5. OPERATION
This chapter gives a detailed description of exactly how the B1290 will operate after the start-up programming has
been completed. Parameters which may be altered are pointed out, with reference to the appropriate Program Code
section.
Alarm Sequence
When the B1290 receives an alarm on one of its inputs, it goes off hook and listens for dial tone. If dial tone is not
present, the B1290 will hang up and try again. After three unsuccessful attempts to detect dial tone, the B1290 will
conclude there is a problem with the line and stop dialing. When this occurs the unit will report
Telephone Access
Error over the radio, set the error relay and flash the RUN and HOOK LEDs.
If dial tone is detected, the B1290 dials the first telephone number stored in Directory A using tone dialing. When
the telephone line is answered, the B1290 will announce its Site ID, the list of any alarms present, and prompt the
user to
Enter Acknowledge Code . It will repeat this message a minimum of three times, pausing five seconds after
each announcement to wait for an acknowledgment. When the Acknowledge Code is detected, the B1290 will
announce
Alarms Acknowledged and then prompt “Enter Control Code”.
If the line is busy, if there is no answer, or if the B1290 does not receive the Acknowledge Code after announcing
the alarm, it will hang up the telephone line, then go off hook again and dial the next number in the directory. If the
B1290 dials all the way through the directory without being acknowledged, it will wait two minutes (Interval Timer
A), then start dialing again from the top of the directory. After three tries (Times A) at two minute intervals, the
B1290 will retry the list every ten minutes (Interval Timer B) thereafter, not stopping until it is acknowledged.
All of the timers and intervals mentioned above are adjustable. In addition, the B1290 may be programmed to
announce the alarm a number of times over radio, or a public address system, as well as dialing on the telephone.
Acknowledging an Alarm
When the B1290 calls you on the telephone, it may take up to five seconds before it starts speaking. After it
announces the alarms, it prompts you to
Enter Acknowledge Code. You have five seconds to begin entering the
digits.
If the B1290 has been programmed to operate its relays (Program Code 3, DTMF Codes), you may send a relay
code over the telephone before acknowledging the alarms. The B1290 will actuate the relay, speak the associated
voice message, and then prompt you again to
Enter Acknowledge Code.
After the B1290 has detected the Acknowledge Code, it will speak the phrase Alarms Acknowledged and return to
the “Enter Control Code” prompt. If no activity occurs for 5 seconds it will hang up.
Appending the # digit at the end of the Acknowledge code allows you to acknowledge the alarm for sixty minutes
only. After one hour, the B1290 will check the alarm inputs again, and if the same alarm is still present, it will begin
the reporting cycle just as if it was a new alarm.
Any series of digits entered immediately after the acknowledge code will be echoed back to the user. This feature is
sometimes used in systems applications.
To acknowledge the B1290 locally, activate the local acknowledge switch connected to the unit (see the section on
“Installation - Local Acknowledge”). The alarms may be acknowledged at any time. The
Alarms Acknowledged
announcement will occur whenever the B1290 is available to speak.
Telephoning the B1290
When you call the B1290 on the telephone, it will answer after four rings (Rings before Answer) and announce its
site ID, any alarms which are present, and the status of any relays which have been assigned codes. After this
announcement, the B1290 will prompt you to
Enter Control Code . The B1290 then waits ten seconds for you to
enter a code. This could be a code to operate one of the relays, an Acknowledge Code, an Interrogate Code, or an
Access Code which would allow you to go into the programming mode. If an Access Code (password) has not been
programmed, the B1290 will automatically go into the programming mode after five seconds, prompting you to
