NOTE: As a standard grounding procedure, ensure
that 3" - 5" ground wire is connected directly
on the common terminal on the secondary
side of the 24 Vac transformer.
8. Connect the tubing from the air velocity sensor
pickups to the ports on the controller. Connect
HI to HI and LO to LO.
Smoke Control Compliance
The following instructions and information apply if
used for smoke control sequence.
1. Install Smoke Control Listed products, enclosure
and transformer (see the Product Numbers and
Accessories sections for more information.
2. Input Rating:
24V 60 HZ 60VA maximum
3. Digital Output (DO) are the only I/O suitable for
smoke control application.
Digital Output (DO) Electrical Ratings:
5VA per DO/ maximum 40 VA total.
4. The room temperature sensor (RTS) is installed
in the same room as the TEC.
5. Connection from the TEC to the field panel is a
maximum 4000 feet, 24 AWG minimum.
6. Wiring Range:
Transformer: primary 14 AWG
24 Vac Input Power: 14 to 18 AWG
DO: AI: 18 to 20 AWG
DI: 18 AWG
LAN: 20 to 24 AWG
RST: 24 AWG
All circuits are power limited; FLN is RS-485, RTS is
RS-232. Digital Inputs (DI) are dry contacts.
See the following documents for more information
on configuring smoke control applications:
Smoke Control Systems Application and
Engineering Manual (125-1806)
Smoke Control System Application Guide
(125-1816)
NFPA and UL Standards Relevant to Smoke
Control System Application Guide (125-
1817)
NOTE: The 24 Vac relay module is not applicable
for smoke control application.
The installation is now complete.
Wiring Diagram
The controller’s DOs control 24 Vac loads only. The maximum rating is 5 VA for each DO. An
external interposing relay is required for any of the following:
• VA requirements higher than the maximum
• 110 or 220 Vac requirements
• DC power requirements
• Separate transformers used to power the load.
