3.1 PROGRAMMING

Siren options are programmable through a series of cutting-wire jumpers, that can be identified with letters "A"
to "N".

3.2 SOUND TIME OUT PROGRAMMING (A,B)

This function allows programming the maximum delay after which, should
the block signal go on missing, the siren automatically stops (useful function
in case of cable cutting).
The siren will generate a new alarm cycle with a following lack of the block
signal.
NOTE: The standards EN50131-4 do not allow for alarm time settings
longer than 15 minutes.

3.3 INPUT TYPE PROGRAMMING (C)

This function allows programming AL and S inputs, of the normally closed or
double-balanced types (6K8 +/- 5%).
NOTE: To ensure compliance with the standard EN50131-4, for grade 3, the inputs AL and S must be of
the double-balancing type; if NC inputs are used (jumper cutting), the siren switches to grade 2).

3.4 INPUT REFERENCE PROGRAMMING (D)

This function allows programming the reference of AL and S inputs to positive or
negative.
NOTE: When double-balanced type inputs are used, it is recommended to
power the siren off +13.8V or refer the inputs to negative.
