3.1 FACTORY PROGRAMMING

Siren options are programmable through a series of cutting-wire jumpers, that can be identified with letters "A"
to "N".
Jumper Function
A, B Sound time-out
C Input type
D Input reference
E Alarms count
F Scaffolds function
G, H, I, L Sound mode
M,N not used

3.2 SOUND TIME OUT PROGRAMMING

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.
Programming is performed through jumpers A and B, according to the table.

3.3 INPUT TYPE PROGRAMMING

This function allows programming BL and TC inputs, of the normally closed or
balanced types (6K8 +/- 5%).
Programming is performed through jumper C, according to the table.

3.4 INPUT REFERENCE PROGRAMMING

This function allows programming the reference of BL and TC inputs to positive or
negative.
Programming is performed through jumper D, according to the table.
