Electrical Characteristics
Each of the three dry-contact relay switches is rated to support a maximum switching current of 1A@30VDC.
The relay contacts should not directly connected to high current devices such as sirens and flashing lamps.
The CO alarm interface of the SPIO is suitable for connection to intra-building or unexposed wiring or
cabling only. This interface MUST NOT be metallically connected to interfaces that connect to the outside
plant (OSP) or its wiring. This interface is designed for use as an intra-building interface only (Type 2 or
Type 4 ports as described in GR-1089-CORE, Issue 5) and requires isolation from the exposed OSP
cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces
metallically to OSP wiring.

Central Office Alarm Wiring Example
The following figure depicts how the dry-contact relays can each control up to two external alarm indicators.
In this example, the CO alarm interface is connected to a CO Alarm Panel, where green LEDs are wired to
indicate normal operation, and red LEDs are wired to indicate an alarm condition.
