10
This timer sets the maximum amount of time the
K-1270
will look for the call to be answered. If this timer expires
and the tenant has not answered, the call will be terminated or the
K-1270
will dial a second phone number (if
programmed). The factory setting is 20 seconds, and to disable this feature, enter “
00
” into position 43.
J. Maximum Ring Time
This time out is started once the call has been connected and is reset every time audio is detected on the phone
line. If it expires, the call will be terminated. This is useful on systems that are silent when the tenant hangs up to
assure the
K-1270
disconnects. It is factory set to 10 seconds and can be disabled by entering “
00
” in position
44.
K. Silence Time Out
This time represents the amount of time the
K-1270
will delay before switching back to the microphone mode
after it was in the speaker mode (VOX switching time). It is in 100 msec increments and stored in position 45.
L. Talk/Listen Delay
On some phone lines, a faster rate of dialing is allowed. The dialing speed of the
K-1270
can be altered to take
advantage of this faster rate. The normal dialing speed is 5 digits per second and is selected by entering “
#30
”
(factory setting) while in programming. To increase the speed to 10 digits per second, enter “
#31
”. If the faster
rate is selected, be sure to test each number to assure proper operation.
M. Dialing Speed
The
K-1270
is factory set to hang up if continuous audio is detected after dialing. In most situations this would
happen if the tenant hung up and the service that the
K-1270
is connected to provides a dial tone following the
hang up. In some instances due to noisy lines or loud background noise, the call may be terminated before the
tenant hangs up. If this occurs, enter “
#33
” when in programming. This will disable return to dial tone feature and
stop the
K-1270
from hanging up prematurely. To enable this feature enter “
#32
” when in programming.
N. Hang Up on Return to Dial Tone
See Operation for a functional description of this feature. Tenant Initiated Entry is disabled by default. To enable
it, enter programming (see
Programming
section
A
). Enter
#38
. Also, DIP switch 1 must be turned ON and left
in this position to enable the
K-1270
to answer incoming calls. To disable Tenant Initiated Entry, enter
#37
.
Security considerations with Tenant Initiated Entry:
The
K-1270
door entry system is designed with security
in mind, which is the reason an access code is recommended in cases where Tenant Initiated Entry is allowed.
To understand the need for an access code, consider the following example. A person walks up to the entry and
pushes one of the directory buttons on the
K-1270
. The unit looks up the number associated with that directory
position and dials it. The phone inside the tenant’s apartment rings, and is answered by someone who happens
to be a guest in the tenant’s apartment. The guest notices that the tenant’s phone is displaying the caller ID of
the number that just called, which is the number of the
K-1270
. They jot the number down. The guest can now
call the
K-1270
at a later time, if DIP switch 1 is on, Tenant Initiated Entry is allowed, the access code is disabled,
and they know the door strike code, they can let themselves into the building. Note that by default, Tenant Initiated
Entry is not allowed, but if this feature is allowed, it is important to program an access code (see
C. Access Code
(
memory location #48
).
O. Tenant Initiated Entry
To clear all speed dial positions and set all modes back to factory setting, enter “
###
“ while in programming.
Caution
, all previous programming will be lost
. Normally when the
K-1270
is in the programming mode, it will
hang up the line if no commands are detected for 20 seconds. To hang up immediately, enter “
##7
”.
P. Special Commands
In some installations, it maybe desirable to limit the length of the call to the tenant. This can be done by
programming position
#42
. The maximum call time can be set from 1 minute to 9 minutes by entering the
appropriate number in position
#42
. A “
0
” will yield a 30 second time. To disable the call timer enter “
#42
” without
any preceding digit.
