Code Lock
The electronic lock connected to 2N® Helios can not only be activated by the phone
but also directly from the door using the keypad. In this mode, the keypad behaves
like a standard code lock with the following features:

Both switches can be controlled (if 2 connected)

Password length - 1 to 16 digits;

Up to 10 passwords per switch;

Switch activation time - 1 to 9 seconds;

Acoustic switch activation signalling – continuous tone.
The code lock uses the same passwords as the ones that have been defined for the
telephone based switch control. Remember that the default passwords (
00 for switch
1 and 11 for switch 2) cannot be entered from the numerical keypad because they are
notoriously known.
Control
Enter the correct password and . If the password is valid, a long tone is transmitted
for a predefined time (5seconds by default). The corresponding switch is activated
during this time. If the password is invalid,
2N® Helios sends a refusal signal.
