SMOKE DETECTORS

Smoke detectors are available as factory-installed options on

50HC models. Smoke detectors may be specified for supply air

only, for return air without or with economizer, or in combina-

tion of supply air and return air. Return air smoke detectors are

arranged for vertical return configurations only. All compo-

nents necessary for operation are factory-provided and mount-

ed. The unit is factory-configured for immediate smoke detec-

tor shutdown operation; additional wiring or modifications to

unit terminal board may be necessary to complete the unit and

smoke detector configuration to meet project requirements.

System

The smoke detector system consists of a four-wire controller and

one or two sensors. Its primary function is to shut down the roof-

top unit in order to prevent smoke from circulating throughout

the building. It is not to be used as a life saving device.

Controller

The controller (see Fig. 49) includes a controller housing, a

printed circuit board, and a clear plastic cover. The controller

can be connected to one or two compatible duct smoke sensors.

The clear plastic cover is secured to the housing with a single

captive screw for easy access to the wiring terminals. The con-

troller has three LEDs (for Power, Trouble and Alarm) and a

manual test/reset button (on the cover face).

Smoke Detector Sensor

The smoke detector sensor (see Fig. 50) includes a plastic

housing, a printed circuit board, a clear plastic cover, a sam-

pling tube inlet and an exhaust tube. The sampling tube (when

used) and exhaust tube are attached during installation. The

sampling tube varies in length depending on the size of the

rooftop unit. The clear plastic cover permits visual inspections

without having to disassemble the sensor. The cover attaches to

the sensor housing using four captive screws and forms an air-

tight chamber around the sensing electronics. Each sensor in-

cludes a harness with an RJ45 terminal for connecting to the

controller. Each sensor has four LEDs (for Power, Trouble,

Alarm and Dirty) and a manual test/reset button (on the left-

side of the housing).

Fig. 49 — Controller Assembly

Air is introduced to the duct smoke detector sensor’s sensing

chamber through a sampling tube that extends into the HVAC

duct and is directed back into the ventilation system through a

(shorter) exhaust tube.
The difference in air pressure between the two tubes pulls the

sampled air through the sensing chamber. When a sufficient

amount of smoke is detected in the sensing chamber, the sensor

signals an alarm state and the controller automatically takes the

appropriate action to shut down fans and blowers, change over

air handling systems, notify the fire alarm control panel, etc.
The sensor uses a process called differential sensing to prevent

gradual environmental changes from triggering false alarms. A

rapid change in environmental conditions, such as smoke from

a fire, causes the sensor to signal an alarm state but dust and

debris accumulated over time does not.
The difference in air pressure between the two tubes pulls the

sampled air through the sensing chamber. When a sufficient

amount of smoke is detected in the sensing chamber, the sensor

signals an alarm state and the controller automatically takes the

appropriate action to shut down fans and blowers, change over

air handling systems, notify the fire alarm control panel, etc.
For installations using two sensors, the duct smoke detector

does not differentiate which sensor signals an alarm or trouble

condition.
