ADSD Duct Smoke Detector
The ADSD is the duct smoke detector designed to easily mount on the side of an HVAC duct and monitor for smoke conditions
in the duct. A template and mounting hardware is provided with the unit for mounting. The device mounts without the removal of
the outer cover. The devices are designed to operate without screens and filters, therefore the amount of maintenance needed for
the device is minimal. The fire alarm panel controls the sensitivity of the smoke sensor.
Both the ADSD-P and ADSD-PR utilize a photoelectric smoke sensor. The ADSD-P has four terminals, two for the SLC loop and
two for remote output of an LED. The ADSD-PR has terminals for two form C relays that are rated for 10 amps at 125/250 VAC.
The ADSD-PR requires 24 VDC to operate. Failure to provide 24 VDC power will result in the panel showing a missing device.
The ADSD will monitor airflow between 300 and 4,000 feet per minute and require that the user purchase air-sampling tubes in
order to achieve proper airflow through the unit. Sampling tubes are available in 3, 5 and 10-foot lengths.
THE ADSD-P AND ADSD-PR ARE NOT SELF-
CONTAINED SENSORS. THIS PRODUCT IS
COMPATIBLE ONLY WITH FIRE ALARM
CONTROL PANELS THAT UTILIZE HOCHIKI’S
DIGITAL COMMUNICATIONS PROTOCOL,
DCP. FOR EXAMPLE, THE POTTER PFC-9000.

ADSD-P Wiring Diagram
The ADSD is addressed in one of two ways and both require the removal of the cover to access the smoke head. The head can be
removed and inserted on the hand held programmer and addressed like all of the other sensors. The other option is to use the FRCM-2
cable and connect to the SLC terminal strip on the ADSD. The programming of the device is the same as if it was connected.
