Central Office Alarm Interface
The Central Office (CO) alarm interface on the SSC is a DB15 connector that supports three dry-contact (no
voltage supplied) relay switches. Each of the Form C relays is rated to support a maximum switching current
of 1A@30VDC.
The alarm relay contacts should never be connected to high current draw devices, such as sirens or flashing
incandescent lamps.
Caution
The three relays support both normally-open (NO) and normally-closed (NC) devices. For additional
information, refer to the SSC Alarm Cabling chapter for details.
