Addendum to the MCS 500 Automatic Dialer Operation Manual, Rev. B
Software Release 2.11
July 8, 1993

Additional Feature PROGRAMMABLE START MODE

Some applications desire that the dialer powers up in an active calling mode. A
Start MODE field has been added to the System Setup screen which allows the
user to program the dialer to enter either a half or run state upon power up. This
selection is made by entering the System Setup screen and toggling the Start
MODE field between the HALT and RUN choices.

Operational Change LATCHED ALARM VOICE MESSAGE

The alarm voice message now reports the state of an alarm channel, instead of
the current state, until the alarm has been acknowledged. So, if an alarm
occurred on a channel programmed to Latch, and then the channel returned to
normal, the voice message will report that channel is in alarm until the alarm is
acknowledged.

Addendum to the MCS 500 Automatic Dialer Operation Manual, Rev. V.
Software Release 2.05
June 26, 1992

Additional Feature USE OF THE # AND * KEYS AS TELEPHONE NUMBERS

Some Dialer applications involve paging systems which frequently use some of
the non-digit telephone tone keys. For programming telephone numbers which
must contain the # and * keys into directory positions use the following
procedures:

1. To enter the # character into a telephone number use the magenta key
(pink).

2. To enter the * character into a telephone number use the cyan key (blue).

3. To enter a 2 second pause into the telephone numbers use the SP key
(also named RUN).

Additional Feature AUTOMATIC ACKNOWLEDGMENT OF ALARMS

Some applications desire that the dialer place telephone calls, and automatically
enter the snooze period, as if a call had been acknowledged. A field has been
added to the telephone number directory programming which allows the user to
designate a telephone number as an Automatic Acknowledged telephone
number. This selection is made by toggling the acknowledge field between the
“Required” and “Automatic” choices. When the system encounters and dials a
number designated as Automatic Acknowledge, the number will be dialed and
the call will be completed. The system will then acknowledge all existing alarms,
and enter the snooze period for the programmed duration.

Clarification PARALLEL PRINTER OPTION

The figure on page 14 of the manual illustrates the position of the DB-25 Printer
Port. Although the figure uses the work “Serial” to identify the location of the DB­25 Serial type port, the system requires the use of a parallel printer.
MICROTEL,INC recommends the use of Epson parallel printers with the use of
the MCS 500 Printer Option Card.

I. INTRODUCTION

I.A. General Information and Theory of Operation

The Microtel MCS 500 Dialer is a complete Automatic Dialing telemetry system, capable
of fulfilling virtually any type of alarm monitoring or data acquisition need. The basic
system is capable of monitoring alarm conditions on a variety of analog and digital
channels, and advising personnel of the conditions which exist at the remote monitored
site. Upon detection or determination of an alarm condition, the system will place a
series of telephone calls to as many as 64 different telephone numbers. Using its own
“default” voice messages or using user-entered “Real Voice” messages, the system will
advise the call recipient of the location and the nature of the alarm conditions which
caused the call sequence.

A variety of programmable features make the Microtel MCS 500 Dialer the most
versatile and sophisticated alarm dialer available. An extensive remote programming
capability allows the user to reprogram the system using a standard tone dialing
telephone.

The system contains separate computer and I/O buses, allowing field configuration,
upgrading, and expansion of the basic system to meet the individual needs of the user.
Whether the monitoring requirement is 8 channels or 40 channels, with digital inputs,
analog inputs, or relay outputs - the system may be field configured and upgraded
without removing it from service.

A unique voice mail feature allows the user to send messages of interest to other
personnel involved with a monitored site. Voice mail messages are either deposited in
the system for access by other callers, or may be delivered by the system to any other
telephone number.

.

II.A. System Description and Familiarization - Chassis Cards

The following section is intended to familiarize the user with the basic components of
the Microtel MCS 500 Dialer. The system is housed inside a NEMA12 fiberglass
enclosure. On the bottom side of the enclosure are five, 3/4 inch conduit-size holes for
the routing of power lines, telephone lines, the system microphone, and alarm channel
sensing conductors, and printer output connections. Inside the door of the enclosure is
the system chassis which is divided into several sections. These sections and the
circuit elements which reside therein are described below. The following figure
illustrates the major components of the MCS 500 system.

5

II.A.1 LCD Panel and Keyboard

The door of the inner chassis contains the system’s 20-key keyboard and the LCD
display panel. These circuit modules are connected to the System Bus via a 20
conductor flat cable.

II.A.2. System Bus Assembly

Located in the upper section of the chassis is the System Bus. The Bus and card cage
contains printed circuit board connectors sockets for up to five circuit cards. Two of the
plug-in circuit card connectors are specifically designed to accept the CPU card (card
slot J1) and the Telephone Interface Card (card slot J5). The other three slot positions
(J2, J3, and J4) accept other system level circuit cards such as the Speech Synthesizer
card and the Speech Memory cards. The System Bus contains all circuitry necessary to
route audio and computer signals from card to card, and out to the I/O bus located in
the lower section of the System Chassis.

II.A.3. Power Supply Card

Located to the left of the System Bus Card, and directly above the Battery well, the
Power Supply occupies the extreme left card position. The Power Supply Card does
not, however, plug directly into the System Bus Card. The Power Supply delivers power
to the entire system, and contains indicators for AC Power, +5 Volts Power, +12 Volts
Power, and Low Battery. Additionally, the Power Supply Board contains a three
position terminal strip for incoming AC power, a 1/2 Amp fuse, and the system power
switch.

II.A.4. System Battery

The system battery is located to the left of the I/O bus card cage. The battery is a 12
volt, 7.0 ampere-hour battery, capable of powering the system through extended power
outages. The total battery backup time is dependent upon several factors, but it is
primarily related to the types of option cards installed in the system and the age of the
battery. The following matrix illustrates the typical battery lift for various combinations of
Digital and Analog Input Cards.

6

II.A.5. CPU Card

The CPU card must occupy J1, the left most circuit card connector on the System Bus.
The CPU Card contains the system’s primary microprocessor, program and data
memory, and interface circuitry for the other cards connected to the bus. The card has
a socket for a lithium battery which must be enabled to provide ongoing operation
for the Real Time Clock, also located on the CPU Card. To enable the CPU battery,
refer to the System Maintenance section of this manual.

II.A.6. Telephone Interface Card

The Telephone Interface Card must occupy J5, right-most circuit card connector on the
System Bus. The Telephone Interface card contains circuitry to connect the system to
the telephone network and to provide electrical protection to both the system and the
telephone network. The telephone line to which the system is connected plugs into the
RJ11C jack located on the Telephone Interface Card.

II.A.7. I/O Bus Assembly

The I/O Bus is located in the bottom section of the chassis, to the right of the battery
well. The I/O contains five circuit card connectors, into which the system’s I/O option
cards are to be inserted. The I/O option cards, such as the 8 channel Digital Input Card,
the four channel Analog Input Card, the four channel Digital Output Card, and the
Printer Output Card are connected to the sensors and outputs which the system is to
monitor and control during operation. The I/O Bus card connects to bus interface
circuitry located on the System Bus card, using a flat ribbon connector and cable.

The I/O Bus Card also distributes power from the Power Supply Card to the balance of
the system. The I/O Bus Card has a six-conductor cable and plug assembly which
plugs into the connector posts provided on the Power Supply Card. The System Bus
Card has a five-conductor cable and plug assembly which plugs into the connector
posts provided on the I/O Bus Card.

The I/O Bus Card also contains an Alarm-In-Process relay, which is activated whenever
the system is trying to reach someone over the telephone network. This relay may be
used to power an external alarm signaling device.

II.A.8. Adaptive Differential Pulse Code Modulation Card (ADPCM)

The ADPCM Card plugs into System Bus slot 2, 3, or 4. The Card contains all circuitry
necessary to articulate any speech programmed into the system by the user. The
system also has an internal vocabulary sufficient to provide default messages for each
channel, and to provide prompting for operation conducted over the telephone
connection. The system CPU delivers speech data from the REAL VOICE MEMORY
Card to the ADPCM card during system operation. The ADPCM Card contains a jack

7

for the optional microphone used for the intercom audio monitoring functions. The Card
also contains a small RJ style jack which accepts the carbon element telephone
handset used for entering Real Voice speech for describing all alarm and monitoring
channels.

II.A.9. Real Voice Memory Card (RV)

The RV Memory Card(s) plugs into System Bus slot 2, 3, or 4. If more than three I/O
cards are used in the system (excluding the Printer Output Card) then the system must
use two (2) RV Memory Cards. The RV Memory Card contains EPROM memories
which are programmed with the system’s “core” vocabulary - those words and phrases
necessary to articulate default messages, numerics, and prompting. Additionally, the
RV Memory Card contains eight CMOS SRAMS into which the CPU places “Real Voice”
speech data programmed by the user during programming of each channel’s
identification. The card has a socket for a lithium battery which must be enabled to
provide long-term protection for the speech data. To enable or replace the RV Memory
lithium battery, refer to the System Maintenance

II.B. System Description and Familiarization - Option Cards

Various combinations of the following circuit cards may be located in the I/O Option
Card bus on the lower half of the dialer. The cards may be installed in the field, by the
user. The user must program the dialer so that it may recognize what complement of
I/O Option Cards are installed. To select the option boards to be used, see the section
entitled, Setting the I/O Option Card Configuration

II.B.1. Digital Input Card

The Digital Input Card contains a terminal strip which will accept eight input channels.
The terminal strip provides two connectors for a common ground conductor. Each fault
sensing current “loop” is provided with 10 mA of sensing current by the system. Each
input channel is programmable for a variety of options, including integration times,
Normally-Open or Normally-Closed operation, call list, and ID Message. Time-In-Alarm
and Totalizer values are maintained by the system CPU for each input channel.

II.B.2 Analog Input Card

The Analog Input Option Card accepts four channels of 4-20 mA signals. Each channel
may have its own label, message, scaling factors, set-points, and archive
configurations.

II.B.3. Digital Output Card

The Digital Output Option Card contains four SPDT 5 amp relays. The relays may be
operated over the telephone line using telephone tone commands.

section of this manual.

.

II.B.4. Printer Output Card

The printer Output card contains circuitry which allows the dialer to print alarm logs and
other information on a standard parallel printer, employing a standard parallel interface.
The printer card must interface to the printer via a cable assembly. If the printer Output
Card is being added in the field, then the cable assembly must be routed through the
enclosure wall as described in the Printer Card Installation instructions.

III. INSTALLATION

Installation Note:

During the Installation and Programming of the MCS Automatic Dialer, it is helpful to
use the Installation Checklist, found in the appendix. Worksheets for programming
Directory Telephone Lists are also available in the appendix.

III.A. Physical System Installation

Mount the system on a wall or other vertical surface, away from and protected from
harsh extremes. It is also recommended that the unit not be placed in close proximity to
high voltage (480 V and higher) electrical equipment. Four mounting holes on the top
and bottom mounting lips are to be used for system mounting.

There are six access holes on the bottom of the unit. The two left side ports are for
power connection and the system’s telephone line connection. The right side ports are
intended to be used for the entry of input/output conductors.

The Physical Installation Diagram, found in the appendix, shows the recommended
dimensions to be used in the physical installation of the system.

III.B. Battery Installation

III.B.1. System Battery

The battery installs in the bottom left side of the system. Open the system front panel
and retrieve the red and black battery leads from beneath the battery pocket area,
located to the left of the I/O Bus assembly. Connect the battery lead terminals on to the
new battery, BEING CERTAIN that the red lead connects to the positive (+) battery
terminal, and the black lead connects to the negative (-) battery terminal.

Insert (do not force) the battery, terminals pointed upwards, completely into the battery
pocket and close the system front panel. A new battery will take no longer than 24
hours to gain a full charge, and will be capable of powering the system through power
outages many hours in length. Actual battery backup time is dependent upon the
number of channels being monitored and the number of output relays which may be
activated. It should be noted that the LOW BATTERY indicator is only valid when the
120 VAC power is on. If the LOW BATTERY indicator stays on for more than 24 hours,
the battery is in need of replacement. Contact Microtel for replacement batteries. The
Microtel part number for the System Battery is #312156.

10

III.B.2. CPU and Real Voice Memory Lithium Cells

A lithium battery is provided on the CPU card and the Real Voice Memory card. Each
of these lithium batteries must be enabled so that memory and clock functions survive
long term power outages. These batteries are enabled using the jumper plugs provided
with each card. These batteries do not recharge and should be replaced if they are
found to have less than 2.5 volts. Contact the Microtel Customer Care hot line, at (504)
276-0571 for replacement batteries. The Microtel part number for the CPU and Real
Voice lithium batteries is #312115.

III.C. Electrical Power Installation

SAFETY NOTICE!!

Be certain that the system has an adequate Earth Ground. Insufficient Earth Grounding
can prevent the internal protection circuitry from performing properly, and may cause
damage to the system.

III.C.1. Electrical Power Connection

Electrical power may be applied by connecting the three power leads (Hot, Neutral, and
Earth Ground) to a three wire 120 VAC supply. It is recommended that a separate
circuit breaker be used with the system. Remember that when the breaker is on, and
the unit is so connected, live 120 VAC is contained within the system even though the
system power switch may be turned off. Refer to the System Wiring and Mounting
diagram located in the appendix for details on wire routing procedures.

If the unit is to be installed in a location where large or high voltage motors are in use, a
separate, external power line transient suppresser is recommended (Micromax surge
suppressor). This insures that the unit is not affected by surges and spikes occurring in
the 120 VAC power. If such a device is needed, contact Microtel for assistance.

SAFETY NOTICE!!

Never ship the system with the battery installed. Remove 120 VAC Power from the
System and turn the Power Switch OFF before removing, replacing, or installing the
System Battery

III.D. Telephone Line Installation

The Microtel MCS 500 Dialer comes with a standard 3 ft. flat telephone cable for easy
connection to an RJ-11C type modular jack. The cable is connected to the Microtel
MCS 500 Dialer at the factory. The only field installation requirement is to insert the
male connector end of the cable into the user supplied RJ-11C jack. Refer to the
installation diagram located in the appendix for details on wire routing procedures.

The Microtel MCS 500 Dialer complies with part 68 of the FCC rules. On the inside of
this unit is a label that contains, among other information, the FCC registration number
and the Ringer Equivalence Number (REN). If requested, provided this information to
your Telephone Company.

The REN is useful to determine the quantity of devices you may connect to your
telephone line and still have all of those devices ring when your number is called. In
most, but not all areas, the sum of the RENs of all devices should not exceed five (5.0).
To be certain of the number of devices you may connect to your line, you should call
your local Telephone Company to determine the maximum REN for your calling area.

If the Microtel MCS 500 Dialer causes harm to the telephone network, the Telephone
Company may discontinue your service temporarily. If possible they will notify you in
advance. If advance notice is not practical, you will be notified as soon as possible.
You will be advised of your right to file a complaint with the FCC.

Your Telephone Company may make changes in its facilities, equipment, operations or
procedures that could effect the proper operation of the Microtel MCS 500 Dialer. If
they do so, you will be given advanced notice so as to give you an opportunity to
maintain uninterrupted service.

If you experience trouble with the Microtel MCS 500 Dialer, please contact Microtel at
206 West Judge Perez Drive, Chalmette, LA 70043, [phone], for repair /
warranty information. The Telephone Company may ask you to disconnect the
equipment from the network until the problem has been corrected or you are sure that
the equipment is not malfunctioning.

III.F. I/O Option Card Installation

III.F.1. Setting the I/O Option Card Configuration

The MCS 500 Dialer may be user configured to accept a variety of I/O combinations.
Using the keyboard and display, one may access a screen which allows the selection of
a different type of option card for each of the five I/O card slots in the system.
Currently, there are four types of I/O option cards:

Digital Input Card 8 Channels of digital input
Analog Input Card 4 Channels of 4-20 mA input
Relay (Digital) Output Card 4 Channels of SPDT Relay Outputs
Printer Output Card Parallel Printer Interface

. To configure the type and location

Using the PREVIOUS and NEXT keys, move the highlighted cursor to each card slot
position and use the SELECT key to toggle the entry to the physical card type which
occupies that card slot. Card slots are numbered from 1 to 5, beginning from the left
side of the lower card cage. After selecting the proper card type for any card position,
highlight and SELECT the INITIALIZE field to setup the system’s memory for that type
of card. When the inventory of I/O Option Cards is correct, move the highlighted cursor
to the EXIT field and press the SELECT key.

III.F.2. 8 Channel Digital Input Card

The 8 Channel Digital Input card is designed to accept up to eight channels of dry (un­powered), normally open or normally closed signal lines. The system provides a small
sampling current (<10mA) to determine if the contact is open or closed. Wires from
normally open or normally closed switches may be routed through the conduit port at
the lower right side of the system. Connect each wire pair to its appropriate channel
input terminal and one of the two common ground terminals provided on the digital Input
circuit card. Shielded, twisted pair, #20 or #22 gauge wire is recommended. If shielded
cable is used, ground the shield at the sensor and leave the shield floating
(disconnected) at the Dialer system. Refer to the Electrical Installation Diagram

located

in the appendix for details on wire routing procedures.

Each input channel must be configured to be either normally open or normally closed.
A channel is normally open if the “no fault” or “normal” condition is that condition which
consists of an open circuit on the channel’s wire pair. The normally open or normally
closed state of each channel may be programmed as outlined in the Section entitled,
Programming the System

.

Any unused channels should be programmed as normally open, and left unconnected to
reduce overall system current consumption. Setting the Mode of an unused Channel to
IGNORE speeds up the System operation. When the option card is installed it must be
“initialized” to inform the system of its presence. During initialization, each digital input
channel is automatically programmed by the system for various operation data values
(default values). The default for the channel’s mode is set to STATUS, meaning its
alarm condition is reported, but it will not cause calls to be originated.

III.F.3. 4 Channel Analog Input Card

The Analog Input option card will accept four, 4 to 20mA current loop signals. The
current loop signal must be externally powered. The System will monitor the current
and continuously compare the reading against high and low set-points. The results of
that comparison will determine whether or not the dialer places a telephone call
because of an alarm condition. Additionally, the High, Low, and Normal indications for
each channel may be displayed on the system LCD panel, showing the monitored
status of each channel. Two wire, shielded cable may be connected to the terminal
strip provided on the analog option card, for each channel. Shielded, twisted pair, #20
or #22 gauge wire is recommended. If shielded cable is used, ground the shield at the
sensor and leave the shield floating (disconnected) at the MCS 500 system. Refer to
the Electrical Installation Diagram

located in the appendix for details on wire routing

procedures.

During card initialization, each analog input channel is automatically programmed by the
system for various operation data values (default values). The default for the channel’s
mode is set to IGNORE, meaning it is completely disregarded by the system. This is
done to assure that the system spends no wasted time on invalid or unused channels.
