CAUTION
It is important that the neutral that
supplies the TEC must be earth
grounded at the source of the 24 Vac
power.
Possible erratic equipment operation
or damage if neutral is not grounded.
Il est très important que le neutre qui
alimente le TEC soit mis à la terre à
la source de l’alimentation 24 Vca.
Risque de fonctionnement incohérent
de l’équipement ou de dégats si le

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 60 VA maximum
3. Digital Output (DO) are the only I/O authorized
for smoke control applications.
Digital Output (DO) Electrical Ratings:
– 5 VA per DO/ maximum 40 VA total
4. The room temperature sensor (RTS) is installed
in the same area 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.
