Menu 2 - System Options 
System options are used to configure system wide options, such as time and 
dates, system timers and maintenance. 
The following submenus describe the features associated with Menu 2 – System 
Options.

The ZeroWire system clock can manage day, time, time zone, and day light 
saving time settings to ensure ongoing accurate time.

time and date automatically with an Internet Time Server if configured in Menu 6

General Options 
Panel Zone Doubling 
If enabled, the two (2) hardwired zone inputs will be doubled to support four (4) 
zones. The terminals for Zone 1 will represent zones 1 and 3, and the terminals 
for zone 2 will represent zone 2 and 4. This option cannot be selected for zones 
other than the two zones on the main panel. This option cannot be used in 
conjunction with the DEOL option. 
Panel Box Tamper 
The ZeroWire has a built-in normally closed tamper switch that will sound the 
siren if the ZeroWire is removed from the wall. This option will enable or disable 
this tamper switch. 
System Zone Tamper 
If enabled, the ZeroWire will monitor all zones except fire zones for Dual End of 
Line. A short or open circuit on a DEOL will activate zone tamper alarms. This 
feature cannot be used if Panel Zone Doubling is enabled. 
Enable Celsius Scale 
Disable Hardwired Zones 
If enabled, the ZeroWire will disable all hardwired zone inputs. Wireless zones 
with zone numbers 1 to 16 may still be used.
