4.2 DESCRIPTION OF THE INPUTS
IN1 and IN2 ALARM INPUTS
• There are 2 single-shot alarm inputs.
• They can be programmed as N.O. - N.C . - TERMINATED or NOT USED (see “Instal-
lation menu”).
• The inputs can be programmed individually as 24h/24h (always active and instanta-
neous) or subjected to ON status of the communicator (TC command, see IN3).
• An input subjected to ON status (AND TC) can be programmed as INSTANTANEOUS or
TIMED (5sec./15sec./30sec./60sec./90sec).
IN3 INPUT (TC)
• IN3 input is configured as a TC (Trigger Control) command. It can be programmed as
N.O., N.C. or TERMINATED. IN1 and IN2 switching will not be recognised and the alarm
communication procedure will not be activated if level +12Vdc (TC ON) is present on
IN3. If on the other hand the level is 0Vdc (TC OFF), the switching of inputs IN1 and IN2
will generate a cycle of telephone calls. This operation can be useful if the communicator
is connected to an Elkron alarm control unit with a TC programmed output that by
default provides a high level (+12V) when the system is off and a low level (0V) when it
is active. Connect input IN3 to output TC of the Elkron control unit to automatically
enable/disable alarm transmission according to the active/inactive status of the control
unit.
• A later transition from ON to OFF of the TC command, i.e. following a new activation of
the system, will cause the “alarm memory” to be cleared.
• NOTE: Conventionally, condition 0V = TC OFF and +12V = TC ON is provided when
the TC input is programmed as N.O. (normally closed).
4.3 DESCRIPTION OF THE OUTPUTS
U1 and U2 FAILURE OUTPUTS
• These electrical outputs are dedicated to signalling FAILURES. They normally output a
+12Vdc signal, which is down when the output is signalling. Two types of failures are
controlled, namely “TECHNICAL FAILURES” and “TELEPHONE FAILURES”.
• Output U1 is dedicated to “technical” failures. It switching indiscriminately for:
- Blackouts or external power supply under the minimum stated value for longer than 2
hours (terminals 6 and 7).
- Low battery, i.e. power under a threshold of 10.8Vdc for longer than 120 seconds.
Blackout/power back and low battery events are managed in the following way:
1. Blackout: the “MAINS/BATTERY” LED on the front panel goes out after approximately
10 seconds. After a 2 hour time-out, U1 switches to blackout and makes the techni-
cal failure calls to the voice enabled telephone numbers.
2. Power back: the “MAINS/BATTERY” LED lights up after approximately 10 seconds
and U1 is reset. No calls are made.
3. If the battery power drops under the 10.8V threshold, the “MAINS/BATTERY” LED will
blink, the U1 output will switch to low battery and the technical failure calls will be
made. U1 will be reset when power comes back but the “MAINS/BATTERY” LED will
continue blinking to indicate that the low battery event has been detected. This LED is
switched of manually by clearing the System Status menu memory. Note that low
battery status can only be detected during a blackout.

Output U2 is dedicated to “ telephone failures ” and indiscriminately switches in the follow-
ing cases:
