Installation
Tools and Supplies Required
Ensure that you have the following prior to starting the installation:
■ Phillips Screwdriver
■ Mounting hardware for the EA800 base unit and any optional sensor units
■ If required, a drill and the appropriate drill bits
■ Wire stripper
■ Sensors (not supplied; see “Accessories” on page 54)
■ Sensor Wiring (typically 18-22 AWG twisted-pair; not supplied)
■ Alarm Wiring (typically 18-22 AWG; see EA800 Output (Alarm) Connections)
■ Power sources
Power Requirements
All power terminals must be connected to a Class 2 power limited circuit complying with the National Electric Code
NFPA 70, Article 725. Where required, this equipment is to be isolated from the mains supply by a limited power
source as specified in EN60950.
Mounting the EA800 Rear Plate
The base unit has a removable rear plate that may be attached to a 3-gang electrical enclosure or directly to a wall.
1. Remove the rear mounting plate from the base unit as follows:
■ Pull the rear mounting plate down and away from the EA800 main chassis. The retainer tabs on the main
chassis disengage from the holes in the rear mounting plate.
■ Completely remove the mounting plate from the base unit by disengaging the mounting plate hinges from the
mating tabs on the base unit.
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 !
Connect only sensors specified in this manual to the wired and wireless input
connections. Using sensors not specified in this manual may damage the EA800 or
cause improper or unreliable operation.
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.
CAUTION !
The EA800 printed circuit board (PCB) contains electrostatic discharge (ESD)
sensitive devices. To help prevent damage caused by ESD, observe appropriate
ESD handling rules whenever the PCB in the EA800 is exposed.
CAUTION !
Batteries shall not cause explosion or produce a fire HAZARD as a result of
excessive charge or discharge, or if a battery is installed with incorrect polarity.
CAUTION !
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
