Install Stratix 5410 Switches Chapter 4
Wire the External Alarms The switch has four alarm inputs and one Form C (single-pole, double-throw)
alarm output relay circuits for external alarms. The input alarm relay circuits
are designed to sense if the alarm input is open or closed relative to the alarm
input reference pin. The output alarm relay circuit has one Form C relay, with
one normally open (NO) and one normally closed (NC) contact. You can
configure the output alarm relay as either normally energized or normally de-
energized by using the CLI.
See Appendix D for an alarm wiring example.
Alarm signals are connected to the switch through the 8-way alarm relay RJ45
connector. Five connections are dedicated to the four alarm input circuits:
• Alarm input 1
• Alarm input 2
• Alarm input 3
• Alarm input 4
• Common
An alarm input and the common wiring connection are required to complete
one input alarm circuit. You must provide either an NO or an NC dry contact
to complete the alarm circuit between common and one of the four alarm
inputs.
The three remaining connections for the Form C output alarm circuit are as
follows:
• NO output
• NC output
• Common
An alarm output and the common wiring connection are required to complete
one output alarm circuit. The Form C output alarm relay provides one NO
and one NC dry contact.
ATTENTION: Do not apply an external voltage source to the alarm inputs.
Limit alarm output wiring to 48 V DC, 0.5 A.
ATTENTION: Wire connections to the power and relay connector, must be
UL- and CSA-rated, style 1007 or 1569 twisted-pair copper appliance wiring
material (AWM) wire.
