System Sensor
M500X
Description
The System Sensor M500X Fault Isolator modules enable
part of the communications signaling line circuit to con-
tinue operating when a short circuit occurs. The System
Sensor M500X Isolator Module is an automatic switch that
opens when the line voltage drops below four volts. This
module is rigorously designed and tested for electromag-
netic compatibility and environmental reliability, in many
cases exceeding industry standards.
When installing Isolator Modules, the modules should be
spaced between groups of sensors or modules in a signal-
ing line circuit to protect the remainder of the signaling line
circuit. If a short occurs between any two isolators, then
both isolators immediately switch to an open circuit state
and isolate the devices between them. The remaining
units on the signaling line circuit continue to operate. No
more than 20 devices are recommended for each group.
An LED indicator flashes in the normal condition and
lights during a short circuit condition. When the short cir-
cuit is removed, the module will automatically restore the
entire signaling line circuit.
