Beware: in DHF version the DIP switch 2 must be in
the ON position.
Reminder: several DHF sounders can be configured on the same
address; in this case, they will all have the
same programming.
On first start-up, the DHF sounder is
in INIT mode (orange DHF LED (6)
flashing).
Set the Sigma master clock to INIT
mode (see the master clock manual).
Once the receiver is initialised, the
DHF LED is red to begin with and
then green after reception of the DHF
sounder commands from the master clock.
Note: the DHF sounder commands are sent every hour and on each modification of
the programming.
To reset to INIT mode, simply press the TST key for 10 seconds.
Two LEDs indicate the functioning of the system :
- The “~” LED (A) indicates the
presence of the power supply.
- The “Ψ” LED (B) is active during
communication with the master clock.
Green, communication is OK,
Orange and fixed, the Melodys is
just within the limit of DHF range,
reception is uncertain,
Orange and flashing, the Melodys
is in INIT mode,
Red, no DHF sounder commands received.
After the product has been switched on, it waits for an execution order from the
master clock.
