Alarm Ports
The switch contains two alarm ports: One for alarm input and one for
alarm output. Each alarm port contains three contact points.
The alarm ports use RJ-45 connectors. To connect either the alarm input
or alarm output, use 24 to 18 AWG cable properly rated for the
deployment environment. The maximum length of an alarm cable is two
meters.
An alarm cable must be contained within the cabinet (for cabinet
applications), or within the building. Do not expose an alarm cable to the
outside environment.
See Appendix A, “Technical Specifications” on page 121 for a description
of the alarm input and alarm output pinouts.
Alarm Input
You can connect an alarm input to a dry contact switch, such as a door
switch. There are no polarity requirements if the port is connected to a
non-powered mechanical switch. There is an internal isolated power
supply that provides a maximum of 5V and 20mA through the contact.
Caution
Do not apply external power to any of the alarm input’s leads.
Alarm Output
The alarm output consists of a relay contact that can handle 0.8A of
current at a maximum voltage of 48V DC. You must provide a series
resistance that will limit the current accordingly.
