5.4 Miscellaneous Operating Instructions
The talk time for directory codes 0, 00, 000, 0000 and 1, 01, 001, 0001 is
factory set to 4 minutes 15 seconds
and cannot be
changed. These directory codes should be reserved for use with management or emergency phone numbers that typically
require longer talk times. For example, if directory code 000 was programmed to call a management phone number, the system
will allow the
full 4 minutes and 15 seconds of talk time before automatically ending the call.
5.4.1 Talk Time
More than one telephone entry system
can share the same phone line
provided the units have been programmed for
multiple
systems
on the same line (see section 3.2.7). When the unit is programmed for multiple systems sharing the phone same line,
it checks the phone line for 48 volts (not busy) before attempting to place a call. If the phone line is in use, the system will emit
a busy signal. If two or more systems are sharing the same phone line, it is important that each system be programmed with
its
own unique master code
. When more than one system is sharing the same phone line, and a call is placed from one of those
systems to a resident,
ONLY the system that placed the call
will respond to the
tone open
number that will be sent back to the
unit from the resident’s phone. Other units sharing the same phone line
WILL NOT
respond to the tone open number sent from
the resident’s phone.
5.4.2 Telephone Line Sharing
If the telephone entry system is going to be connected to a PBX system, you may need to program extension numbers in place
of a seven-digit telephone number. To do this, enter the extension number and fill the remaining spaces with the “
#
” key in the
phone number programming step. For example, if the PBX system uses four-digit extensions, and you want to program
extension 2217 as a phone number in step 3 of section 3.5.2, press:
2 2 1 7 # # #
*
(
beep
).
If the PBX system requires you to dial 9 to obtain an outside line, and you want to program some, but not all, outside line phone
numbers in the system, program the number “
9
” as
one of the alternate area codes
in step 3 of section 3.5.3:
press:
9 # # #
*
(
beep
).
Then program the outside phone number as a long distance number (section 3.5.4) using the area code reference number that
was used to program the number “
9
”.
5.4.3 Connection to a PBX System
If the telephone entry system is installed in an area where the telephone company has instituted 10-digit dialing, simply
program the required number of alternate area codes into the system without preceding the area code with the number 1.
If
310
was one of the area codes required in step 3 of section 3.5.3 press:
3 1 0 #
*
(
beep
).
Then program the outside phone number as a long distance number (section 3.5.4) using the area code reference number used
to program
310
. Program additional area codes and phone numbers as described in sections 3.5.3 and 3.5.4.
