5. Complete the copy of Appendix B: Planning Worksheet for the facility in which the EA800 system is to be
installed. This must include all monitored areas for the total security system so that you know how many EA800
base units are needed.
6. Determine the sensors required from the Planning Worksheet you completed and the information provided for
each sensor type in “System Configuration”. Enter these in the copy of the System Configuration Record you
made.
Note: When water sensors are required, you must use at least one supervised water sensor and may add up to
five additional unsupervised water sensors, all in parallel. Thus, an alarm on any sensor will result in an
alarm with no way to determine which sensor is the source.
7. Enter the sensor information in the copy of the EA800 Wiring Diagram you made. It is a good idea to name
each sensor on this diagram and use that name in both the EA800 Wiring Diagram and the System
Configuration Record. This helps ensure proper programming of the system after you have physically installed
the system.
8. Using the floor plan you created, identify the specific locations for each sensor and verify that their locations
meet the specifications. See Specifications for operational parameters such as cable length.
Note: For 4-20mA sensors: See 4-20mA Sensors for a discussion of determining the constraints for your
4-20mA sensor to ensure accuracy over its rated range.
9. Determine the channel to use for the wireless sensors. If more than one EA800 is being installed on-site, it is
recommended that they be configured to use different channels.
10. The wireless sensor must be located so that the wireless signal strength is adequate as outlined in Winland
Application Note AN00101. You must verify that the wireless sensors can communicate with the base unit
before you permanently mount them.
Note: Certain environments may present conditions that intermittently cause interference with wireless sensor
to base unit communications. You should understand the environment in which the EA800 is to operate
to minimize their affects on system performance.
11. Decide the loop design you will use. Figure 9 shows an alarm loop where alarm power is derived from the
alarm loop. Figure 10 shows an alarm loop where alarm power is derived from the power supply feeding the
EA800.
Note: if using a self-powered loop, ensure the power supply can provide power for all loading conditions.
WARNING !
EA800 relay outputs are intended only for use as low-voltage, low-current
alarm connections, and not for direct switching or control of AC-mains
powered loads. Additionally, local codes may further dictate or limit the types
of loads and associated wiring to be used with the low-current Form C relay
outputs used with the EA800. Connecting AC-mains type circuits to the EA800
may result in an electric shock and/or fire hazard.
CAUTION !
Do not connect a load to the AUX OUT or OUTPUT 1 through OUTPUT 8 relay
outputs that exceeds limitations stated in the Specifications section of this
manual. Loads exceeding the specified limitations may damage the EA800, or
result in improper or unreliable operation.
