1. Product Description
This document describes the hardware installation procedures for the Allure
EC-Sensor-T (temperature only); a space temperature sensor, inside an Allure
enclosure (Figure 1-1), used to monitor room temperature.
The Allure EC-Sensor-T’s modern, alluring profile enclosure is suitable for
classrooms, hotels, executive areas, office spaces and other commercial
areas. It consists only of a temperature sensor (thermistor), approximately
4.75 inches (12 cm) of wire and a clip with adhesive inside the enclosure
(Figure 1-2).
Mounting hardware with a separate sub-base is provided with the device for
installation on a dry wall or on an electrical junction box.
