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:

•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
