ZPS-H QUICK START GUIDE Rev. L 11/4/2020
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.
STEP 1: INSTALLATION
Caution: Wear eye protection, cut resistant gloves and clothing suitable for working with sheet metal.
Failure to do so may result in personal injury.
1a. Location
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.
1b. Prepare the Area
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.
Power Cable and partially installed Screw Insert Screwdriver and Pry Upwards to Remove Cover
