+12V DC voltage supply
0V DC voltage supply
Strobe control (with 0V DC in case of alarm)
Siren control (with 0V DC in case of alarm)
Tamper relay output
potential-free
NC=normal state (normal closed)
NO=tamper (normal open)
Battery fault relay output, potential-free
NC=normal state (normal closed)
NO=battery fault
Red lead to battery
Black lead to battery
Battery fault transistor output
+12V = normal state
0V = no battery connected or
+12V DC voltage supply
(If the voltage supply is not restored with 6h, the
siren + strobe are activated for 30s.)
0V DC voltage supply
Tamper transistor output
0V
open / high impedance = tamper
Strobe control 0V DC in case of alarm
(strobe is active when 0V DC signal is present)
Siren address 0V in event of alarm (siren is active is
0V DC signal is present, but only for max. 3 min)
