table.
Dimensional data
Size: 2 Basic modules
Congurators
Description
AUX MOD
none none Technical alarm with normally closed (NC) contact
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.
none 2 Anti-panic alarm with normally closed (NC) contact
Generates a burglar-alarm even with the system switched o and in any division condition.
Is silenced with the remote control.
none 4 Technical alarm with normally open (NO) contact
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.
Activation from the technical alarm interface
Relay actuator: F481 and 3479
