ZPS-H (Zone Presence Sensor for Fume Hood Applications)

Note: Please read this entire document to familiarize yourself with the installation and wiring

instructions for the ZPS-H Hood Presence Sensor. For additional details, refer to the individual product

Submittal Drawings, User Manuals and Job-Specific Requirements.

OVERVIEW

The ZPS-H Zone Presence Sensor is an optional sensor used with the AVC Fume Hood Control System, which will

cause the Fume Hood Monitor to revert to the Setback mode when no one is standing in front of the hood thus reducing

the exhaust requirements. Upon the return of the occupant to the front of the hood, the ZPS-H will immediately signal

the AVC Fume Hood Control System to return to the normal working velocity set point.

Caution: Wear eye protection, cut resistant gloves and clothing suitable for working with sheet metal.

Failure to do so may result in personal injury.

Select a flat surface on the front of the fume hood above the operator. Verify there is enough clearance behind the

panel to accommodate the two mounting screws and the cable. If the location is suitable, adhere the mounting template

to the surface.

Using the mounting template as a guide, drill two holes for the mounting screws and one hole for the cable.

Caution: Be sure to deburr the cable hole prior to inserting cable through the hole to prevent cable

damage.

Insert the provided cable through the hole from the front of the hood so that the terminal block is on the front of the

panel. Insert mounting screws provided with kit partially, leaving space under the screw heads to slip the sensors slotted

holes under.

Page 3 To quickly adjust pattern, press and release the Reset Button and then press and hold the Install Button for 3 seconds (the LED will flash orange to confirm). This puts the ZPS-H into an install mode that is constantly sensing, but not driving the signal to the AVC.
Page 4 2f. Verification Once the ZPS-H is set up, verify that the Digital Input of the AVC is configured to trigger the setback to lower flow and test entire system by walking in front of the hood to verify that the hood responds appropriately. Repeat walking test to verify proper operation.
