11.5 Function setting menu
This menu allows you to dene allocation of the external input of the mother
board. It depends if you are using the master clock as master or slave unit.
If the master clock is used as master, the external input will, for example,
control circuitry to drive an alarm or buzzer.
If the master clock is used as slave, the external input (terminals 20 and 21)
will detect changes in the alarm output of the master clock used as master.
It can also be used to activate the backlight of the display screen.
To go to the SIGMA function setting menu,
validate the option in the technician menu
with the key,
The following screen is displayed :
The master clock is congured in master
mode by default.
If you congure it in “BACK-UP” (slave) mode
to assign it as a secondary master clock, then the external input (see below)
displays BACK-UP and cannot be modied.
Select a circuit for the external input; the relays proposed are the relays which
have been assigned.
In general, the external input will control a
circuit dedicated to this alarm ringing
function, relay ON ….
A contact connected to the external input can
also control simultaneously several circuits. The circuits to be controlled must
be specied in the PC software. Example: Circuit 1 + Circuit 2 + Circuit 60 +
Circuit 13.
Choosing the mode (START, LENGTH or FORCED ON) allows you to
congure the input for its functioning and the period of functioning in this state.
START: starts the programming of the circuit concerned the rst time it is
pressed and stops it the next time (alarm type message on the display
indicating the external input (circuit 1) and its status (ON, OFF or START).
