Connecting The Relays - Enterasys I Series Hardware Installation Manual

Connecting the Relays

Connecting the Relays
There are two fault relays, a primary and a secondary. The primary relay can be used to monitor
the power supply and a software-configurable selection. The secondary relay does not monitor
power. It must be configured by the software, as described in the Enterasys I-Series CLI Reference
Guide.
Each relay has two contacts, where contact 2 is on the side that opens when a fault is detected. By
default, both relays are in a closed state and open when an alarm is present. Both alarm relays can
be changed to an open state and closed when an alarm is present. For more information about
changing the alarm relays from normally closed to normally open, see
from Normally Closed to Normally
Ensure the equipment that is to be attached to the relays falls within the range of the relay
specifications, as provided in
You must use 14 to 20 AWG solid copper wire for all ground, power, and relay connections.
Refer to
To connect your alarm system to the relays:
1. Make sure the wires (14 to 20 AWG solid copper, customer-provided) are stripped to 0.25 inch
(6.3 mm) + 0.02 inch (0.5 mm). Stripping more can leave exposed wire from the connector.
2. Insert the wire into the primary relay contact 1 (right side), as shown in
screw to secure the wire.
3. Repeat for contact 2 (left side).
4. Repeat the previous steps for the secondary relay.
