b. Enabling/Disabling Central Station Mode
The
1600A
Series assistance phone can be placed in the “Central Station Mode” by entering a central station
phone number in position
#05
while programming. To cancel the “Central Station Mode,” clear position
#05
by
entering
#05
only (see
Programming
section
D
).
c. Ring No Answer
When the
1600A
Series emergency phone is in the “Central Station Mode”, it is best to have the ring no answer
set to a minimum of three, because some receivers send a long tone after answering the line that sounds like
a ring back. If the
1600A
is set to a ring no answer of two, the phone will disconnect (see
Programming
section
F
).
a. Accessing the Programming Mode
Before programming, you must access the programming mode (see
Programming
section
A
).
The standard
1600A
assistance phone is capable of communicating using the “Ademco Contact I.D.”, “Ademco High
Speed”, “DTMF 4+1 Express”, or the “DTMF 4+2 Express” formats. All formats use the programming memory location
#20
to store the account code and alarm details.
A speaker volume POT is provided to increase or decrease the speakerphone volume.
Note:
The Microphone Sensitivity POT has
been removed because the microphone sensitivity is now microprocessor controlled. This allows the mic gain to be automatically
increased in a quiet environment, allowing the distant party to clearly hear even soft or distant sounds. The microprocessor will
automatically reduce the mic sensitivity when the location becomes noisy. This Automatic Noise Canceling (ANC) feature will allow
speakerphone two-way communications to work properly, even when subjected to loud noise such as a diesel engine or traffic.
