To have the inputs on one Synergis™ unit trigger output relays on other Synergis units (even when some, or none of them are connected to the Access Manager), you must create an I/O zone in Security Center.
An I/O zone allows you to program the I/O linking behavior on multiple Synergis units,
with one unit designated as the master unit. All units must be managed by the same Access
Manager. An I/O zone can be armed and disarmed from Security Desk as long as the master unit
is online.
Configure the I/O zone.
