Sensors
A variety of sensors may be used with the EA800 console to provide environmental status and information. These
include the following:
■ Wired Sensors: Outputs 1 through 4 are for use with sensors wired to the console. Wired sensors can be any
of the following types:
• Low temperature - blue thermistor probe
• High temperature - red thermistor probe
• Ultra low temperature - white thermistor probe
• HA-III+ humidity sensor
• WaterBug ® sensor (supervised only)
• Normally Open (N.O.) dry contact
• Normally Closed (N.C.) dry contact
• 4-20 mA
■ Wireless Sensors: Outputs 5 through 8 are for use with wireless sensors. These sensors transmit to the EA800
console through RF links. Each wireless sensor is hard-coded with an address the console 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 - blue thermistor probe
• High temperature - red thermistor probes
• Ultra Low temperature - white thermistor probes
• WaterBug
®
sensor (supervised only)
• Normally Open (N.O.) dry contact
• Normally Closed (N.C.) dry contact
• Wireless Supervision: EA800 wireless sensors are fully supervised for both communication drop-out
and low-battery condition. The AUX relay can be configured to give a low-battery indication (see
“Configuring the Relays” on page 34). The wireless sensor's assigned relay will change state if
communication drops out for more than 20 minutes.
Temperature Sensors
Table 5 lists the temperature sensors available for use with the EA800 Alarm System.
