Matrix User Guide.
Status Output Pins
The status output pins (7, 16, 20 and 22) signal based upon the NEMA TS-2 standard. In a TS-2 cabinet, the
detector rack BIU is meant to detect these signals, and send message frames over SDLC to the controller,
indicating which state the status pins are in.
The three potential status states of those pins are as follows:
■
Normal operation –
continuous low or on state
■
All channels currently in reset –
continuous high or off state
■
Detector unit in failsafe mode –
pulse width modulation with 50 milliseconds on time and 50 milliseconds off time
