LSI-16 REAR PANEL
Monitored Outputs
Two black ve-position connectors are located next to the rotary switches. These are predominantly used for Monitored Outputs to external
lamps or sounders. Individual connections are labeled 1 through 8 as indicated below. One connection is congured for use as both an
input and an output (1) and one as an input (2) (see table below for connector assignments).
The outputs will sink current (pull low) when active (see the Specications section of this document for more details). The desired load
(lamp, LED, etc.) must be connected between the output terminal and a positive voltage reference.
It should be noted that external switches and a sounder connected to the rst two inputs are typically mandatory for standards compliance.
The location and physical attributes of these items may be required to conform with local norms. The switches and sounder must be wired
according to the connection diagram provided below.
Sounder Output / Silence Input
This connection functions as a dual purpose alarm sounder output and silence input (see connection diagram below).
Sounder Output
This output connects to a local sounder for fault and alarm warnings. A sounder is typically required for standards compliance.
Note: If an emergency microphone is located near the sounder, it may be congured in Vocia software to mute the sounder while
making live announcements.
Silence Input
This input is used to silence the local sounder. The sounder will restart in response to any new fault or alarm.
System Fault Reset Input
This input is required to take the LSI-16 out of System Fault condition. Note: the LSI-16 will always power up in a system fault state (see
connection diagram).
