4.6 Programming
Socket
The 9 pin or 15 pin programming socket on the termination card provides the communication
interface between the detector and a PC or LCD Programmer. Use the information listed below
to determine the type of programming device required to program the VN or the RO detector.
RO
model
The programming socket on the termination card has 9 pins.
Use a PC and connect the RS232 data cable directly to the 9 pin VESDAlink
programming socket.
VN
model
The programming socket on the termination card has 15 pins.
Use a LCD Programmer and connect the programmer cable to the 15 pin
VESDAnet programming socket.
OR
Use a PC with a VESDA PC-Link HLI device and the appropriate data cables
to connect to the 15 pin VESDAnet programming socket.
4.7 Auxiliary
Terminals
There are three pairs of auxiliary terminals on both models designated as:-
a) Bias
b) Reset
c) LED
4.7.1 Bias Terminals
The
Bias (+)
output terminal provides a 10V supply via a 1K resistor to power the Reset
terminals via a Reset/Isolate switch located in another part of the building. The
Bias (–)
terminal
is the Bias ground. Refer to Figure 13 for a suggested circuit.
