ACI/RW-024 Smoke Detectors

Smoke Detectors

ACI/RW-024 Series

Product Description:

The ACI/RW024 Series duct smoke detectors provide early detection of smoke and products of combustion present in air moving through an HVAC duct. These devices are designed for the prevention of smoke recirculation in areas by the air handling systems. Fans, blowers, and complete systems may be shut down in the event of smoke detection. The 24 volt models will operate on either 24 VAC or VDC.

The ACI/RW024 may utilize either a photoelectric or ionization detector head. Each of the devices contains (2) form "C" Alarm Contacts and (1) form "C" Trouble Contact.

Visual indicators, pilot and alarm, are mounted on the housing front for status indication. A manual test/reset switch is also provided on the front of the detector.

Air sampling is accomplished by two tubes which protrude into the duct. An exhaust tube of one standard length (7.5") is provided with the detector housing. Intake sampling tubes, which must be ordered separately, are supplied in three standard lengths.
