Control Inputs
Two five-position plug-in barrier strip connectors provide control input connections. Eight separate channels plus two ground pins are
provided (see table below for connector assignments). Control inputs are fully isolated from all connections in the LSI-16/LSI-16e.

Input Activation Conditions
Control Inputs 1 and 2
To activate an input, it must be connected to an external circuit that returns to either of the two pins. The resistance of this circuit must
be less than 4kΩ.
Control Inputs 3 to 8
These inputs must be permanently connected to an external circuit that returns to either of the two pins. The resistance of this circuit
must be between 1kΩ and 4kΩ. To activate an input, pull the input to a voltage between 12 and 24V.
(Input 1) PSU Fault
This input may be derived from the primary 24V power supply to indicate to the LSI-16/LSI-16e if there is a fault in the power supply. This
may be required for standards compliance.
(Input 2) Ethernet Fault
This input can be derived from an Ethernet switch to monitor the Ethernet network connection between the LSI-16/LSI-16e and amplifier.
This may be required for standards compliance.
(Input 3) Voice Alarm Silence from CIE (fire alarm system)
This input is a signal from the CIE (fire alarm system) that will mute emergency messages in all emergency zones.
(Input 4) Voice Alarm Reset from CIE (fire alarm system)
This input is a signal from the CIE (fire alarm system) that will reset emergency messages in all emergency zones.
(Inputs 5-8) Emergency Inputs
These four inputs are used to connect to the fire alarm control and indicating equipment (CIE) and notify the LSI-16/LSI-16e that an
alarm has occurred on a particular zone. Four such zone inputs may be connected; one emergency message or mute can be assigned per
zone. Additional zone inputs are available with the IM-16. When an alarm is detected, the Vocia system will enter Emergency Mode as
configured for that input. During Emergency Mode, some or all of the Vocia system will cease normal operation and operate as pro-
grammed for the emergency.
