Applications Requiring a Secure Enclosure
For any application requiring a secure enclosure, mount
the TC Compact inside a listed enclosure along with a
Service Box and Sidewall Kit, if needed.
Power Requirements
One of the following power sources is pulled to the
enclosure:
• 120 Vac, 60 Hz and terminated at the 115V PX
Series Service Box.
• 230 Vac, 50/60 Hz and terminated at the 230V
PX Series Service Box.
• 24 Vac, 50/60 Hz Class 1 power limited from a
third-party transformer and connected to a
terminal block.
• If powering a TX-I/O expansion panel, power
wiring is run from the transformer in the primary
panel to the expansion panel, if needed.
CAUTION:
For information on extending the TX-I/O island
bus outside the enclosure, see the TALON
Wiring Guidelines Manual (588-581).
Compact Series Smoke Control
Application Requirements
CAUTION:
The 115V or 230V PX Series Service Box is
required for UL864 and NFPA92A compliant
installations. For more information, see the
PX Series Service Box Assemblies
Installation Instructions (553-131) or the
Service Box Installation Instructions (586-
135). For non-UL864 and non-NFPA92A
applications, any 24 Vac Class 2 transformer
can be used.
For smoke control applications over Ethernet
or BACnet/IP, the field panel must be
connected to the Automation Level Network
(ALN) through an Ethernet switch that is UL
Listed for Fire Signaling. ALN and FLN
circuits are supervised.
For smoke control applications, mount the TC Compact
inside a 19-inch or 34-inch PX Series enclosure (PXA-
ENC19 or PXA-ENC34). For more information, see the
19" and 34" PX Series Enclosure Assemblies Installation
Instructions (553-130).
The modem, serial cable, and surge suppressor must be
installed inside the 19-inch or 34-inch PX Series
enclosure with a Service Box.
For modems used with smoke control applications:
• The UL864 Listed surge protector is required.
• Devices connected between the USB port and
the UL Listed surge protector must be located
within the same room.
• A USB-to-RS-232 adaptor may be needed for UL
Listed modems or UL Listed printers that are not
configured for USB communication.
• The modem may be located inside the PX Series
enclosure.
Installation
WARNING:
Turn OFF AC power at the circuit breaker
panel.
CAUTION:
UL Listings require that NEC Class I and
Class II wiring be kept separate from each
other. Use separate conduit and cable tie
bars to separate Class I Digital Output (DO)
wires from all other Class II wiring.
Securely fasten the TC Compact so that it
does not come loose when point connectors
are removed.
If you need to reinsert one of the mounting
tabs, see the TC Compact Series Owner’s
Manual (588-682) for instructions.
The TC Compact may be mounted either vertically (with
24 Vac and DOs on the right) or horizontally (with 24
Vac and DOs at the top).
