2 Installation and Startup
2.1 Connect Power Cabling
Before beginning startup, you will have to connect power to the receiver. To
connect power to the receiver:
1. Use a small screwdriver to press the housing release tab on the top or
bottom of the receiver; separate the housing.
2. Connect power cabling to the Power and GND connections.
• Power source should be 11-14 VDC. Power supply must be
unswitched, uninterrupted, and regulated.

2.2 Select the Frequency Band
EchoStream products are able to use a range of radio frequencies, and
must be configured for your geographic area. To configure the receiver:
1. Place a selection jumper on the appropriate frequency band selection
pins.
• Leave the jumper off the pins to set the frequency range to 902-928
MHz for North America.
• Place the jumper on the top two pins, marked NZ, to set the frequency
range to 921-928 MHz for New Zealand.
• Place the jumper on the bottom two pins, marked AUS, to set the
frequency range to 915-928 MHz for Australia.
Note: North American is also selected when the jumper is only attached to
one pin. This can prevent the jumper from being lost when selecting North
America.
2. Cycle power source to reset.
2.3 Program the Receiver
Note: If changing programming for a point that already has a transmitter
registered to it, there is no need to re-register the transmitter. Changes to
point programming are automatically assigned to the transmitter registered
to that point.
The default settings are:
Point Supervision
Window
1 4 hours 1 Follow N/O
2 4 hours 2 Follow N/O
3 4 hours 3 Follow N/O
4 4 hours 4 Follow N/O
F N/A Fault Inactive is set to follow; low
To program any of the four transmitter points or the fault output:
1. Use a small screwdriver to press the housing release tab on either side
of the receiver; separate the housing.
2. Use the Advance button to select any of the four transmitter points or
the fault output (Fig. 4).:

Note: The only programmable parameter on the fault output is whether the
output is normally opened or normally closed. If F is selected on an
EN4204, the EN4204 automatically advances to the switch option; an
EN4204R will not advance.
3. Press the Program button to begin programming the point. If no
transmitter has been registered to the chosen point, the receiver
advances to the supervision window option.
Note: If a transmitter has already been registered to the chosen point, the
Delete LED lights. Press Advance to delete the point and return to normal
operation; press Program to advance to the supervision window option.
4. Use the Advance button to choose a supervision window of None, 2h,
4h and 96h. Press Program to complete and advance to the output
option (Fig. 5).

four output types:
Follower: The output reflects the transmitter’s alarm status.
Momentary: The output turns on for seven seconds, then turns off,
regardless of the device status.
Toggle: The output changes state each time the device sends a new
activation. A minimum of four seconds must elapse before the output can
send a new activation.
Latching: The output turns on when activated and remains on until the
receiver is reset.

8. All the option LEDs will light and the point you’ve just programmed will
flash. If you wish to register a transmitter to the point you’ve just
programmed, press the transmitter’s Reset button; otherwise, press
Program to save programming changes without registering a
transmitter.
Note: All of the alert LEDs will turn off when the receiver has received the
transmitter’s registration message, and the point number LED will light for
two seconds. The registration is not complete until all LEDs turn off and the
point number lights, indicating the receiver has received the transmitter’s
registration message. If this does not occur, press Reset on the transmitter
again.
2.4 Factory Config
The factory config option is used to restore the EN4204 to it factory
defaults.
Caution: The factory config will erase all programmed point, output, and
language information.
To restore the factory configuration defaults to the EN4204:
1. Hold down the Reset and Advance buttons.
2. With the buttons held down, cycle EN4204 power.
3 Connect Input/Output Cabling
1. Connect cabling to the tamper output.
• The optional tamper output is a normally open (N/O) output that
reports receiver case tamper to an external device.
2. Connect cabling to the jam output.
• The optional jam output is a normally closed (N/C) output that opens
when noise thresholds on all transmission channels remain above a
predetermined value for any 30 seconds in any 60 second window.
The jam output is is set to the follow output type.
3. Connect cabling to the reset input.
• The optional reset input circuit permits installation of a remote
momentary normally open (N/O) switch to clear faults, unlatch outputs
and reset the receiver to a normal state.
4. Connect cabling to the output terminals.
5. Close receiver housing.
