SP40S Multi-Function Communications System 59
WARNING: MESSAGES REQUESTED BEFORE AND DURING A TROUBLE
CONDITION MAY NOT BE HEARD, WHICH COULD RESULT IN SERIOUS
INJURY OR DEATH TO YOU AND/OR OTHERS. IF MESSAGES REQUESTED
BEFORE AND DURING A TROUBLE CONDITION ARE STILL NECESSARY,
REPEAT THEM WHEN THE SP40S PANEL IS RETURNED TO NORMAL.
5.3.1 Visual Notification Appliance Output Circuit Supervision
The Visual Notification Appliance Output Circuit uses Class B, Style Y wiring, and is
supervised for open and short circuits when the output is de-energized. Output circuit
supervision requires installation of UL Listed 10K Ohm, ½ W EOLR on the output circuit.
A sensed strobe short circuit trouble illuminates D96 STB SHORT LED. A sensed strobe
open circuit trouble illuminates D97 STB OPEN LED. See Figure 8-1 for LED location.
5.3.2 Audio Notification Appliance Output Circuit Supervision
The Audio Notification Appliance Output Circuit uses Class B, Style Y wiring, and is
supervised for open and short circuits when the output is de-energized. Output circuit
supervision requires installation of UL Listed 10K Ohm, ½ W EOLR on the output circuit.
A sensed open circuit trouble illuminates D1 AUDIO OPEN LED. A sensed strobe short
circuit trouble illuminates D2 AUDIO SHORT LED. See Figure 26 for LED location.
5.3.3 Amplifier Supervision
An inaudible supervisory tone plays through the Amplifier section during standby for
supervision purpose. Any sensed trouble illuminates D5 “AMP” LED steadily. See Figure 8-
1 for LED location.
5.3.4 Ground Fault Supervision
The SP40S Multi-Function Facility Communication System supervises for Ground Fault
conditions on Class B, Style Y field wiring that is not electrically isolated. The supervised
wiring includes contact inputs, visual NAC circuits, audio NAC circuits, amplified speaker
NAC circuits, and trouble audible output circuits. All other wiring is electrically isolated. If
a Ground Fault condition exists, D67 GF LED illuminates. See Figure 26 for LED locations.
