High level sounder for Fault/Alarm warning•
Dual power summing with power loss fault connection•
Provides terminating resistors for Alarm and Fault Inputs•
Provides terminating resistors for any unused monitored outputs•
Current limited reference voltage output•
Rack mountable (1RU)•
CE marked and RoHS compliant•
Covered by Biamp Systems’ warranty•
Setup and Use
A CI-1 requires an LSI-16 for operation. While the LSI-16 requires conguration in Vocia software, a CI-1 requires only an interconnection
with an LSI-16 as detailed below. Once the required interconnections have been established, the CI-1 will operate with the LSI-16 to
provide the necessary functionality. It is recommended that the CI-1 be mounted immediately adjacent to an LSI-16 so the CI-1 controls
can be associated with indications on the LSI-16.
Vocia installations designed to comply with the requirements of EN 54-16 must be installed in accordance with Biamp recommendations
detailed in this User Manual and in the Vocia VACIE Reference Guide (download from www.biamp.com).

FRONT PANEL
The CI-1 has three switches on the front panel and an internal (local) sounder, audible through the panel.
Local Sounder
The local sounder commences whenever any alarm input receives an external signal from the re detection equipment, control and
indicating equipment (CIE) or equivalent. It will also commence when any fault is detected. The sounder will continue until the alarm
or fault is reset.
Local Sounder Silence Switch
If the local sounder is operating, this switch may be used to silence it. The alarm or fault condition that caused the sounder to operate is
unaffected by operating this switch. If a new alarm or fault is detected, the sounder will restart. Press and hold the switch for two seconds
to operate.
System Test Switch
This switch will initiate a test sequence on the LSI-16. All indicators in use on the LSI-16 will light briey and the sounder in the CI-1 will
sound briey, thus conrming that essential annunciators are functional. Press and hold the switch for two seconds to initiate the test
sequence.
System Fault Reset Switch
A System Fault denotes that the LSI-16 cannot guarantee correct operation of the Vocia system in an emergency mode. It is indicated on
the LSI-16 and by the sounder in the CI-1. A system fault can only be cleared by operating the System Fault Reset switch. Note that when
the LSI-16 is powered up, the System Fault will be operational until the System Fault Reset switch is pressed. Press and hold the switch
for two seconds to reset a System Fault.

REAR PANEL
There are four main interconnection paths to the rear panel:
Connections to the re detection system (CIE);•
Connections from external devices for fault indications•
Connections to the LSI-16•
Power supply connections•
Each of these connection paths has several circuits as detailed below.
Fire Detection System (CIE) Connections
These circuits are provided on two ve-position plug-in barrier strip connectors. The
Isolated Ground provides a circuit return that is not directly connected to the CI-1
and LSI-16 Ground.
Alarm Inputs 1 through 4 are signals from the re detection system. These signals
place the Vocia system into emergency mode according to the conguration
determined for the input in Vocia software. The Alarm Reset Input cancels all active
alarms in the system while the Alarm Silence Input maintains all active alarms but
causes emergency messages to be silenced. The CI-1 provides the necessary
terminating resistors for each input. Inputs are asserted by a positive transition
to 12-24V with respect to the ‘Isolated Ground’ connection. This transition should
preferably be derived from a dry contact closure to a remote 12V-24V source, or
to the CI-1 24V Reference Out (see below).
The Voice Alarm Active output is provided to signal to the re detection system that
the Vocia system has been activated in emergency mode in response to an Alarm
Input. A constant output denotes that an emergency message is playing. A pulsed
output (1.25Hz) indicates that an alarm is active but emergency messages have
been silenced.

Function

Ground
The General Fault Output is provided to signal to the re detection system that there
is a fault in the Vocia system that could affect delivery of an emergency message.
The Voice Alarm Active and General Fault outputs pull low (to ground) when active.
The outputs are monitored by the LSI-16 for open-circuit or short-circuit to ground or
power supply and for over-voltage on the output pin (>35V DC). If incorrect conditions are detected a Fault is signaled. Output monitoring
facilitates compliance with voice evacuation standards. For monitoring purposes a load (maximum 22kΩ) must be connected between
each output and a positive voltage source referenced to the LSI-16 Ground, at the far end of the connection to the CIE (i.e. at the CIE).
An LED indicator connected through a resistor to a positive voltage at the CIE will sufce as a monitoring load.
Note that the LSI-16 provides a 10V source at the ‘10V Out’ terminal on the LSI-16. Outputs may be pulled up to this source; however the
total current drawn from the source must not exceed 100mA. If an external voltage source is used for the outputs, it must not exceed 35V
DC and in addition to the output loads, must also be connected to the LSI-16 ‘External Supply Over-voltage Monitor’ input (refer to LSI-16
User Manual) for monitoring purposes. Due to monitoring constraints, it is not possible to use both the LSI-16 internal 10V source and an
external source.

Connections from External Devices for Fault Indications
These circuits are provided on a single ve-position plug-in barrier strip connector. All
Inputs are fully isolated from the CI-1 and LSI-16 internal circuits. The Isolated Ground
provides a circuit return that is not directly connected to the CI-1 and LSI-16 Ground.
These inputs allow the signaling of faults from external devices to the Vocia system
so it may indicate and log faults that could affect emergency operation. These fault
signals are typically derived from contact closures on external devices. For multiple
devices (e.g. Multiple UPS units), fault contacts from each device may be ‘wired-OR’
connected (connected in parallel) to the fault input. UPS fault inputs are typically
derived from UPS units used in the system (e.g. for backup powering of VA-8600
units). PSU fault inputs are typically derived from battery-backed power supplies
used to power parts of a Vocia system. EWS PSU fault inputs are derived from
optional emergency microphones (EWS-x) to indicate loss of power supply. Ethernet
fault inputs are derived from fault contacts of industrial Ethernet switches used in
critical parts of a Vocia system.
All fault inputs are asserted by connecting the relevant pin to Isolated Ground. The UPS Fault, PSU Fault and EWS PSU Faults must be
connected to 24V when non-asserted either by direct connection or through pull-up resistor (maximum 2.2kΩ). The 24V reference voltage
output on the power supply connector may be used for this purpose. The Ethernet Fault input is pulled-up internally and does not need an
external pull-up.

Connections to LSI-16
These circuits are provided on four (4) ve-position and one (1) three-position plug-in barrier strip connectors plus a DC barrel jack.
Each connector label is prexed by “To LSI-16…” Connectors are located so that with the CI-1 mounted directly above or below the LSI-16,
circuit connections may be made by directly connecting pin-for-pin to the vertically adjacent connector. Short interlinking cables are
provided with the CI-1 for this purpose. Refer to the LSI-16 Operation Manual for the circuit functions of these connectors.
Note that the LSI-16 PSU Fault, Protection Fault and Path Fault outputs are connected to the CI-1 purely for the purpose of providing
required monitoring resistors (these outputs are not otherwise used by the CI-1). If these outputs are required for remote fault indications,
the relevant connections should be removed from the Monitored Outputs connector of the LSI-16. As described in the LSI-16 Operation
Manual, and external monitoring resistor will be required if these circuits are so used.
Power Supply Connections
These circuits are provided on a single ve-position plug-in barrier strip. Inputs
are provided for two 24V power supply circuits to drive the LSI-16. This facilitates
standards compliance by providing a means of redundant connections.
Each power supply must be capable of 24V DC at 15Watts. The Ground 1 and
Ground 2 connections are internally connected together and to system ground.
The VRef connection may be used as a voltage source for pull-ups on required fault
inputs. This output is current limited at 100mA.
Loss of power to either power supply input will result in the LSI-16 detecting a fault.
If standards compliance is not required for an installation, a single power supply
connection must be paralleled to the two power supply inputs to avoid generating
a fault signal.

INSTALLATION
The CI-1 requires one rack space 1.75 inches (44.45mm) high and 19 inches (483mm) wide with 10 inches (254mm) depth. Mounting
the unit using four screws with washers will prevent marring of the front panel. PVC or nylon washers are appropriate.
Please install the unit away from heat sources, such as vents and radiators, and in rooms with adequate ventilation. Ensure that air can
circulate freely behind, beside, and above the unit. Do not exceed the maximum ambient operating temperature of 32-113 degrees F
(0-45°C).Beware of conditions in an enclosed rack that may cause the temperature to exceed ambient room conditions.
Note: To operate correctly, the CI-1 requires an accompanying LSI-16 plus connections to external components and devices as described
in this manual.The CI-1 should be mounted in close proximity to the accompanying LSI-16.
For EN 54-16 compliance, refer to the Vocia VACIE Reference Guide which details mandatory installation requirements.
