8.5.5. CASE 5 – drive of an electric lock and an opening buzzer
Case expected to automatically repeat the activation of the relay1 (typically door opener) also on relay2 so it is
possible to connect to the second relay a device to signal the successful opening of the gate. For example, to a
warehouse where workers assume responsibility to pay attention to an adequate buzzer that indicates the effective
opening of the passage. The device drived by the AA-560 relay2 provide to notify (for the time of activation of the
relay1) that a person is entered in the warehouse. Automatically, every time a gate is opened, is carried out an alert
for the warehouse employees. TB3 is designed for use only contact relay2, the system is powered on TB4, on TB1
connects the electric lock and on TB2 the telephone line.
In this example the programming settings for the management of the relays could be:
the relay1 set as “Electric lock”, the relay2 set as “After relay 1” with a very short delay to immediately notify the
activation of relay1 door opener and with a duration (activation time of the relay 2) useful for the duration of the
desired buzzer sound.
