phrase Alarms Acknowledged and return to the “Enter Control Code” level.
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 appli-
cations.
To acknowledge the B1290 locally, activate the local acknowledge switch
connected to the unit (see the section on “Installation - Local Acknowl-
edge”). The alarms may be acknowledged at any time. The Alarms Ac-
knowledged 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 pres-
ent, 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 oper-
ate one of the relays, an Acknowledge Code, an Interrogate Code, or an Ac-
cess Code which would allow you to go into the programming mode. If an
Access Code (password) has not been programmed, the B1290 will auto-
matically go into the programming mode after five seconds, prompting
you to Enter Program Code. You may then program the B1290 from your
telephone, the same as you would from a local programming phone.
The B1290 will hang up whenever it has waited for more than ten seconds
without receiving a DTMF code.
Changing Telephone Directories
Telephone directories can be changed remotely without entering the pro-
gramming mode. The directory can be changed by entering the Directory
Control Code over the telephone system, local programming telephone, or
two-way radio.
Refer to the Directory section, Program Code 2, for a description of the di-
rectory format and its uses.
This example uses the local programming phone to change the telephone
format from DIRECTORY A to DIRECTORY B and then to DIRECTORY C.
A typical installation may use a programming telephone mounted perma-
nently at the site to make this procedure as simple as possible.
