The Microtel CellStatTM features a single level, interactive command structure--there are
no multi-level menu structures to navigate. Commands are sent to the dialer through your
telephone either locally or during a call to or from the dialer, by pressing a sequence of
touch-tones on your telephone. Each command entered is acknowledged with a spoken
response from CellStatTM, providing verification that the command was entered correctly
and understood by the dialer.

About this Manual: This manual is organized with the most crucial information in

the front; more advanced topics are saved for last or included in the appendices.

Who Should Read this Manual: Anyone involved with use of the dialer should

read the General Description and Operation chapters of the manual. The Operation
chapter in particular should be read by any personnel who may be required to respond to
alarm calls from the dialer. The additional chapters can be read at a later time, or when
necessary by authorized personnel to maintain the dialer or troubleshoot any problems
you might encounter. System administrators should read the Advanced Topics chapter
for information on the use of the dialer’s remote software configuration capabilities.

Theory of Operation

How Does the Dialer Work?

asking a few questions about typical use of the dialer. The following paragraphs assume
the dialer is hooked up and running as described in the Installation chapter. The
Operation chapter provides the details that are missing from the discussion below.

What Happens when an Alarm Occurs? CellStat

up to eight people, answering machines, or pagers to call in the event of an alarm. It can
also transmit an email alert to an optional email address, or an alarm log to the optional
Microtel Log-Stat™ web application, via its built-in cellular communications capability.
When an alarm occurs, the dialer will first log the event to the user-specified email
address and/or Log-Stat™ web-based application, then begin to place a series of
telephone calls over the telephone line or built-in cellular module, or both, in an attempt
to have someone acknowledge the alarm.

The dialer reports the current alarm status when an outgoing call is answered. It repeats
the message several times while listening for a touch-tone being entered on the remote
phone.

How does an Alarm get Acknowledged? An alarm can be acknowledged in

three ways:

1) Entering the '*' key on your touch-tone phone during message playback.

2) Calling back the dialer immediately after it calls you or sends you an SMS text

message alert (callback acknowledge). This feature is necessary if the called party
does not have a touch-tone phone, or the dialer sent an SMS text message alert.

3) The dialer will automatically acknowledge a successful call to a pager, answering

machine, or P.A. system if the telephone number is embedded with an auto
acknowledge code. (See chapter 5, Advanced Topics).

What if I’m not Home? The Call Progress Decoding features of the dialer allow it

to determine if the called telephone number is busy or did not answer. In either case, the
dialer will wait 10 seconds before placing a call to the next number on the calling list.
Calls to mobile phones will usually roll over into a voice mailbox if the mobile phone is
not answered. In this case, the dialer will record a spoken alarm report, and treat the call
as answered but unacknowledged.

When the dialer is off-hook, it has the capability to detect dial tone, busy, ringback, and
voice signals. This allows it to detect if a called party answered or not, thus reducing the
time to alert authorized personnel of existing alarm conditions. If a call is not answered,
or the called number is busy, the dialer will abort the call and begin calling the next
number on the system telephone list.

This section provides a simple theory of operation by

TM

has a telephone directory of

7

MICROTEL CellStatTM

Will the Dialer Call Me Back? Maybe. The dialer has a snooze timer. When an

alarm is acknowledged, the snooze timer is started, and alarm calls for all acknowledged
faults are suspended. If a channel is still in alarm after the snooze period ends, then the
dialer will begin a new alarm dialing sequence (starting with logging the event to the
email address, then calling the first number on the telephone list).

How does the Dialer Know Who to Call? The dialer has a System Telephone

Directory composed of up to 8 user-programmed telephone numbers. It also can store a
single email address. Each telephone number in the System Telephone Directory can be
up to 30 digits long, and can specify whether the call is placed over the hardwired
telephone line or via the built-in cellular module. Special ‘*’ control sequences may be
embedded within a user-programmed telephone number. These include tone/pulse
selection dialing, pauses, auto acknowledgment of an alarm call-out, dial '*' or '#' for
interfacing to telephone equipment, or to select the built-in cellular capability to make the
call or send a text message alert. These special sequences allow a tremendous amount of
flexibility on a telephone number by number basis. For example, one number may pulse
dial out on the hard-wired telephone connection, while the next may use the built-in
cellular module to transmit an SMS text message alert.

How does the Dialer Prioritize its Calls?

When the dialer detects a new alarm condition, it will search the telephone directory,
beginning with the first number on the list, for the first valid telephone number. The
dialer will then go off-hook (or use the built-in cellular communications if the phone
number has a *70 code indicating the dialer should dial out using the cellular interface)
and begin to dial the telephone number if the following conditions are true:

1. The Call Spacing Timer = 0, and the dialer has been on-hook for at least
the network recovery time (10 seconds).

2. The local telephone is on-hook (OFF HOOK LED is OFF).

3. The telephone line is operational (dial tone is detected), OR, if a cellular call,
there is sufficient balance in the cellular prepaid account to make a call.

During the dial out sequence, the dialer will implement all special control sequences
and/or call progress features embedded within the current telephone number. If the dialer
successfully connects with the called number, it will speak the alarm message for each
fault condition which exists.

On a voice callout, the dialer will repeat the alarm message five times after a call is
answered. While speaking the alarm message, the dialer simultaneously listens for a
touch-tone entered by the user at the remote phone. If it receives a valid tone, it will
terminate alarm reporting, and examine the tone received. If the user entered a ‘*’ key,
the dialer will accept it as an acknowledgment of the alarm condition. Any other keys
received will not acknowledge the alarm condition. The dialer will then indicate the
acknowledge status and prompt the user to enter a 2-digit access code.

8

MICROTEL CellStatTM

If the user enters the correct code, access will be granted and the user may review or
program the dialer’s configuration using the touch-tone commands described in this
manual. If at any time during remote menu access the user does not enter a command
within 30 seconds, the dialer will speak a disconnect warning and hang up.

If an incorrect or no access code is entered during a timed access code entry time (10
seconds), the dialer will disconnect and initialize the system Call Spacing delay timer. If
the alarm condition(s) were acknowledged, then the snooze timer(s) associated with the
reported alarm condition(s) will be initialized with a value equal to the programmed
system Snooze Delay. If alarm conditions were not acknowledged, calls will continue to
be placed to the next telephone numbers on the list after the system Call Spacing delay
has expired.

How can I Make an Alarm Sound in the Vicinity of the Dialer?

The local summary alarm contacts can be configured (default) to be de-energized
(opened) whenever a fault condition exists. This output could be connected to an
interposing relay whose contacts would be used to switch a siren or bell to warn the local
area of the alarm condition.

procedure which summarizes the configuration procedure of the dialer.

I

Step One - Connect the Power Supply Connect the supplied external

transformer to the 12 VDC terminals as shown in Figure 2 below. Plug the transformer
into a MicroMax Surge Suppressor (Recommended by Microtel).

involves several, simple steps. This chapter outlines the

Figure 2. Power Supply Connection

NOTE: Alternatively, you may connect any 12 to 20 Volt DC power (such as a solar
panel) to the dialer. Connect the positive side of the voltage source to 12VDC+, and the
COMMON lead to 12VDC- of the power supply terminal block of the dialer.

NOTE: Although the dialer will operate and place telephone calls when operating on its
standby battery, external power must be present whenever you wish to configure/query
the dialer from the local phone PHONE jack.

10

MICROTEL CellStatTM

Step Two - Telephone Connections (Optional) include the external phone line

for call-outs and the optional local telephone connection for local programming and
monitoring. If only the built-in cellular interface is to be used, then no telephone
connections are necessary.

CAUTION: This equipment cannot report an alarm when other equipment (telephone,
answering system, computer modem, etc.) connected to the same phone line is in use.

1. Connect the dialer’s LINE jack to the EQUIPMENT Phone jack of the MicroMax
Surge Suppressor using the cable supplied with your dialer.

2. Connect the Telephone LINE jack on the MicroMax Surge Suppressor to the RJ11
jack of your outside line using the cable supplied with the MicroMax Surge
Suppressor.

3. Connect a local telephone (optional) to the dialer’s PHONE jack.

NOTE: Telephone line transients and surges can damage the dialer or disrupt its
operation. We recommend use of the MicroMax Surge Suppressor for normal operations.

Step Three - Cellular Connection

calls to/from the dialer wirelessly, then ensure the antenna is screwed onto the bulk-head
mounted female SMA connector on the upper left-hand-side of the enclosure, shown in
Figure 3 below. Do not over tighten--finger-tighten only!

Alternatively, a remote antenna can be mounted on the external surface of an enclosure
(Required if the dialer is mounted within a metal cabinet), and a female-to-male SMA
extension cable can be screwed to the bulk-head mounted SMA connector, then routed to
the remote antenna. Again, only finger tighten the SMA connections.

If using the built-in cellular interface to place

Figure 3. External Cellular Antenna Connector

MICROTEL CellStatTM

Step Four - Connect External Input/Output to the Dialer Each Fault input

has a corresponding terminal (1 - 4), and there are two COM terminals. See Figure 4
below. The terminals are large enough to accept two 14 AWG wires, so if more than two
faults are wired, the COM terminals must be shared. The fault sensing circuitry is
transformer and optically isolated from the dialer circuitry, but all faults share the same
COM. Use 22 AWG shielded twisted pair wire when wiring external sensors to the I/O
terminals. Whenever possible, ground the shield at the sensor end only
wires should never share conduit with AC power wiring.

The local alarm contacts are normally energized, and closed. When a user-defined alarm
condition exists these contacts are opened (de-energized). These contacts may be used to
drive a low power (10 volt-amps Max.) resistive load, or as a signal to another piece of
process-monitoring equipment. High power and/or inductive loads must be driven from
an external power relay. The local alarm contacts are suitable for driving a 12 – 48 volt
DC relay coil.

NOTE: Keep I/O runs to a maximum length of 150 ft.

Quick Start Procedure

This procedure outlines the steps to get the CellStatTM dialer operating in a typical
manner with a minimum of programming.

1. Plug the touch-tone telephone into the Dialer PHONE jack.

2. Connect external 12 VDC transformer to dialer power supply terminal block.
NOTE: External power required in order to configure the dialer from a local phone.

3. Verify that the AC POWER/CHARGING LED illuminates (green).

4. Turn ON the dialer switch. Wait about 30 seconds for the dialer to complete its power
on initialization sequence. Take the telephone off-hook. The OFF HOOK light
should be illuminated (yellow) indicating the unit is ready to accept touch-tone
commands from the local telephone.

5. Press the # key of your telephone. The Dialer will respond “Ready.”

NOTE: To start over, press the # key and listen for CellStat

6. Enter Telephone Numbers to Call upon Alarm.
z Enter **6np**, where n = 1,2,3,...8, is the dialer’s directory index of telephone

numbers, and p is the actual telephone number (including optional escape codes
of up to 60 digits). Example: The second phone number of the directory is 555-

1212. Enter **62 5551212**.

z The Dialer will respond, “Telephone number two is 5551212.”
z To cause the dialer to use its built-in cellular communications to make a voice

call, enter a *70 at the beginning of the telephone number. To cause an SMS text
message report to be sent, enter a *71 at the beginning of the telephone number.

7. Configure Input Normal States
z Enter **c3n, where c is the I/O channel (numbered 1 to 4 from left to right) and n

= 1 for NORMALLY OPEN, or 0 for NORMALLY CLOSED.

8. Record System and Alarm Voice Messages

System ID Voice Message:

z Enter **01 to record up to a 10 second system voice message. The dialer will

respond “Ready”.

to speak, “Ready.”

z Speak your message clearly into the handset.
z The dialer will speak back the message after the 10-second recording interval.
z Repeat as necessary until you are satisfied with the recording.

13

MICROTEL CellStatTM

Individual Channel Alarm Messages:

z Enter **c1 to record an alarm message for a specific I/O channel. (c = 1 to 4 for

the I/O channel of interest). The dialer will respond “Ready”.

z Speak your message clearly into the handset.
z The dialer will speak back the message after the 6-second recording interval
z Repeat procedure for the next I/O channel and message.

9. Verify Configuration Data is saved in the Dialer.

Enter *00 and listen to the spoken status report. If you are using the built-in cellular

communications of the dialer, ensure that the spoken status report indicates there is
sufficient signal power and prepaid balance. If the cellular prepaid balance falls
below $5, the dialer will place calls to report this condition.

10. Important: Test the dialer by causing an alarm condition. Verify ALL the
programmed telephone numbers are successfully called in order to ensure the dialer is
operating properly and can successfully report an alarm condition. Periodically,
retest to continue to ensure the dialer is operating correctly.

WHEN PROGRAMMING EMERGENCY NUMBERS AND(OR) MAKING TEST

CALLS TO EMERGENCY NUMBERS OVER THE PUBLIC TELEPHONE LINE:

1) Remain on the line and briefly explain to the dispatcher the reason for the call.

2) Perform such activities in the off-peak hours, such as early morning or late

evenings.

navigate. Commands are sent to CellStat
during a call to or from the dialer, by pressing a sequence of touch-tones on your
telephone. Each command entered is acknowledged with a spoken response from the
dialer, providing verification that the command was entered correctly and understood by
the dialer.

All programming commands (commands that modify dialer configuration or cause an
action to occur) begin with ‘**’ (two stars). All review (report) commands begin with a
‘*’ (single star). After each command is entered, the dialer will respond with a voice
message. Most commands require exactly the same number of keys every time, but some
commands have a variable data length. The end of variable length data commands is
performed with the ‘**’ (two stars).

NOTE: An unwanted command can be terminated at any time by pressing the ‘#’ key.

NOTE: The optional email address is configured/queried by sending an SMS text

message from a mobile phone to CellStatTM’s cellular phone number. All other
configuration of the dialer is done using touch-tone commands from either a local or
remote phone.

Throughout this manual, all commands are highlighted for quick reference as follows:

MICROTEL CellStatTM

A new channel name can be recorded with the '**c1' command. Once the command
is typed record your voice message after the dialer prompts you “Ready”. A
maximum of 6 seconds of recording time is allowed for each fault input message.

z I/O Channel Fault Delay When channel c changes state, this timer delays an alarm

until the channel has been in the alarm state for (SS) seconds. This parameter will
filter out noisy, or temporary, state changes from placing undesired nuisance alarm
calls. During this fault delay period, the corresponding CH LED indicator will turn
yellow, indicating that the input channel is NOT in its normal state, but has not been
in the state long enough to cause an alarm callout. After the delay has elapsed, and
the fault state condition still exists, the corresponding CH LED will turn RED and
begin flashing.

*c2 Report I/O channel c delay
**c2SS Program I/O channel c delay

Example- Command: **1230

Response: Channel one fault delay is three zero seconds.

z I/O Alarm Configuration Selection of channel c normal state (OPEN or

Telephone Numbers

As described in the theory of operation in Chapter 1, CellStatTM can store up to eight (8)
phone numbers in the System Telephone Directory. This section explains how to
program the dialer’s telephone numbers and shows how to customize the numbers for
certain call-out situations.

Use the following command to enter each telephone number into CellStatTM:

*6n Review Telephone n (n=1 to 8)
**6np** Program Telephone n (n=1 to 8)

p = telephone number of up to 30 digits with escape codes for one of 8 (eight) telephone
numbers. The telephone data is terminated with ‘**’ (two asterisks).

Example- Command: **61 2760571**

Response: Telephone number one is two seven six zero five
seven one.

Phone number dialing may be customized on a number-by-number basis. Refer to the
Advanced Topics chapter for using the powerful features of the CellStatTM Dialer.

Setting the Email Address

CellStatTM has the capability to store a single user email address. Upon a new alarm

detection, CellStat

Operations

This section details operation of the dialer, from both local and remote locations.
Sections will detail the following actions:

z Alarm Acknowledgment
z Checking System Status
z Using the Log-Stat™ web-based application
z Controlling the local output relay

Alarm Acknowledgment

When CellStatTM calls you, you may wish to respond to the call differently depending on
what type of alarm has occurred, who is on duty, the time of day, severity of the alarm,
etc.

If you wish the dialer to go to the next phone number on its calling list, hang up the
phone. The dialer will continue on after the call spacing delay to the next phone number
on the list until it receives an acknowledgment or the unlatched alarm goes away by
itself.

If you wish to acknowledge the call from your touch-tone phone, press the ‘*’ key on
your telephone while the alarm message is being spoken. The dialer will respond by
speaking, “Acknowledged”. If you then need access to the remote programming
commands, enter the 2 digit access code when CellStat
access to the dialer, you may review or modify any of the dialer’s configuration data.

NOTE: If you don’t have a touch-tone phone, or if you received an SMS text message

alert from CellStatTM, you can acknowledge the alarm call by calling the dialer
back within the call-spacing period (one to three minutes). When the dialer
answers the telephone call, all fault conditions will be acknowledged.

Checking System Status

CellStatTM allows easy checking of system status and capability. Spoken reports of your

entire remote-monitored system can easily be generated, or SMS text message status
reports can be retrieved via the dialer’s built-in cellular capability.

A spoken system status report can be received from the dialer by entering the following
command from a touch-tone telephone either locally, or remotely after answering or
calling the dialer. The dialer will speak a voice message of system name and current
alarms or normal status. It will also report the current cellular signal strength, remaining
balance in the prepaid cellular account, temperature, and local output state IF the local
output has been manually controlled.

z System Status Gives a complete status of all points monitored by the dialer

*00 Report system status

Example- Command: *00

Response: MICROTEL CELLSTAT Channel one normally closed

digital input in alarm. Cellular power is normal. Cellular
balance is one one point six four dollars ($11.64).
Temperature is seven eight degrees. The local output is
open.

Alternatively, an SMS Text Message report of system status can be retrieved by sending
the following text message from a mobile phone with text message capability:

“stat” Report system status via SMS Text Message

Example- Command: “Stat”

Response: “CellStat(TM)
Channels in Alarm:1,
Cellular power: normal.
Cell balance: $11.64
Temp: 78 (74, 78) F
Output: OPEN”

NOTE: When entering the “Stat” text message, do NOT type the “” marks.
NOTE: Display formatting on your

mobile phone may be slightly different.

Using the Log-Stat™ Web-based Application

22

MICROTEL CellStatTM

CellStat™ can be configured to log all alarm events wirelessly to Microtel’s optional
web-based application, Log-Stat™. Upon a new alarm detection, CellStatTM can
wirelessly transmit an event log to Log-Stat™ via its built-in cellular capability before it
begins calling the phone numbers on its list. This capability provides the benefit of an
electronic record of each and every alarm event that occurs, accessible from any web
browser. Additional, more-descriptive email notifications can be sent from Log-Stat™,
and log data can be exported to an Excel spreadsheet.

Log-Stat™ event logs are only sent via the built-in cellular capability, not over the
telephone line.

In addition to event logging, when the dialer has Log-Stat™ capability enabled it
transmits a weekly health status report to Log-Stat™. This weekly health status report
will be forwarded to any email address(es) that are configured in Log-Stat™.

The dialer can be queried to check whether Log-Stat™ web-logging is enabled by
sending the following SMS text message from a mobile phone to CellStatTM’s cellular
phone number:

“log-stat” Query the current Log-Stat™ capability via SMS Text Message

Example- Command: “log-stat”

Response: Enabled

NOTE: CellStatTM’s built-in cellular phone number is printed on a label on the left side
of the enclosure, near the antenna.
NOTE: Do not type the “” marks.

Log-Stat™ web-logging can only be turned ON by the factory. Call Microtel to order.

CHAPTER 4 - Maintenance/Troubleshooting

he CellStatTM Dialer is built to require minimal maintenance. Only the system
battery requires your attention from time to time for your dialer to continue

T

INTERNAL RECHARGEABLE BATTERY: A battery in typical standby use

will last approximately 2 to 4 years. Battery life is mostly dependent upon the number of
power outages sustained, the age of the battery, and temperature. A new battery should
take no longer than 72 hours to gain full charge, capable of powering the system through
a power outage of 16 - 24 hours. Battery backup time may vary depending upon the age
of the battery and the frequency and duration of alarm callouts which occur while the
dialer is operating on the standby battery..

FUSE: CellStat

you can measure 12 – 20 VDC at the external power input terminal block, but the AC
POWER/CHARGING LED is OFF, the fuse may have blown. Remove power from

CellStatTM by turning OFF the Power switch and unplugging the removable External

Power Terminal Block. Wait for about a minute for the fuse internal to the dialer to cool
down, then plug the power back in. If the AC POWER/CHARGING LED comes ON
briefly then goes OFF, the fuse is blowing. Blown fuses can be indicative of other
problems. Measure the input power supply, and verify that it is 12 – 20 VDC. A high
external voltage may cause the fuse to blow. If the fuse continues to blow and the
external power is within specifications call the factory.

CELLULAR PREPAID ACCOUNT:

from either Cingular or T-Mobile. The remaining balance in the prepaid account can be
determined by querying the dialer with the *00 Report System Status command. The
dialer will speak the current cellular signal power level as weak, normal, strong, or none;
as well as the remaining balance, in dollars, in the cellular prepaid account.

Alternatively, this information can be queried from the dialer by sending a “Stat” SMS
text message from your mobile phone to CellStatTM’s cellular phone number. CellStatTM
will respond by sending an SMS text message of current status back to your phone.

If the prepaid balance ever falls below $5, the dialer will begin placing calls to all the
telephone numbers to report this as an alarm condition. On the upper left-hand side of
the dialer enclosure, near the cellular antenna, is a label that indicates the cellular carrier
and phone number of the dialer (See Figure 3 in CHAPTER 2 -- Installation). When it is
time to replenish/top-up the prepaid cellular account, these two pieces of information are
all that is necessary. There are several options for adding minutes to the account: you
can purchase Prepaid Wireless Phone cards at retail stores, from some ATM machines

performing with no problems.

TM

features an internal, resettable fuse which never requires service. If

CellStatTM uses prepaid cellular service

26

MICROTEL CellStatTM

(e.g. US Bank), or from the carrier’s web site. You will need to know the phone number
and the carrier that is printed on the label.

In addition to minutes being depleted from your dialer’s prepaid cellular account due to
the dialer’s usage of the cellular account, minutes also expire after fixed time periods.
The dialer is commissioned with $100 of prepaid cellular minutes at the factory; this
initial account expires after one year. Therefore, check the expiration date by calling
either the toll-free Cingular or T-Mobile service center numbers (depending upon which
carrier is printed on the label shown in Figure 3), given here:

Cingular GoPhone Pay As You Go Service Number: 1-800-901-9878

T-Mobile To Go Customer Service Line: 1-877-778-2106

Again, in both cases you will need to know the cellular phone number of your dialer; this
is printed on the label located near the cellular antenna on the upper left-hand side of the
dialer enclosure (See Figure 3 in the Installation chapter).

When you refill your account, you will be told the new expiration date. Keep track of
this. The dialer only keeps track of the dollar balance, not the expiration date. The
reason is that the expiration dates vary depending upon the carrier, the number of minutes
already purchased, and often promotions. With Cingular, if you add more minutes before
your current expiration date, your remaining minutes/account balance will roll over to the
new expiration date.

Spoken Fault/Error Messages

During an alarm callout or when checking the system status the dialer may annunciate
error messages other than those recorded for the four input channels. The following is a
description of their meanings and actions to take:

Dialer Spoken Message
“Data Error” Review all dialer configuration data and telephone
numbers. Re-entering at least one

“Cellular Status Error” The internal cellular modem may not have initialized
correctly upon power on. Power cycle the dialer, then
check status with the *00 command. If the fault persists
there may be a faulty cable connection to the cellular
modem. Call Microtel Technical Support: 1-225-303-0436

“Cellular Balance Fault” The cellular prepaid balance is below $5. See the
instructions above to refill the account.

telephone number).

Cause: Phone number not entered correctly.
Cause: Call being placed to different number than expected.
Cause: Phone line not plugged-in, phone line broken or in use.
Cause No touch-tone service, use pulse dial by pre-pending *1 to each phone number.

Symptom: Unable to program with local telephone.
Cause: External 12 VDC power required. (Green AC power/charging LED must be on)

Cause: Incorrect command format (all commands begin with * or **). To clear out the

message buffer at any time, press the ‘#’ key.

Cause: Touch-tone phone must be used (listen for tones when keys are pressed).
Cause: Phone not plugged in correctly (local telephone must be plugged into PHONE

jack, and OFF HOOK LED should be on).
Cause: Dialer off-hook placing call (RING/ACTIVE LED is on).
Cause: Very loud or noisy environment -- program from remote phone or use a mute

button on the local phone.

Symptom: Not placing alarm call (RING/ACTIVE LED does not come on).

Cause: Fault input not really in alarm or is not a new alarm. FAULT LED should blink.
Cause: Alarm delay is too long. Try setting a shorter Fault Delay period.
Cause: Local telephone is off-hook. Is OFF HOOK LED ON? This Halts the dialer.
Cause: Intercall (Snooze or Call-spacing) delay set. Dialer waits before next call.
Cause: No telephone numbers to call. Review telephone numbers.

Symptom: Dialer is dead (AC POWER LED is off).

Cause: Check power to dialer. Make sure it is wired properly.
Cause: No external power and internal battery is dead.

Symptom: Dialer is dead (AC POWER/CHARGING LED is ON, Power switch is ON)

Cause: Review all System and Fault Input configuration, and Telephone Numbers.

Nonvolatile data may have been corrupted, not entered, or incorrectly entered.
Enter *00- The dialer will recite the status of the dialer then “Data Error” if

there are any corrupted nonvolatile parameters. Reconfigure if this is the case.

Symptom: Not placing cellular alarm call(s).

Cause: Telephone number does not have a *70 at the beginning to indicate the dialer

should call out via the cellular connection. Review telephone number(s).
Cause: Cellular prepaid balance is too low. Check remaining balance by querying

dialer with *00 command. Follow instructions earlier in this manual to refill

Command **68 *1 5551212 **

Response: Telephone number eight is STAR one five five five one two one two

z Reduced power operation CellStatTM’s already low power consumption can be

reduced 33% for installations providing minimal power, such as solar panels. To
enable reduced power mode enter the following command:

**054 Toggle normal/low power mode

Example- Command: **054

Response: Low power enabled.

Example- Command: **054

Response: Normal power enabled.

Each time the command is entered, the power mode toggles between normal / low power
mode. Visually, this is indicated by a reduced duty cycle of the four (4) ALARM
STATUS LEDs: in low-power mode, the LEDs flash very briefly once a second; in
normal mode the LEDs are mostly ON, but briefly flicker OFF once a second.

In addition to configuring the dialer to operate in low-power mode with this command,
power consumption can be reduced even more by de-energizing an unused local alarm
output.

Example- Command: **061

Response: The local output is open.

This will reduce current consumption of the dialar by an additional 10 milliamps. Use
this additional option if the local relay output is not being used as a summary alarm
output or to control external equipment.

z Using non-prepaid cellular plans CellStatTM normally uses prepaid cellular service

from either Cingular or T-Mobile, and is usually ordered from Microtel already
commissioned with a prepaid SIM from one of those carriers. This offers the lowest
operating cost for users, since charges are incurred only when the dialer consumes
minutes or sends/receives SMS text messages. However, if you wish to use the dialer
with a regular post-paid, monthly plan, the prepaid algorithm can be turned OFF
using the following touch-tone command:

32

MICROTEL CellStatTM

**055 Toggle cellular prepaid plan

Example- Command: **055

Response: Cellular balance status is disabled and cellular channel is

zero.

Effect: Turns OFF the cellular prepaid algorithm and selects
AT&T/Cingular (cellular channel zero) as the carrier.

Example- Command: **055

Response: Cellular balance status is disabled and cellular channel is

one.

Effect: Turns OFF the cellular prepaid algorithm and selects
T-Mobile (cellular channel one) as the carrier.

Example- Command: **055

Response: Cellular balance status is enabled.

Effect: Turns ON the cellular prepaid algorithm. Carrier selection
is automatically determined by CellStat’s prepaid account
maintenance algorithm.

As illustrated in the examples above, each time the command is entered the cellular
prepaid plan toggles between being enabled/disabled and/or the post-paid cellular carrier.

NOTE: When turning OFF the prepaid algorithm, the cellular carrier must be manually
configured (Cellular channel ZERO = AT&T/Cingular; Cellular channel ONE =
T-Mobile). This ensures that messages are routed to the correct cellular carrier.
