FCC RULES AND REGULATIONS – PART 15 — This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at his own expense.
The TrueAlert family of notification appliances provides addressable control and supervision of
individual appliances and circuit wiring. Appliances are operated over a single two-wire notification
appliance circuit (TrueAlert Channel) that allows T-tapping (Class B only). The TrueAlert Isolator
+ Module provides a means of containing the effects of a short circuit on the TrueAlert Channel to a
single segment of wire, as well as an aid in locating stray connections to earth ground. The
TrueAlert Channel can be broken into segments called Virtual NACs (VNACs) in both Class B
and Class A circuit topologies using the TrueAlert Isolator + module to abut segments. TrueAlert
Isolator + Modules operate contact switches through commands received over the 2-wire
TrueAlert circuit from the 4009 TrueAlert Addressable Controller and TrueAlert Power Supply
(TPS). TrueAlert Isolator + modules automatically isolate the short to a single segment of wire,
but require a command from the host panel to restore the connection. Manual control of opening
and closing the contacts is also available through the TrueAlert Power Supply.
The range of possible temperatures under which the TrueAlert Isolator + can function is between
0C (32F) and 49C (120F).
The TrueAlert Isolator + operates normally under non-condensing humidity conditions up to 93%
with relative humidity at 38C (100F).
The TrueAlert Isolator + Module has a LED that the TrueAlert Addressable Controller can
command to Flash ON, OFF, or blink when polled. See Figure 1, TrueAlert Isolator + Module.
Note: The TrueAlert Isolator + Module is a faster version of the original TrueAlert Isolator. It is a
100% backwards compatible replacement for the original version. You will not necessarily gain
the enhanced speed benefit of the short isolation unless all your isolators are the new "+" type on
the same TrueAlert Channel. The "+" version can be identified by looking at the silkscreen on the
PCA for "TrueAlert Isolator +" located near the terminal block.
