Sensors
A variety of sensors may be used with the EA800 base unit to provide environmental status and information. These
include the following:
■
Wired Sensors: Relays 1 through 4 are for use with sensors wired to the base unit. Wired sensors can be any
of the following types:
of the following types:
•
Low temperature sensors - Blue Thermistor Probes
•
High temperature sensors - Red Thermistor Probes
•
Ultra Low temperature sensors - White Thermistor Probes
•
HA-III+ humidity sensor
•
Water Bug sensor (supervised)
•
N.O. Contact
•
N.C. Contact
•
4-20 mA
■
Wireless Sensors: Relays 5 through 8 are for use with wireless sensors. These sensors transmit to the EA800
base unit through RF links. Each wireless sensor is hard-coded with an address the base unit uses to identify
the sensors installed in the system. When you program the system you assign each installed wireless sensor
to a relay using its hard coded address. Wireless sensors can be any of the following types:

•
Wireless Humidity Sensor (EA-WHS)
•
Wireless Temperature Sensor (EA-WTS)
•
Wireless Multi-Function Sensor (EA-WMFS): Any of the following wired sensors can be connected to the
wireless multi-function sensor, effectively converting the wired sensor to wireless:
•
Low temperature sensors - Blue Thermistor Probes
•
High temperature sensors - Red Thermistor Probes
•
Ultra Low temperature sensors - White Thermistor Probes
•
Water Bug sensor (supervised)
•
Normally Open (NO) Contact
•
Normally Closed (NC) Contact
