Description

The A+CLASS™ Daylight Sensor provides daylight level information to the Classroom Control Module. The Daylight Sensor continuously

measures daylight levels and sends this information to the Classroom Control Module.

speciFicAtions

• Supply voltage (supplied by Classroom Control Module): 24VDC

• UL and cUL listed when installed as part of a complete A+Class™ System

• 5-year warranty when installed as part of a complete A+Class™ System

precAUtions

• CAUTION: FOR USE WITH CLASS 2, LOW VOLTAGE SYSTEMS ONLY. DO NOT USE IN HIGH VOLTAGE APPLICATIONS.

• Read and understand all instructions before beginning installation.

• NOTICE: For installation by a licensed electrician in accordance with National and/or local Electrical Codes.

• NOTICE: For indoor use only.

• CAUTION: USE COPPER CONDUCTOR ONLY.

• Conrm device ratings are suitable for application prior to installation. Use of device in applications beyond its specied ratings or in

applications other than its intended use may cause an unsafe condition and will void manufacturer’s warranty.

• NOTICE: Do not install if any damage to product is noticed.

incLUDeD coMponents

1. Classroom Control Module (CCM)

2. 50' Green low voltage cable

with CAT5 connection on one end and snap-in connection which mates to Daylight Sensor on the other end (See Figures 1 and 1a).

3. Daylight Sensor with pre-installed low voltage Quick–To-Install™ (QTI) connector. The sensor’s QTI connector quickly mates to the

snap-in QTI connection on Green low voltage cable, also provided (See Figure 2).

4. A+CLASS™ Lighting xtures with 0-10V dimming ballasts installed for the General lighting mode.

DAYLiGHt sensor pLAceMent

The Daylight Sensor must be placed to see only daylight with no contribution from articial light sources. The sensor typically mounts on the

ceiling between the window and the row of xtures closest to the window. For skylight applications, the sensor mounts in the lightwell. The

sensor is aimed toward the daylight. A light meter is required for light level measurements at the task areas (See Figure 3).

A+CLASS™ Daylight Sensor Technical Installation Data INSTALLATION Instructions 1. The sensor’s foot candle range is set via a jumper switch. Default setting: 30 – 3000 FC (Typical for most applications). If the sensor’s range needs to be changed, pry cover off using a screwdriver and set jumper switch accordingly. It is recommended that prior to changing the default setting, first set up the A+CLASS program for Daylighting in the Classroom Control Module (CCM) and verify that a different range is needed.
PAGE 3
A+CLASS™ Daylight Sensor Technical Installation Data Changing Daylight Sensor Settings Perform these changes only if necessary to ensure proper daylight sensor interaction with the CCM (Classroom Control Module). IN MOST CASES THE STANDARD FACTORY SETTING OF 3-300 FC WILL BE OPTIMAL. It is not recommended changes to the setting be made unless footcandle readings shown in the DAYLIGHT menu of the CCM dictate that this change is necessary. See CCM Operating Manual for further details. 1.
