Simon Security System 43
Option 53: Hardwire Siren Supervision
(Default = off)
Determines whether the panel monitors hardwired 
sirens for open conditions (on), or not (off).
If this option is turned on, sirens connected to the 
panel terminals require an EOL resistor in the wire cir-
cuit (see “Installing the System” for siren wiring). If 
this option is turned off, EOL resistors are not required 
whether sirens are connected or not.
Note  
For UL listed systems, this feature must be on and EOL 
resistors installed. Also for UL Listed systems, this feature 
must be on if Option 29: Panel Piezo Alarms is off.

Option 54: Access Code Length
(Default = 4)
Determines how many digits are in all access codes.
Turning on this option lets you set the access code 
length to 3, 4, 5, or 6 digits. Turning off this option 
resets the access code length to the default setting, 
resets Master, Utility 1, and Utility access codes.
Read the following before changing this option.
• This option affects all system access codes (Mas-
ter, Utility 1, Utility 2, Panic, and User).
• Changing the access code length changes the 
Master, Utility 1, and Utility 2 access codes to 
their respective defaults as described in the table 
below.
Note  
Changing the Access Code Length clears/deletes any 
User Codes that were previously programmed. If the cus-
tomer wants the Access Code Length changed, it should 
be set before programming any new (unprogrammed) 
access codes, whenever possible.
