Daily use

Daily use is very simple:
Use prox card and then enter the code.

Configure / Change User Codes

P [b or s] [yyy] [k] [z] [e] P or
b=programcode, s=systemcode (8 digits)
yyy = address
k = hold prox card in front of SA850 (successful read is acknowledge with beeps)
z = user code (def. in 'Code length')
e = max usage (if none entered there are no limits)
Finishing:
P: Code is configured as an A-code (Access but only if by-passed)
: Code is configured as an AB-code (Access and By-pass)
If further codes must be configured the procedure can continue with yy.
If configuration is done terminate with P or

Delete user codes

Reset to factory settings

Reset to factory settings following below steps:
1: Disconnect power supply and network wires
2: Connect Pink wire (buzzer) to Black wire (ground)
3: Re-connect power and wait 5 sec until red LED lights up
4: Release Pink wire (buzzer) from Black wire (ground) within 5
sec.
SA850 is now reset to factory settings and all codes are cleared.
