Description
The Edwards 5570M intercom is a heavy-duty UL and cUL
Listed signal appliance designed for use in industrial applications. Models are available in 120/240V AC 50/60 Hz
and 24V AC/DC. 120 or 240V AC operation can be
configured by means of a slide switch. The AC line has a
1/2 amp 250 volt type GMC fuse. Operating selections
include balanced or unbalanced line operation and modes
of Master or Satellite can be selected. The unit features a
transformer isolated audio input and a choice of one of four
selectable alert tones. For indoor applications where ambient noise is high, a Cat. No. 5570MIC hand-held noise
cancelling microphone kit is available.

5570M INDUSTRIAL INTERCOM
User Guide
Master Mode
Alert Button
When configured as a Master unit, the intercom constantly
broadcasts any signal received on the signal lines over its
speaker. Depressing the Listen/Talk switch changes the
unit from a speaker to a microphone (Figure 2) allowing the
user to transmit over the signal lines to additional intercom(s)
connected to the audio line. Releasing the Listen/Talk
switch returns the unit to the Listen mode, allowing the
user to receive messages. The intercom is supplied from
the factory set in Master Mode (figure 3, switch S3-1 is in
the "ON" position). Up to 938 units can be connected in
Master Mode.
CAUTION
To avoid hearing damage, do not depress the alert
button while carrying on a conversation over the
intercom system.
Depressing the alert button will send a user-selected tone
across the signal lines. All units listening to this line will
broadcast this as a signal tone.
NOTE:
Satellite Mode
NOTE:
Only one master and one satellite can be
interconnected for use in Satellite Mode.
Satellite mode is designed for applications that require the
intercom to constantly transmit instead of receive. In this
mode, depressing the Listen/Talk switch allows the user to
Listen to audio being transmitted through the interconnected Master intercom.
If the volume on the receiving unit(s) is turned
all the way down, the alert signal will not be
heard. To avoid this problem, connect an
external signaling device to the dry contacts.
Dry Contacts to External Device
Depressing the alert button will close a normally-open dry
contact which can be used to activate an external visual or
audible signal appliance. The dry contact is to be connected to a power limited source only. The contact is rated
at 2.0A at 24V AC/DC, P.F. = 1.
Refer to Figure 5 for
wiring instructions and the table below for relay delay.
Isolated Balanced/Unbalanced Lines
SW3
Audio signals for the 5570M are transmitted over a wire
pair using balanced line technology. An isolation transformer, located at the input of the intercom, has a center
tap connected to ground allowing two legs of AC that are
180 degrees out of phase with respect to one another, so
that ground currents are cancelled out . This isolation
eliminates problems caused by non-isolated systems. Polarity of the audio lines does not need to be observed.
In cases of extreme interference, shielded cable should be
used with the shield or drain wire connected to the ground
of only one intercom.

*Relay Delay is the amount of time the

Optional Microphone
Surge Protection
Place the intercom in transmit by keying the microphone
(push-to-talk).
Transient Voltage Suppressor devices are used to protect
the audio lines, remote control line and 24(+) DC OUT and
24 (-) DC OUT power lines. The intercom must have Earth
Ground terminated to it to ensure surge protection.
Installation
The output amplifier of the 5570M offers full short circuit
protection and overheat protection.

WARNING
Do not apply power to the unit until installation is
completed and housing cover and outlet box cover
are secured.
1.
Remove the cover from the front of the intercom.
2.
For 5570M-NR5 models being installed with 240V AC
power, set SW1 to 240V AC (Figure 3).

3.
The intercom is factory set for balanced line operation.
For unbalanced line operation, place a jumper on JP12 and JP1-3 as shown in Figure 3.
10. Attach earth ground to the green and yellow striped
lead (Figure 3). Select the appropriate wiring method
from Figures 5 - 10 and wire accordingly.
4.
Configure the intercom for Master or Satellite Mode
operation using switch S3-1 (Figure 3). Factory default
is Master Mode.
11. To switch the intercom into Satellite Mode, where
desired, ensure power is off and perform the following:
5.
Select a tone from Table 1 and set SW3-2 and SW33 as indicated (Figure 3).
a.
Loosen the rubber boot covering the Talk/Listen
toggle switch and rotate the toggle switch 180
degrees. Ensure the locking ring is seated in the
locating hole on the back of the cover plate
(Figure 2). Retighten the rubber boot against the
cover plate with the toggle switch in the talk
position (Figure 2).
b.
Change the MAS/SAT dipswitch S3-1 to the "OFF"
position for Satellite Mode (Figure 3).
c.
When the unit is placed in Satellite Mode it defaults
to the Talk or transmit mode. When hooked to a
Master unit , the master acts like a speaker and
broadcasts audio signals from the Satellite. As an
option, the Master can override the Satellite unit by
connecting a wire between the J3-5 and J3-6
screw terminals, 24(-) DC OUT and remote control
respectively (Figure 10), between the Master and
the Satellite units on both terminal blocks. In this
mode, pushing the listen/talk switch on either unit
forces the satellite into the listen mode and the
Master into the talk mode.

6.
If using optional 5570MIC mount the mounting plate
within reach of microphone cord (Figure 11). For
weatherproof applications see instructions for 5542WPK.
7.
If external microphone, Cat. No. 5570MIC, is installed,
set switch S3-6 to the "ON" position (figure 3).
8.
Mount the unit using the two ears on the exterior of
the housing (Figure 1) using hardware (not supplied)
appropriate for the selected surface. Concrete wall
mounting is preferred with appropriate wall anchors and
hardware that will support a minimum of 15 lbs (wall
anchors and hardware not supplied).
9.
Install conduit to the 1/2" - 14 IPS openings in the
bottom of the unit . Seal the threads with pipe
compound or other thread sealing material.
12. For 24V DC units, fuse the positive (+) supply conductor
at the source with a 0.5A fuse or use a power-limited
source or isolation transformer.
13. Replace cover on the Intercom.

The dry contacts can be used to switch devices such as an auxiliary light when alert
button is depressed. The contact is rated at 2 amps @ 24V AC/DC, P.F. = 1. DC applications
require a power limited source. AC applications should utilize a class II inherently power limited
source. This method assures a call is received and recognized when the volume on one of the
intercoms is turned all the way down.

This configuration is used when hooking to other products on the market. This system
does not offer the same level of noise isolation as a balanced line system and should
only be used when hooking to existing devices. The JP1 jumper on the circuit board
must be changed to the UNBAL position for these installation (see Figure 3).

In this installation, the Master is constantly broadcasting signal from the Satellite. Pushing
the listen/talk switch on either unit forces the Satellite into the listen mode and the Master
into the talk mode. The MAS/SAT switch S3-1 on the satellite unit must be placed in the
SAT 'OFF' position for this operation.
