I. Automating the Call Connected LED
There are two methods of turning on the Call Connected LED. The LED will turn on after a Touch Tone , is detected
from the distant party or after the voice announcer is finished playing a programmed number of times. If you want the
Call Connected LED to light automatically when the call has been answered, but you don't want a voice announcement
to be played, follow these programming steps:
Step 1:
Access Programming as shown in section A
J. DIP Switch Programming/Speaker and Microphone Adjustments
Two POTs are provided to increase or decrease speaker volume and microphone sensitivity. In certain noisy locations the micro-
phone sensitivity may need to be decreased as shown below.

K. Central Station Programming
The standard 1600A emergency 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.
1. Central Station Programming Features
a. Accessing the Programming Mode
Before programming, you must access the programming mode (see Programming section A).
b. Enabling/Disabling Central Station Mode
The 1600A Series emergency phone can be placed in the "Central Station Mode" by entering a central station phone num-
ber in position #05 while programming. To cancel the "Central Station Mode," clear position #05 by entering #05 only (see
Programming section D).

...to disable central station programming
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 min-
imum 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).
