Choosing the Best Location for the EK1000
Mount the controller in a secure but accessible location. System administrators
will program the system at the EK1000, so proper mounting of the EK1000 door
controller will allow the display to be easily viewed by the system administrators.
Installing the Power Supply
The Easikey 1000 requires one of the three types of power sources shown
below:
A 12 VDC 3 Amp power supply.
A 24 VDC 1.5 Amp power supply.
A 16.5V AC power source at a minimum 40VA rating. Radionics offers the
D1640 transformer that supplies 16.5 VAC @ 40VA.
AC Power LED OFF in Editor Mode:
When the AC power supply is providing
power to the controller, the red LED on the controller illuminates, except when
the controller is in the Editor's Mode. If you are using a 12 VDC power source the
red LED will not illuminate even though power is supplied to the EK1000.
The EK1000 door controller and two Easikey readers require 600mA. In addition,
the power supply must provide power for locks you attach to the EK1000. Each
lock output can supply up to 1 Amp continuously at 12 VDC. Therefore, choose a
power supply capable of providing between 2.6 Amps and 3 Amps total,
depending on the current
consumption of the locks.
The database is preserved when
power is completely lost:
The
controller stores the database in
battery-backed memory. If AC and
battery power are both disconnected
from the EK1000, the EK1000
preserves the information in the
database. The database is preserved
for up to 12 months when the EK1000
is not powered. An internal NICAD
battery is charged as long as the
EK1000 is powered. If the NICAD
battery discharges during a power
failure, it recharges when power returns to the EK1000. Installers or users
cannot replace the internal NICAD battery. The NICAD battery must be replaced
at the factory.
Figure 3 shows where to connect the power source being used to the EK1000
door controller.
Choosing the Stand-by Battery and Low Battery Indicator
Before choosing the battery to the power supply, calculate the battery's capacity
requirement based on:
The current consumption of the EK1000 and Easikey readers (up to 600mA).
The current consumption of the locks when operating normally (up to 1 Amp
