GENERAL INFORMATION
The Winland HA-4 is a sensor used for monitoring remote locations for rising
or falling rates of humidity.
The HA-4 is designed and approved to be used with EnviroAlert® and EnviroAlert
Professional® families of monitoring devices including the EA200-12/ 24,
EA400-12/24, EA800-I P, and the EAPro-GTWY
THEORY OF OPERATION
The HA-4 senses the ambient room humidity electronically using a capacitive sensing element. Humidity should be expected to vary from room to room and from one area of a room to another. Ventilation and airflow will greatly affect relative humidity.
When programming the HA-4 sensor on the monitor’ing device, the initial reading you receive shou Id be considered a base reading. Allow at least 30 minutes of operation for the sensor to stabilize prior to setting the high and low limits. It is necessary for the temperature of the sensor to stablilize before the readings are considered accurate. The outputs of Wi nland’s electronic monitoring devices react within seconds of a limit being exceeded. A sudden burst of humid air from a door opening or a ventilation system starting, could cause a brief change in the humidity reading. To avoid false alarms, a time delay should be programmed in to the EA200-12/24, EA400-12/24, EA800-IP, and the EAPro-GTWY. It is strongly recommended to utilize a time delay unless your application requires instant notification.
Installation
The HA-4 sensor should be flush mounted directly to a flat surface like a wall. The sensor should be located in an area free from drafts, heat sources, and direct sunlight. It is recommended that the sensor is mounted at a height of 4-5′(1.2-l.Sm) from the floor.
Wire the HA-4 to your EA200-12/24, EA400-12/24, EA800-IP or EAPro-GTWY monitoring device using the following wiring scheme (See Figures 2 and 3). Extend t he length of the probe wiring up to 1,000′(304.Sm) using 18-22 AWG twisted pair.
