WARNING: MESSAGES REQUESTED BEFORE AND DURING A TROUBLE CONDITION MAY
NOT BE HEARD, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS
INJURY OR DEATH TO YOU AND/OR OTHERS. IF MESSAGES REQUESTED
BEFORE AND DURING A TROUBLE CONDITION ARE STILL NECESSARY, THEY
SHOULD BE REPEATED WHEN THE SAFEPATH
®
PANEL IS RETURNED TO
NORMAL.
Visual Notification Appliance Output Circuit Supervision
The visual notification appliance output circuit is supervised for open and short circuits when the output is
de-energized. Output circuit supervision requires installation of the supplied UL LISTED, 10K Ohm EOLR
on the output circuit. Any sensed trouble will illuminate the “STR” LED on the amplifier module. See
Figure 7-1 on Page 7-2 for LED location.
Audio Notification Appliance Output Circuit Supervision
The audio notification appliance output circuit is supervised for open and short circuits when the output is
de-energized. The circuit is unsupervised when the output is energized. Output circuit supervision
requires installation of the supplied UL LISTED, 10K Ohm EOLR on the output circuit. Any sensed
trouble will illuminate the “SPK” LED on the amplifier module. See Figure 7-1 on Page 7-2 for LED
location.
Amplified Speaker Notification Appliance Power Output Circuit Supervision
The amplified speaker notification appliance power output circuit supervised for open and short circuits
when the output is de-energized. Output circuit supervision requires installation of the supplied UL
LISTED, 10K Ohm EOLR on the output circuit. Any sensed trouble will illuminate the “PWR” LED on the
SALL-15S module. See Figure 7-1 on Page 7-2 for LED location.
Amplifier Supervision
A supervisory tone plays through the amplifier during standby for supervision purpose. Any sensed
trouble illuminates the “AMP” LED on the amplifier module. See Figure 7-1 on Page 7-2 for LED location.
Ground Fault Supervision
The SAFEPATH
®
Panel supervises for ground fault conditions on field wiring that is not electrically
isolated. The supervised wiring includes contact inputs, visual NAC circuits, audio NAC circuits, amplified
speaker NAC circuits, trouble audible output circuits, remote microphone station wiring and MDX-2 wiring.
All other wiring is electrically isolated. Ground fault supervision may be enabled and disabled by switching
the ground fault enable switch on (GND FLT ENB, SW4, POS 1). See Figure 3-18 on Page 3-17.
Remote Microphone Supervision (Optional RMS-2)
The audio circuit is supervised on the Remote Microphone Station PCB.
Section 4-4 - Actions That Initiate Alarms
Table 4-1 indicates what can initiate an alarm condition and the resulting SAFEPATH
Panel actions.
NOTE: The list is arranged in order of priority (e.g., number 1 in Table 4-1 supersedes number 2
priority).
