Ground Fault Detection Module
The GFD module is designed to detect
ground fault conditions on either of two
independent power or data circuits. Each
circuit must be balanced with respect to
ground. The module will detect when the
resistance between any of the monitored
conductors and earth ground drops be-
low 10 K Ohms. Two LEDs are provided to
indicate the conductor with the ground
condition. A normally energized Trouble/
Ground Fault relay is provided with
NO/NC relay contacts for interfacing
with monitoring systems.

Alphanumeric Pager Interface
The API-8/232ME is an interface between
alarm and monitoring equipment and per-
sonal pager systems or PCS messaging
services. The interface ensures that key
personnel, regardless of their location, are
notified of EST3 status changes. The unit
can monitor an ASCII text string from a
serial printer port for eight different event
types. Each event type is defined by one
or two programmable keywords up to 20
characters in length.

Communications Bridge
The 3-SM8051-0139 Communication Bridge converts the EST3 External Communications
Protocol (ECP) to a variety of commercial protocols that facilitate one-way and two-way
communications between EST3 and other in-building systems and sensors using a common
protocol via an Ethernet LAN.
