529 5310 Multi-Station Remote Alarm 120 VAC version
529 5311 Multi-Station Remote Alarm 220 VAC version
DESCRIPTION OF PRODUCT
The Multi-Station Remote Alarm is set at the factory to operate at either 120VAC or 220VAC. It is capable of
providing operating status for up to four CONCOA Autoswitch systems. The Multi-Station Remote Alarm provides
power to each Autoswitch to operate the status indicator lights and the pressure switches.
An Autoswitch product that is congured with the alarm option is equipped with two pressure switch gauges, two
sets of status indicators, and a power status indicator. A pressure switch gauge and one set of status indicators are
used to monitor and report the state of the pressure for each side of the Autoswitch.
The front panel of the Remote Alarm consists of eight (8) status indicator lights, an “Alarm Silence” button, a “Test”
button, and an audible Alarm. See Figure 1. In addition to the front panel, the right side of the Remote Alarm has
a power ON-OFF switch and an IEC type connector where the AC power cable is connected. At the bottom of the
Alarm are three (3) connectors where the Autoswitch, Serial Port and Output Devices are connected.
The Multi-Station Remote Alarm controls ve (5) sets of relay contacts that are brought to the Output Connector
so they may be used to control an external device.
The status indicator lights are organized into pairs representing the Left Bank and Right Bank of an Autoswitch
System. When all congured systems are operating normally the status indicator lights will be green. If the pressure
should drop below the preset value of the Autoswitch, the audible alarm will sound and the light corresponding to
the specic Autoswitch Bank will turn from green to red. When this happens, two output relays will activate; the
MAIN relay and the AUX relay connected to the system that had the alarm condition. The MAIN Relay will
always activate whenever any of the AUX relays activates. It is sometimes desirable to silence the audible alarm
prior to the alarm condition being xed. Pressing the “Alarm Silence” button will accomplish this. The status
indicator lights and the relays will remain activated until the alarm condition is corrected. If the second bank
on the same Autoswitch generates an alarm while the rst Bank is still in an alarm condition, the other status
indicator light in that system will turn from green to red, however, both red status indicator lights on that system
will start to blink ON and OFF. If the audible alarm was previously silenced, it will sound again.

Connections to the Alarm are made through input and output connectors. Customer supplied cables are easily
soldered to the connectors prior to plugging the connectors into the Alarm. For connector pin assignments please
refer to the “CONNECTING THE ALARM” section of this manual.
Correcting the low pressure condition will return the status lights back to green, and de-activate the relays.
The Multi-Station Remote Alarm can detect if the connection to the Autoswitch is broken. If the cable is
disconnected or a line is severed, the alarm will sound. This feature is only available when using normally closed
pressure switches.
Another feature in the Multi-Station Remote Alarm is Self Test. Pressing the “Test” button on the front of the unit
will allow all status lights and outputs on the Remote Alarm to be cycled.
The Serial Port on the Multi-Station Remote Alarm also reports the alarm status. Each time there is a change to
the status of the Remote Alarm, it will send this information to the Serial Port. Refer to the Serial Port section for
details.
INTENDED USE OF PRODUCT
The Multi-Station Remote Alarm is used to monitor and report the status of inlet pressure on AutoSwitch Systems.
The Alarm can be congured to monitor up to four (4) AutoSwitch Systems. The Alarm contains one (1) common
and four (4) independent sets of relay contacts as outputs that can be used to control any device that can be activated
using a normally open or normally closed switch. One example of such a device would be the CONCOA telephone
dialer (PN 5295306).
Connections to the Alarm are made through input and output connectors. Customer supplied cables are easily
soldered to the connectors prior to plugging the connectors into the Alarm. For connector pin assignments please
refer to the “CONNECTING THE ALARM” section of this manual.

MOUNTING THE REMOTE ALARM
The Multi-Station Remote Alarm is mounted using the mounting tabs on the sides of the enclosure. It should be
placed on a secure wall or panel where it will not be subjected to shock or vibration or direct contact with liquids.
If mounted outside, it should be protected from the elements. Refer to Figure 10 for mounting detail.
CONNECTING POWER
The Multi-Station Remote Alarm is available as a 120VAC or 220VAC unit. A label is applied across the power
input connector listing the voltage the product is congured for. The 120VAC unit is supplied with a detachable
power cord. Due to the various plug congurations available, the 220 VAC unit does not come with a power cord.
A power cord may be purchased from a local electrical distributor that matches the plug requirements for your area.
The side of the power plug that mates to the Remote Alarm must have an IEC plug on it.
Remove the label covering the Power Input connector and plug the mating end of the power cord into the Remote
Alarm. Plug the other end of the power cord into a 120VAC outlet.
CONNECTING THE AUTOSWITCH
To connect the Multi-Station Remote Alarm to an Autoswitch system, an interface cable must be made. The
Autoswitch systems are shipped with a connector that is used for this cable. An Input Connector kit is also supplied
with the Multi-Station Remote Alarm.
To perform the assembly task you will need a soldering station or pencil, rosin core solder, and a wire stripper. It
would also be helpful to have a vise to hold a connector while soldering the wires to it.
OPTION 1: For Autoswitch Systems that have a 6 pin circular connector.
It will be necessary to obtain a 6 conductor cable. The length of the cable is determined by the application but
should be limited to no longer than 1500 feet. It is recommended that 22 AWG stranded wire be used. (Alpha
# 5006C or Belden #8446 are acceptable types).
Cut the 6 conductor cable to length. Remove the outer jacket of the cable to expose approximately 1-1/2 inches
of the internal conductors. Strip away inch of the insulation on each of the 6 conductors. Tin the leads of
the conductors. Slide the protective cover, cable retainer, and locking nut for the circular connector over one
end of the cable as shown in Figure 2.

Using the pin assignments shown in Table 1 and the connector views in Figure 3 and Figure 4, solder the wires
to the appropriate pins. After soldering is complete attach the cable cover, cable retainer, and locking nut to the
circular connector plug. Also, attach the connector cover to the Input connector. Finally, insert the small screws
that came with the Input Connector kit into the holes on the ears of the Input Connector so that the heads of
the screws face the wire side of the connector. Slide the retainer clips on to the ears of the Input Connector to
capture the screws. See Figure 5.
Plug the Input Connector side of the cable into the Remote Alarm and secure it by tightening the small screws.
Plug the circular connector into the Autoswitch securing it by turning the locking nut until it locks.
Figure 5
OPTION 2: For Autoswitch Systems that have a 4 pin circular connector.
If the Multi-Station Remote Alarm is being used to replace the previous multi-station Alarm (PN 5295298,
5295300) use the instructions that follow.
The existing Autoswitch system (522, 523, 536, and 537 prior to May 2002) came equipped with a 4 pin
circular connector. If it is already connected to an alarm, the 4 conductor cable already exists. Remove the
cable from the old alarm by unscrewing the wires from the terminal block. Cut the end of the cable so that
the wires that went into the terminals on the terminal block are removed. Remove the outer jacket of the
cable to expose approximately 1-1/2 inches of the internal conductors. Strip away inch of the insulation
on each of the 4 conductors. Tin the leads of the conductors.
Using the pin assignments shown in Table 2 , and the connector views in Figure 6 and Figure 7, solder the
wires to the appropriate pins of the Input Connector. You will need to remove the protective cover, cable
retainer, and locking nut to the circular connector plug to see the pin outs. After soldering is complete re-
assemble the 4 pin plug assembly and attach the connector cover to the Input Connector. Finally, insert the
small screws that came with the Input Connector kit into the holes on the ears of the Input Connector so
that the heads of the screws face the wire side of the connector. Slide the retainer clips on to the ears of the
Input Connector to capture the screws.
Plug the Input Connector side of the cable into the Remote Alarm and secure it by tightening the small
screws. Plug the circular connector into the Autoswitch securing it by turning the locking nut until it locks.
You will need to change DIP switch 5 when using this Option.

CONNECTING THE OUTPUTS
The Multi-Station Remote Alarm activates relay contacts in response to alarm conditions. These relay contacts
can be connected to any external device that is activated by the opening or closing of a switch. Examples would
be CONCOA’s telephone dialer, a Warning Light, an external buzzer, or another monitoring or alarm system.
Whatever the connecting device, care must be taken not exceed the rating of the relay contacts (Table 3). Refer
to Table 4 for the pin assignments for the Output Connector.

USING THE SERIAL PORT
The Multi-Station Remote Alarm is equipped with an RS-232 Serial Port. The Serial Port can be connected to
a standard PC to expand the communication features of the Alarm.
Communication between the Alarm and the PC is Asynchronous, Full Duplex. System Bank Pressure Status
along with test information can be sent to the PC. In addition, this port is used to receive commands from the
PC.
Baud Rate is 9600. No Parity bit is used.
Each time the status of a System changes the Alarm will make this information available to the Serial Port
as an 8 bit word. The data is organized such that each bit represents the status of a BANK Pressure Switch.
Table 5 shows the bit assignments.. A value of “0” in a bit indicates IN-ACTIVE or NO ALARM condition.
A “1” in a bit indicates an ACTIVE or ALARM condition.

Communication between the PC and the Remote Alarm will use the RTS and CTS lines to control the ow of
data.
The Serial Port has the capability of transmitting the following data to the PC:
Table 5
Command Code Keystroke Denition
STX Hex 02 Cntrl-B Start of Text
Data Byte Alarm Status
ETX Hex 03 Cntrl-C End of Text
ENQ Hex 05 Cntrl-E Enquire
Table 6
The Data byte is 8 bits in length (start, stop, parity not considered). When the Remote Alarm detects a change
in status from any of the SYSTEM BANK switches, it will send out three bytes to the PC. Each byte is sent
using the handshaking created by linking the RTS and CTS lines between the two devices. The bytes are STX,
data byte, and ETX.
The Serial Port has the capability of receiving data from the PC. The data that it is capable of interpreting is
limited to the following:
Command Code Keystroke Denition
CAN Hex 18 Cntrl-X Cancel
ENQ Hex 05 Cntrl-E Enquire
STX Hex 02 Cntrl-B Start of Text
ETX Hex 03 Cntrl-C End of Text

Table 7
CAN Command – The Remote Alarm should interpret this as a Reset. Upon receiving this command, the software
should jump to the beginning or initialization.
ENQ Command – When this is received the Remote Alarm should provide the status of the SYSTEM BANK Switches.
This command coming from the PC has no "STX" or "FTX" associated with it. This is done by transmitting the
STX command rst, followed by the data byte, followed by the ETX command. This command can also be sent to
the PC if the PIC does not understand the instruction it received.
DC4 Command – When this is received the Remote Alarm will initiate the self test sequence.
Connection to the Serial Port is made through a 9 pin D-subminiature connector. The cable needed is a standard
serial cable normally used to connect any peripheral serial device to a PC. The pin assignments for the 9 pin D-
subminiature connector on the Alarm are shown in Table 8 and Figure 9.

CONFIGURING THE REMOTE ALARM
The Multi-Station Remote Alarm can be congured to select various options. These options include:
a. Enabling the Alarm to monitor 1, 2, 3 or 4 systems
b. Disabling the Audible Alarm
c. Selecting whether it recognizes Normally Open or Normally closed pressure switches
Enabling the Alarm to monitor 1, 2, 3 or 4 systems
The Multi-Station Remote Alarm is factory set to recognize one (1) Autoswitch system. As a result, only the
status lights that pertain to SYSTEM 1 will light when the unit is powered up. If more than one system is to be
connected to the Alarm a series of D.I.P. switches need to be set inside the unit. To do this:
1. Make sure AC power is off and unplug the Power cord from the Remote Alarm.
2. It is best to set the unit on a at surface. With the Alarm placed so that the Input/Output connectors
are facing towards you, unscrew the four (4) screws that hold the cover on. They are retained in the
cover so there is no need to remove them completely.
3. Carefully lift the cover. There are two cables that connect the cover to the base of the unit. Without
unplugging these cables, carefully set the cover back enough to gain access to the DIP switches located
inside in the upper left hand corner.
4. Locate the DIP switches and then using a stylus or small screwdriver, close the DIP switch for the system
you wish to enable. Refer to Table 9 and Figure 10 to select the correct DIP switch.
5. Place the cover back on the base. Be careful not to pinch the cables coming from the cover. Tighten
screws.
6. Reconnect the power cord and plug unit in.
