I. INTRODUCTION
A. GENERAL INFORMATION
The purpose of this manual is to completely explain the function, installation, and
operation of the MCS Model 250/Real Voice Communication system. This automatic
dialing, synthesized speech, telephone based monitoring system represents a new
generation of computer controlled telemetry devices, with features and capabilities not
found in any other telephone oriented monitoring system. The device is designed
specifically for industrial based equipment monitoring needs, by the engineering staff
which invented the concept of synthesized speech dialers. The Real Voice System
allows the user to actually train the system to place alarm calls. The system can then
inform the called individual of the precise location and nature of the alarm condition
using a digitized sample of the user’s voice.
The System is configured to accept four channels of normally open or normally closed
fault state switches (contacts), such as float switches, pressure switches, temperature
switches and similar devices that contain an unpowered contact that changes state
whenever a preset condition changes. Fault recognition can be set to respond after 1
second or delayed for up to 99 seconds, programmable on a channel-by-channel basis.
Internally, the system monitors its own power supply and will respond to any power
outage which persist longer than the user programmable time period.
When the dialer system recognizes an alarm condition, due to the opening or closing of
an external contact, it begins to place a series of telephone calls. The dialer system is
able to dial up to eight different telephone numbers, in an attempt to make contact with
a qualified person to whom it can deliver a combination of digitally stored voice
messages, describing the location and the type of alarm condition. These messages
are originally programmed by the user at the time of system installation.
The system will continue to call the list of up to 8 telephone numbers, insisting that its
message be heard.
The dialer system can be called at any time to check or verify the monitored conditions.
The following instructions generally describe the installation, operation and maintenance
of the equipment. Microtel reserves the right to make engineering refinements that may
not be described herein.
1
B. UNPACKING AND INCOMING INSPECTION
Microtel takes all possible precautions in packaging each item to prevent shipping
damage. Carefully inspect each package at the time of receipt for signs of physical
damage. Report damage claims to the shipping agent involved immediately. Do not
install damaged equipment.
All instructions given on any attached labels or tags should be followed. Carefully
inspect all packing material before discarding it to prevent the loss of accessories,
mounting hardware, spare parts, or instructions.
If the unit is not to be installed immediately, repack it in the shipping carton to protect it
while in storage.
2
C. PHYSICAL SYSTEM INSTALLATION
Mount the system on a wall, or other vertical surface, away from and protected from
harsh weather 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 left and right side enclosure flanges are to be used for system mounting. It is
recommended that the system be mounted at eye level to facilitate ease of
programming and operation.
There are three access holes on the right side of the unit. The top port hole is intended
for the system’s telephone line connection. The larger hole is intended for routing of the
system’s fault sensing leads, while the smaller hole is intended for the system’s power
supply transformer cable.
The following figure shows the recommended dimensions to be used in the physical
installation of the system.
3
D. BATTERY INSTALLATION
The battery is installed at the bottom of the system in the battery tray, provided as part
of the interior chassis assembly.
IMPORTANT!
Before installing the system battery, be certain the power supply transformer is not
plugged into an electrical outlet.
Remove the four phillips head screws which secure the system’s front panel and
remove it to expose the system’s interior. Note that the panel is still connected to the
system’s main circuit board, so care must be exercised while the panel is hanging on
this “tether”. Retrieve the red and black battery leads from within the battery tray. Push
the battery lead terminals onto 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.
Slide (do not force) the battery completely into the battery tray with the terminals pointed
DOWN into the system. If the battery is not completely seated in the battery tray, the
front panel will be obstructed and will not fit properly onto its mounting area.
A new battery will take no longer than 24 hours to gain a full charge, making it capable
of powering the dialer system through any power outage up to 6 hours in length. It
should be noted that the LOW BATTERY indicator is only valid when the 120 VAC
power is off. If the LOW BATTERY indicator stays on for more than eight hours, the
battery is in need of replacement
.
4
E. ELECTRICAL POWER INSTALLATION
Electrical power may be applied by simply plugging the system transformer into a
nearby electrical outlet. If the system’s environment has a history of, or has known
electrical power line disturbances, then use of a transient protection module, available
as an option from MICROTEL, is highly recommended.
If the unit is to be installed in a location where large or high voltage motors are in use, a
power line transient suppresser is also recommended to insure that the unit is not
affected by surges and spikes in the 120 VAC power to the unit.
It is recommended that a separate circuit breaker be used with the system. Remember
that when the breaker is on, and the unit is plugged in, 12 VAC is contained within the
system even though the system Power switch may be turned off. This is to allow
continued charging of the system’s backup battery, and retention of the system’s
message data, even with the system in a powered down state.
The internal system fuse is a 1 amp fuse (AGC 1), or equivalent. WHEN INSPECTING
OR REPLACING THE FUSE, UNPLUG THE SYSTEM OR THROW THE CIRCUIT
BREAKER SUPPLYING POWER TO THE UNIT.
5
F. TELEPHONE LINE INSTALLATION
The connection to the telephone network is a matter of simply plugging the modular jack
cable into the telephone line termination provided by the telephone utility (RJ-11C or
equivalent).
This section contains important information regarding the installation of the telephone
line to be used by the system, and pertinent information for notifying the telephone
company of what type of line is to be installed.
The Alarm dialer system is registered for direct connection to the telephone network by
the FCC, which placed three restriction on its use:
1. The system cannot connect to a party line or a pay telephone line.
2. The telephone company must be notified that an FCC registered device is being
installed.
3. If trouble is experienced with the device, it must be immediately disconnected form
the telephone network. Microtel must make any repairs which may be necessary
in order to maintain the FCC registration status of the device.
THE FOLLOWING INFORMATION WILL BE REQUIRED BY THE TELEPHONE
UTILITY WHICH INSTALLS THE TELEPHONE LINE FOR THE SYSTEM:
1. The FCC Registration Number, which is, D4J6M6-13598-AL-E.
2. The Ringer Equivalence, which is 0.2B.
3. The system needs to be connected to an RJ-11C telephone jack
.
6
G. FAULT MONITORING INTERFACE CONNECTIONS
The dialer system is designed to accept up to four channels of dry (unpowered),
normally open or normally closed signal lines. The system provides a small, pulsed
sampling current to determine if the contact is open or closed. Leads 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 pair on the Fault Input Terminal Strip. Shielded, twisted pair, 20 or 22 gauge
wire is recommended. Ground the shield at the sensor and leave the shield floating
(Disconnected) at the alarm dialer system.
Each channel may be configured to be either normally open or normally closed. A
channel will be normally open if the “no fault” (Green) condition consists of an open
circuit on that channel’s wire pair. A channel is normally closed if the “no fault” (Green)
condition consists of a closed circuit on that channel’s wire pair.
The programming section of this manual will provide details on how to program the
Mode (normally open or normally closed) of each channel as well as setting the Fault
Delay time for each channel.
Any unused channel should be left unconnected and programmed to a normally open
mode (Green)
.
7
H. POWERING UP THE SYSTEM
NOTE: IF THE UNIT ABOUT TO BE POWERED UP FOR THE FIRST TIME
CONTAINS HARDWARE FOR OPTIONAL FEATURES, READ THE
SUPPLEMENTARY INSTRUCTION MANUAL FOR THOSE FEATURES BEFORE
POWERING THE UNIT UP FOR THE FIRST TIME.
After the system has been mounted in a suitable area, the battery installed and power,
telephone and fault sensing lines connected, it may be powered up by switching the
POWER switch to the ON position. This switch is on the system’s front panel. When
the unit is powered up, the front panel indicators will flash in sequence [reset flash] for a
few moments. If this does not happen, turn the switch to the OFF position, disconnect
the power and the telephone line from the unit. Contact a qualified service person or
Microtel, Inc. for instructions.

II.
For this section, the key stroke entries are CAPITALIZED. The system’s response,
whether visual or audible, are enclosed within [BRACKETS].
The system must be in the Halt mode [Red run light] to accept programming
information. If it is not in the Halt mode, depress the HALT key to force that condition.
[reset flash]
A. FAULT MODE PROGRAMMING
The fault status of each of the five channels is shown as a fault (RED) or no-fault
(GREEN) condition on the corresponding front panel indicator. The system allows the
user to specify whether an open contact condition should be regarded as a no-fault
(GREEN), or as a fault (RED) state. To program each channel, first apply a known fault
contact state to each input. This means shorting the input if a normally closed contact
mode is to be used, or opening the input connections if a normally open contact mode is
to be used. The 250 Real Voice system allows you to train the input for the proper
mode choice.
For each fault input channel, perform the following programming steps:
1. ENTER, MODE, No.(1,2,3, or 4)
[indicator No. will flash, verifying selection]
2. The selected indicator will alternate between RED and GREEN at one second
intervals. When the indicator for the channel being programmed is in the
proper state (RED or GREEN) for the applied input, depressing ENTER again
will select that mode.
To verify the proper mode, simulate the opening or closing of the fault input contacts
and view the proper state indication (RED or GREEN) on the system front panel.
B. FAULT DELAY TIME PROGRAMMING
Each channel may be programmed for its own fault delay time response, from 1 to 99
seconds. This means that the system will neither display or respond to a fault channel
changing from a no-fault to a fault condition for this time period. Changes from a fault to
a no-fault condition are, however, instantly detected by the system.
The 250 Real Voice system allows the user to train the fault detection sequence to set
the desired fault detection delay.
PROGRAMMING THE DIALER SYSTEM
9
To program the Delay Time for each fault channel (Channels 1, 2, 3, and 4) and the
Power Fault channel (Channel 5), perform the following programming steps:
1. ENTER, DELAY, No.(1, 2, 3, 4, OR 5)
[Indicator No. will flash, verifying selection]
2. Indicator will flash once each second. When the desired delay time has
passed, depressing ENTER again will set that time period for that fault
channel.
To verify the proper delay time, simulate the opening or closing of the fault input
contacts and view the proper state indication (RED or GREEN) on the system front
panel. The fault channel will change from a GREEN to a RED state after the
programmed delay. It will change from a RED to a GREEN state almost immediately
upon detection of a no-fault state.
To read the Fault Delay for each channel, the following steps should be performed.
1. READ, DELAY, No.(1, 2, 3, 4, or 5)
[fault No. indicator will flash once each second, for each second programmed]
C. FAULT MESSAGES
The system allows the user to program messages for each event which the system
must respond. The unit is shipped with no speech programmed and must be loaded
with messages after installation. Voice data is retained using the system battery
installed in section 1-D. The following messages must be entered by the user:
Location Purpose
0 The message indication system or station location
1 The fault message for channel 1
2 The fault message for channel 2
3 The fault message for channel 3
4 The fault message for channel 4
5 The fault message for channel 5 (AC Power Failure)
6 The message for Status Normal --No faults
7 The message used after proper acknowledgment, before entering intercall
delay
The system reserves 4 or 8 seconds of message time for each message. The
programming sequence used determines the amount of time allotted. Additionally, fault
messages may be programmed as a “Status Only” channel as described below.
10
The following programming steps should be performed for the creation of fault channel
messages:
1. ENTER, MESSAGE, No.(0, 1, 2, 3, 4, 5, 6, or 7)
[indicator or combination of indicators will flash, verifying selection]
2. Depress ENTER for a normal 4 second message, or depress # for an
extended length (8 seconds) message, or depress * for a “Status Only”
assignment message.
[Message In Process Indicator will turn on, indicating recording is in process].
Begin speaking message. It is necessary to speak directly at the
microphone, at a distance of approximately 8 inches. This will minimize
background noise which would be picked up by the microphone as part of the
message. It is also necessary to turn off loud equipment in the vicinity of the
system while recording messages, to maximize clarity.
3. After the expiration of the message time limit, Message In Process Indicator
will go out, and the message just programmed will be played back for
verification.
To read or verify the message for each channel,
1. READ, MESSAGE, No.(0, 1, 2, 3, 4, 5, 6, or 7)
[programmed message will be spoken by the system]
Sample messages are located in Section IV. C.
Status Only Channel Programming
Any fault channel may be programmed as a “status only” channel as shown above (i.e.
it will not cause call-outs to begin, but will be reported in any status messages).
D. PROGRAMMING TELEPHONE NUMBERS
The system can be programmed with up to eight telephone numbers, which will be
called sequentially when an abnormal condition is detected by the system on any fault
channel not programmed as a “status only” channel. The following programming
procedure should be performed to enter telephone numbers into the system. Note that
there must be at least one telephone number programmed into the system for it to
operate at all. All eight telephone number data locations need not be programmed.
11
Telephone numbers may be deleted by entering a “0” into the data location for that
number in the list.
1. ENTER, No. (1, 2, ...8)
[indicator or combination of indicators will flash verifying selection]
2. Enter the desired phone number by depressing the numbers on the keypad.
3. Terminate the entry with a second depression of ENTER.
To read this data for verification,
1. READ, No. (1, 2, ...8)
[telephone number No. will be dialed by the system. Test call may be
terminated by depressing HALT]
Up to 16 digits may be entered for each phone number position. If any of the numbers
the unit is to call require a pause for a second dial tone, enter the pause by using the
DELAY key in place of a digit.
To clear a phone number out of the unit, enter a 0 (zero) as the phone number. The
unit ignores any phone number that starts with a 0. If you wish to have the unit call the
Operator, enter the phone number as DELAY, 0.
E. OPERATIONAL PARAMETERS
This section describes the procedure for setting 4 operational parameters. All of these
parameters are entered into the system using the system’s programming keypad.
1. Setting the Ring Count
The ring count is the number of rings the unit will wait before answering a call placed to
it. This may be set to any number of incoming rings from 1 to 99.
1. ENTER, *
[indicator will flash]
2. Enter a two digit number for 01 to 99 representing the desired ring count.
2. Tone or Pulse Dial Selection
The system needs to be set for pulse or tone type dialing. Perform this selection by
following these programming steps. Before programming the unit to function in a tone
12
dialing mode, confirm with the telephone company that services the installation that the
line to which the unit is connected to will accept tone dialing.
1. ENTER, MODE, 0
[indicator will flash]
2. Enter “0” for pulse type dialing, or “1” for tone type dialing.
To verify the dialing mode, cause the system to test dial by selecting
1. READ, No.(1, 2, 3, 4, 5, 6, 7 or 8)
[telephone number will be dialed]
3. Message Repetitions
The system will repeat its fault status message a number of times in the course of any
telephone call which it places. The system is shipped programmed to repeat the
message 8 times during each call. If it is necessary to change the number of times the
message if repeated, perform the following programming steps.
1. ENTER, #
2. Enter a two digit number corresponding to the desired number of message
repetitions (01 to 99).
To verify this data, test dial a number and listen to the number of message repetitions
before the system terminates the call attempt.
4. Intercall Delay
When a call placed by the system is acknowledged, (see section III.C for the
acknowledgment procedure) it will delay further calls for a programmable period to allow
time for the condition to be corrected. The time delay period following an acknowledged
call is called the intercall delay. The unit is shipped with this delay set to 1 hour. It may
be from 1 to 99 hours and is programmed at the system keyboard as follows.
1. ENTER, DELAY, 0
[indicator will flash]
2. Enter a two digit number corresponding to the desired number of hours of
delay.
(Values less than 10 hours must be entered with a leading 0,
Example: 01= one hour)
13
5. Delay Run Programming
The Run Mode may be entered after a programmable delay.
1. DELAY, RUN
[indicator will flash]
2. Enter the desired two digit delay in minutes (01 to 99 minutes)
(Values less than 10 minutes must be entered with a leading 0,
Example: 01= one minute)
The flashing Run indicator verifies that the system is in the delayed run mode. After the
delay is completed, the system will enter the Run Mode and the Run indicator will stay
on. (Green)
14
III. OPERATIONS
A. SYSTEM FAMILIARIZATION AND KEY FUNCTION SUMMARY
The power switch for the system is located on the Front Panel of the system. It is
important to note that when power is connected to the system, and the switch is in the
off position, it does not remove power from the unit. Power is always present unless
the circuit breaker (which the INSTALLER must supply) is turned off or the transformer
is removed from the A/C outlet.
There are six indictors across the top side of the keyboard assembly on the front panel.
These LEDs will indicate the state of the fault channels which the system is intended to
monitor, indicating RED for fault condition and GREEN for a no-fault condition. A
system status indicator displays RED for the HALT mode and GREEN for the RUN
mode.
On the left side of the system front panel is the system speaker. This speaker allows
words the system synthesizes to be heard, as well as telephone line sounds when the
system is on the telephone line placing an alarm call or during a status call placed to the
system.
A Description Of Each Of The System’s Keys And Their Functions Now Follows:
HALT
The HALT key will abort any operation in process, and return the system to the Halt
mode as indicated by the RED RUN STATUS indicator. In this mode, fault conditions
will not be acted upon by the system. However, it is still possible to call the system.
The system will answer the call and deliver the appropriate status message.
RUN
The RUN key will place the system in a run mode as indicated by the RED RUN
STATUS indicator. If fault conditions exist, the system will begin placing telephone calls
(if valid telephone numbers have been programmed into the system). Use of the Delay
key in conjunction with the RUN key will cause the system to execute a delayed entry
into the RUN mode -- which may be programmed to be up to 99 minutes (see the
section entitled “Putting the System in Run” later in this section for more information on
this feature).
MODE
The MODE key is used in conjunction with other keys to effect certain features in the
system programming, including fault modes and tone/dial selection.
15
SEQUENCE
The SEQUENCE key is a preface key which allows some of the advanced operation
features of the system to be activated. Until the purpose and use of this key is
explained later in this manual, it is advisable to leave it alone. If this key is randomly
operated with others, an unintentional yet valid keystroke combination could occur,
deleting portions of programmed telephone numbers and other data.
ENTER
The ENTER key is used to enter data which the system must use in performing its
monitoring and alarming functions. Included in this data are telephone numbers, fault
messages, the system identification message, the message count, and the intercall
delay.
MESSAGE
The MESSAGE key is used in conjunction with others to program the message for each
fault channel, and the system identification message. Additionally, depression of the
MESSAGE key alone when the system is in the HALT mode, will cause the current ID
and status messages to be articulated by the system.
READ
The READ key is used to recall any of the programmed information.
DELAY
The DELAY key has four functions:
1. When used in telephone number programming, it inserts a short pause
between digits in a telephone number.
2. When used with the ENTER key, (i.e. ENTER, DELAY, 0) it sets the intercall
delay time; that is, the time the system will wait after its call out message has been
acknowledged before it begins placing regular calls again (see section II E-4 of this
manual for additional information).
3. When the DELAY key is used with the RUN key, (DELAY, RUN) it allows
delayed, automatic entry into the RUN mode.
4. When the DELAY key is used for fault delay time programming, it allows the
entry of integration or delay times for the detection of each fault condition.
DIGITS 1 THROUGH 0
The digit keys are used for numeric entry of data values and data locations.
* KEY
The * key is used as an entry location for ring count programming. The ring count is the
number of incoming telephone rings which the system will count before answering and
servicing the incoming call. (See Section II E-1 of this manual for more information)
16
Additionally, the * key is the key used over the telephone for acknowledgment of the
system call out message. It is also useable locally (on the system keyboard) for
acknowledgment right at the system.
# KEY
The # Key is used as an entry location for the message count. This is the number of
times that the entire fault status message is repeated in the course of each telephone
call placed by the system. (See Section II E-3 of this manual for more information).
B. PUTTING THE SYSTEM IN RUN
After all operational data has been entered into the system, the unit is ready to enter the
run mode. Once in the Run mode, any fault channels will be acted upon causing calls
to be placed to the programmed telephone numbers.
To place the system in the Run Mode, depress the RUN key on the system’s front
panel. The Run indicator will verify successful entry into the Run Mode. (Green)
Delayed Entry into the Run Mode
The Run Mode may be entered after a programmable delay.
The flashing Run indicator verifies that the system is in the delayed run mode. After the
delay is completed, the system will enter the Run Mode and the Run indicator will stay
GREEN.
C. RECEIVING AN ALARM
When a valid alarm condition is recognized by the system, it will be indicated locally on
the system’s front panel. If the system is in the Run Mode, it will immediately begin
placing telephone calls to the telephone numbers which have been programmed by the
user.
Upon the receipt of an alarm call, the answering party will hear the station identification,
followed by the current status messages. This entire message will be repeated the
number of times programmed. If the entire message sequence is completed without an
acknowledgment being returned over the telephone line, the system will terminate the
1. DELAY, RUN
[Indicator flash]
2. Enter the desired two digit delay in minutes (01 to 99 minutes)
(Values less than 10 minutes must be entered with a leading 0,
Example: 01= one minute)
17
call, wait 70 seconds for a call back acknowledgment, and then place a call to the next
telephone number in the list. If an acknowledgment is not received from the next call
after another 70 second wait, a 3rd call will be placed, and so on. The unit will continue
to call repeatedly from the user’s programmed list of telephone numbers until it receives
an acknowledgment or the fault condition is removed.
If the system is acknowledged during the call, it will not place any further calls for a time
programmed as the Intercall Delay. If a new fault condition occurs during that period,
the Intercall Delay will abort and calls will begin again. If the entire Intercall Delay
expires and the fault conditions still persist, the system will again begin to place
telephone calls.
To Acknowledge a Call From the System
Acknowledgment may be accomplished by depressing the * key on the called telephone
between message repeats during the alarm call. The * key must be depressed for at
least 2 full seconds but not longer than 5 seconds. The system will verify that the
acknowledgment has been accepted by saying the recorded voice message for proper
alarm acknowledgement [Voice message 7].
If acknowledgment must be returned from a telephone without tone capability, the
system may be acknowledged by placing an immediate call back to the system, within
60 seconds after it has completed its call. Again, the system will verify that the
acknowledgment has been accepted by saying, [sign off message, in location number 7,
as programmed above, will be recited].
D. TEST AND ADVANCED KEYSTROKE SEQUENCES
A number of sequence commands are possible on the system’s front panel keyboard.
They are as follows:
SYSTEM LEVEL TEST SEQUENCES
SEQUENCE 50
[all messages are recited]
SEQUENCE 52
[flash test all front panel indicators] (HALT to terminate this sequence)
SEQUENCE 55

IV MAINTENANCE AND TROUBLESHOOTING
In the unlikely event that trouble is suspected with the system, it must be promptly
disconnected from the telephone network, and referred to Microtel Inc. or its authorized
service representatives.
Periodically inspect the system internally for any evidence of moisture, blown fuses, or
battery failure as instructed herein.
A. MAINTENANCE
1. Battery Care
Battery life is dependent upon a number of factors, and will vary depending on the
number of outages, and the age of the battery. A new battery will take no longer than
24 hours to gain a full charge, capable of powering the system through any power
outage up to four hours in length. It should be noted that the LOW BATTERY indicator
is only valid when the 120 VAC power is off. If the LOW BATTERY indicator stays on
for more than eight hours, the battery is in need of replacement.
2. Battery Replacement
The battery is installed at the bottom of the system in the battery tray, provided as part
of the interior chassis assembly.
NOTE: It is necessary to remove all power from the system before replacing the
battery.
Refer to Section 1-D - Battery Installation for instructions on installing a new battery.
3. Volume Adjustment
The volume of the system’s speech messages delivered to the telephone network is
fixed. The volume of the speech heard through the system speaker is, however,
adjustable by varying the setting of potentiometer R21, located on the main circuit card
in the unit.
4. Acknowledge Tone Adjustment
R33, located on the system’s main board, is the adjustment for the frequency detected
during the acknowledgment of an alarm call. By activating SEQUENCE 55 (see
previous section) the system will deliver a continuos acknowledge tone (* key) to itself,
during which the potentiometer R33 may be set. Center the adjustment by varying the
setting until the Acknowledge LED on the front panel turns on. There is some amount
of hysteresis associated with the detection so the centering of the component must take
into account approached from each direction. The continuous tone used for adjustment
may be halted by depressing the HALT key after the adjustment is completed.

E. WARNING
Battery circuits remain active at all times. The potential exists for the battery to
discharge to a point where the battery cannot be recharged. To prevent an
unrecoverable depletion of the internally mounted battery, it is suggested that prior to
storage of the dialer unit or in the event of a prolonged interruption of 120 VAC power,
the internally mounted battery be disconnected. Disconnection is accomplished by
removing the wire termination spade from the positive (+) battery termination point
located on the battery.
Battery disconnection should also occur upon low battery indication as detected and
enunciated by the dialer unit and remain disconnected until 120 VAC power can be
restored.
Disconnection of the battery in an unpowered condition will require reconfiguration of
the units prior to placing the units back into service.
