Overview of Onboard Outputs
The C900TTL-X has 4 open-collector outputs onboard:
•
Output 1:
Active (shorted to ground) as long as the CPU is functioning
normally. If the CPU fails to operate or the CPU loses power, output 1 will be
open.
•
Output 2:
Active as long as the D6600 Receiver is communicating properly,
and open when the D6600 is not communicating to the C900TTL-E.
•
Output 3:
Active whenever the C900TTL-X is in Intercept Mode.
•
Output 4:
Controlled by command from the D6200 software (default is open).

Overview of Onboard Terminal Strip
The following list describes the functions of the C900TTL’s Power Terminal Strip:
•
+12 V:
Connect regulated 12 volt DC power to this terminal and the -12 V
terminal. This power may be supplied by a separate power supply, battery, or
Auxiliary power from the Control/ Communicator.
•
-12 V:
Return terminal for the 12 VDC power supply
(earth ground
connection)

Setting the Dipswitches
A 10-position dipswitch programs the C900TTL.
The programming is dependent on the application
and dialer format of the Alarm Panel that it is to be
connected to.

Switch positions 1,2,3, & 4 all work together to program the dialer format into the C900TTL.
The C900 must emulate a phone line and a digital receiver. It must therefore be programmed to
know what format it will be receiving from the alarm panel.
