70 Installation and configuration
Connecting the external alarm cable at the local site
The Fiber Remote Multi-IPE Interface unit provides an external alarm
output connector (ALM), which is connected to external alarm indicators at
the local site. These alarm outputs indicate external alarm contact closures
at the Remote IPE site and the failure of the fiber-optic link.
Use a cable with a DB-9 male connector at one end and open wires at
the other end. The open-wire end can be customized with connector(s)
to match your external alarm indicator devices. The length of the cable
depends on the distance between the Fiber Remote Multi-IPE Interface
unit and the external alarm devices.
