PHOTOCELL DAYLIGHTING SENSOR
Models:
61329 Contact Power Pack Ceiling Mount Photocell Daylighting Sensor, Low Voltage
Overview
The Contact Photocell Daylighting Sensor is a low-voltage
daylighting sensor that measures changes in ambient sunlight
and controls its connected lighting loads according to the
user’s programming. The unit is able to decipher minor
changes in light levels (such as passing cloud cover, intermit-
tent shadowing, etc.) to prevent unwanted or inadvertent
light cycling. In addition, the unit provides a programmable
time-delay fade from 1 to 30 minutes for smooth light-
cycling transitions.
The Photocell Daylighting Sensor is designed for use with one Contact Power Pack. Each unit
provides on and off operation when used with an 61330, 61331, or 61332 relay power pack.
When the device is connected to an 61333, 61334, 61335, or 61336 relay pack (with fluores-
cent dimming modules), the Photocell Daylighting Sensor can dim the loads according to the
space’s needs for maximum energy conservation.
Note:
Do not exceed one Photocell Daylighting Sensor per Contact Power Pack.
Installation
The Photocell Daylighting Sensor may be mounted in a junction box or directly to the ceiling
depending on local code. The unit must have an unobstructed view of the area to be monitored.
Place the photocell near an exterior window where sunlight is most visible. Mount the photo-
cell 1/2 the window height away from the window. Example: for a space with a 9 foot exterior
window, mount the photocell 4-1/2 feet away from the window.
To install:
Step 1. Check for any obstructions located behind the desired mounting location.
Step 2. Drill 1-1/2 inch hole in the desired mounting location.
Step 3. Place Photocell Daylighting Sensor through the hole and secure with supplied
washer and locknut.
Step 4. The lens may be removed to install the Field of View Customizing Template.
Simply rotate the lens cover slightly counter-clockwise and remove.
Step 5. Trim the template for the desired effect and install on interior of the lens. (Careful
placement of the template is necessary to ensure proper function.)
Step 6. Replace lens cover and verify that the unit is securely mounted.
