Input Activation Conditions
Control Inputs 1 & 2
To activate an input it must be connected to an external circuit that returns to either of the two ground ( )
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 ground
( ) 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.
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.
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.
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.
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.
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 programmed for the emergency.
General Purpose Inputs
These connections provide functionality of the option inputs on the LSI-16e or of the LSI-16 that has been
upgraded with an Interface Module (IM-16). On an LSI-16 without an option board, these connections will
remain inactive.
Two connectors, labeled Option A and Option B, are located on the back of the LSI-16e. Each slot
consists of 14 pins which are labeled 1 to 14. Each connector bank allows for the following connection:

Chassis Ground: One connection per connector bank.

Isolated Ground: Four connections per connector bank.

Control Inputs: Eight connections per connector bank.
