Modular 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.
NOTE:
For smoke control applications over 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 Modular 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 controller must be located at the bottom of the enclosure.
● The controller may be oriented either horizontally or vertically. See the following
figures.
For modems used with smoke control applications:
Modem Requirements
● The UL864 Listed surge protector (538-600) 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.
