AIN TECHNICAL SPECIFICATIONS
1.2.1
The Product ensures:
a. sound and light signaling if connected alarm is triggered;
b. sound alarm disabling (mute);
c. light alarm disabling if the alarm is switched off on the connected equipment;
d. in case of failure (malfunction) alarm is actuated by forming a voltage level on
the alarm circuit contacts (valid only for AU-106);
e. in case of failure (malfunction) alarm is actuated by dry contacts closing (open-
ing);
f. AU-206 additionally ensures a connection of external signaling unit with 24 V
DC power supply.
