IS820 Analog Addressable 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 prevention of smoke re-circulation in areas by the air handling system (s). Fans, blowers, and complete systems may be shut down directly by the two 10A form “C” alarm relays provided in the duct smoke unit when smoke is detected.
The duct detector requires an external 24VDC supply, so as not to load down the analog addressable loop (SLC). Visual indicators, pilot and alarm, are mounted on the housing front for status indication. A manual test alarm relay switch is also provided on the front of the detector. Remote accessories can be accommodated.
The IS820 utilizes a Harrington Signal, Inc photoelectric (-P) or ionization (-N) analog addressable detector head which is included with the unit.These devices have unique features that benefit the installer and the end user; it’s user friendly addressing, extended data and alarm feature meet the demands of today's high-technology environments, codes and standards, as well as providing additional life safety functionality.
Each Harrington Signal, Inc duct detector is supplied with an X-pert card. In order to set the proper address, consult the addressing guide. Place a screwdriver in the pip's slit and five it a firm twist. Removal of the proper pip(s) completes the addressing procedure. Slide the coded xpert card into the side of the base, making sure it locks in position. Once the detector head is placed into the base, the remaining pips will operate the address buttons on the detector head and the address will be read by the head's electronics.
 Factory pre-programmed X-Pert cards which have the appropriate address pips removed, and the address number silk screened on the protruding tab can be purchased if desired.
Air sampling is accomplished by two tubes which protrude in the duct. An exhaust tube of one standard length (7”) is provided with the detector housing.Intake sampling tubes, which must be ordered sparately, are supplied in three standard lengths.
