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.

CAUTION
The LCM-OAVS has two terminal
blocks with terminations numbered
identically (terminations 1 through
16). DO NOT get these mixed up
with each other.
If the LCM-OAVS is not connected
as shown, it is not resistant to
electrical surges. It is also
susceptible to interference from
other equipment.
Le LCM-OAVS est muni de deux
bornes dont les contacts sont
numérotés à l’identique (contacts 1
à 16). NE PAS les confondre.
SI le LCM-OAVS n’est pas connecté
comme indiqué, il n’est pas protégé
contre les surtensions électriques. Il
est également susceptible à des
interférences émises par d’autres
périphériques.
CAUTION
A separate power supply is required
if a 4-20 mA sensor is used.
Failure to follow wiring precautions
will result in equipment damage.
Une alimentation séparée est
nécessaire, si un capteur 4…20 mA
est utilisé.
Risque de dégâts matériels, si les
précautions de câblage ne sont pas
respectées.
