SYSTEM COMMUNICATIONS

- A. DIGITAL COMMUNICATOR OPERATION -

4171XT=XM/4171XM

The 4171 XT-XM Dialer Board is required for polling loop andlor wireless zone

expansion, and for office initiated downloading, and is also used to

communicate with the central station via dial network telephone line, if that

service is desired. The 4171 XM can be used if only central station

communication and site initiated downloading is desired. The 4171 XM does

not support system zone expansion or office initiated downloading.

When there is a report to be transmitted, the communicator first seizes the

line to prevent it from being blocked by outgoing calls or-by a phone left off

hook. A short hang-up is executed to insure that any outgoing calls are

disconnected. The communicator then goes off hook and begins to wait for

the PABX dial tone (if a PABX number is programmed) or the external

telephone company dial tone. The communicator waits up to 4 seconds for

the PABX dial tone or up to 5.11 or 30 seconds (whichever is programmed in

field ‘42) for the external dial tone.

If dial tone detect is disabled in field ‘43, the communicator will dial after the

programmed wait time in field ‘42 (5,11, or 30 sets.). lf detection is enabled,

the communicator will dial when it hears dial tone. But if dial tone is not heard,

:t will Qal after the programmed wait time (‘42).

CAUTION: 1. If the wmmunicator is connected to a telephone line inside a

PABX, be sure the PABX has a back-up power supply that can support the

PABX for 24 hours. Many PABXs are nor power backed up and connection to

such a PAEX will result in a communication failure lf power is lost.

2. Refer to phone line hook-up for proper line seizure connections.

NOTE:The system can be programmed to delay alarm reporting for 16

seconds (field “88), which can help avoid transmission of user-caused false

alarms by providing 16 seconds to disarm the system. If the alarm condition

remains after 16 seconds, the report will be sent.

TWO PHONE NUMBERS

Two different telephone numbers (primary and secondary: fields “33 8 ‘34)

can be programmed. Note that if a secondary phone number is used, a

secondary subscriber ID number must be assigned (see fields ‘32 8 ‘90).

The telephone number dialed depends on the report to be sent and on the

report routing option (dual, split or back-up reporting) that is enabled. If dual

reporting is enabled (field ‘51). all reports are transmitted to both numbers. If

split reporting is enabled (field 1’31). each report is transmitted to its

assigned number. Back-up reporting is also available, and is automatically

enabled tf a secondary phone number is programmed. Backup reporting

sends reports to the secondary number only if attempts to get through

to the primary number are unsuccessful.

After dialing the telephone number, the communicator will wait up to 30 or 60

seconds, whichever is programmed (field ‘45 8 ‘47), for the receiver’s

acknowledgment tone (handshake). The communicator will begin

transmitting its reports when the acknowledgment tone is received. If the

acknowledgment tone is not detected during the programmed waiting

period, then the communicator will hang-up and pause for 30 seconds,

insuring that any incoming calls are disconnected before attempting to dial

again (Vu&Jam”). The communicator will make 8 attempts to transmft a report

to one or both telephone numbers, depending upon the report routing

Option

programmed. After the eighth attempt, the communicator will hang-up

and a Comm Failure (513OXMS137) or FC message (4130XM14137) will be

displayea at the Console.
