Smoke And Fire Protection - Daikin Maverick II MPS062E Installation And Maintenance Manual

Smoke and Fire Protection

Improper smoke, fire, or fume air handling can result in severe personal
injury or death.
Daikin optionally offers factory installed outdoor air, return
air, and exhaust air dampers as well as smoke detectors in
thereturn air openings, complete with wiring and control. These
components often are used in the building's smoke, fume, and
fire protection systems. However, due to the wide variation in
building design and ambient operating conditions into which
our units are applied, we do not represent or warrant that
our products will be fit and sufficient for smoke, fume, and
fire control purposes. The owner and a fully qualified building
designer are responsible for meeting all local and NFPA
building code requirements with respect to smoke, fume, and
fire control.
Factory installed smoke detectors have similar wiring and the
control sequence is as follows:
• When smoke is detected, normally closed sensor
contacts open. This removes power from binary input B18
on the main control board.
• The MicroTech III controller responds by shutting down
the unit. The controller is placed in the Alarm OFF state
and cannot be restarted until the alarm is manually
cleared. Refer to the operation manual supplied with the
unit for information on clearing alarms.
• The smoke detectors must be reset manually once they
have been tripped. Power must be cycled to the smoke
detector to reset.
