2) Keep these instructions.

3) Heed all warnings.

4) Follow all instructions.

5) Do not use this product near water.

6) Clean only with dry cloth.

7) Do not block ventilation openings.
Install in accordance with the
manufacturer’s instructions.

8) Do not install near any heat
sources such as radiators, heat
registers, stoves, or other product
(including amplifiers) that produce
heat.

9) Only use attachments/accessories
specified by the manufacturer.

WARNING - To reduce the risk of fire or electric shock, do not expose this product to rain or
moisture.

10) Use only with equipment rack, cart,
stand or table designed to provide adequate
mechanical strength, heat dissipation and
securement to the building structure.

When a cart is used, use
caution when moving the
cart and product combination
to avoid injury from tip-over.

11) Unplug this product during lightning
storms or when unused for long periods of
time.

12) Refer all servicing to qualified service
personnel. Servicing is required when the
product has been damaged in any way, such
as power-supply cord or plug is damaged,
liquid has been spilled or objects have fallen
into the product, the product has been
exposed to rain or moisture, does not
operate normally, or has been dropped.

CAUTION - The Installation steps for ‘Auxiliary Power’ are for use by qualified personnel
only and must comply with all local codes.

 National Electrical Code, ANSI/NFPA 70 for United States.
 Canadian Electrical Code, Part 1, CSA C22.1, Sections 2-128, 12-010(3) and 12-100

for Canada.

Explanation of safety related symbols - Product labeling and the operation manual may
use the internationally recognized symbols defined below to note safety messages.

Lightning Bolt: Hazardous Live voltages present when this unit is in operation. Do
not touch terminals marked with this symbol while the unit is connected to live power.

Exclamation Point: Replace components (i.e. fuses) only with the values specified by
the manufacturer. Failure to do so will compromise safe operation of this unit.

VOCIA GENERAL PURPOSE INPUT OUTPUT DEVICE (GPIO-1)

The GPIO-1 provides sixteen general purpose inputs and sixteen general purpose outputs to control various aspects of a Vocia system.
The GPIO-1 is a monitored device and can be used in life safety applications where more logic inputs or outputs are required. The GPIO-1
has dual powering from PoE Ethernet ports and alternate powering from dual 24V DC inputs. In the event of power loss changeover
between power sources will provide uninterrupted operation.

FEATURES

•  Sixteen general purpose logic input and outputs

•  Device monitoring

•  Able to be used to directly interface with re alarm and emergency equipment

•  PoE capable with alternate powering from auxiliary 24V DC supply (dual inputs)

•  Software-congurable

•  Control over a single Ethernet cable

•  Dual Ethernet ports for redundancy

•  Rotary switches for device identication

•  IP30 Compliant

•  CE marked, UL listed and RoHS compliant

•  Covered by Biamp Systems’ ve year warranty

GPIO-1 SETUP AND USE

Setup and Use

The Vocia software provides the interface for conguring and programming the GPIO-1. The information supplied by this manual relates 

to hardware installation, physical connections and device information. For more details on the software setup please consult the Vocia
Software Help File.

Network

The GPIO-1 is designed to be used in a single Vocia World and utilizes the Vocia CobraNet LAN to communicate.
The unit has two monitored RJ45 Ethernet Network connectors to facilitate redundant connections. The Primary connection will always have
priority over the Secondary connection. Monitoring of the secondary connection can be disabled in the software.

A green power LED is provided and illuminates when PoE power is applied to the unit via either Network port.

Each RJ45 connector uses two LEDs to indicate Ethernet link and network activity (see table below).

Left LED Right LED Description

None None No data connectivity

Yellow Flashing green Network link established. Port is in use

None Flashing green Network Link established. Typically seen on the Secondary port when acting as a failover to the

Primary connection

The maximum distance between any unit and an Ethernet switch is 100 meters (328 feet) when using copper cabling. Additional

Ethernet switches and/or ber-optic cable can be used to further extend distances between devices on a network. 

Device ID

The rotary ID switches are located on the GPIO-1 and give the unit a unique Device ID. The switches
are in hexadecimal format. All GPIO-1 units must have a unique Device ID to function within a Vocia
Paging World (i.e., it is not possible to have two GPIO-1 units with the same Device ID of hex 07). To
assign a Device ID of hex 07, turn the MSB switch to 0 and turn the LSB switch to 7. To create an ID
of hex B7, turn the MSB switch to B and turn the LSB switch to 7. Device ID switches should be set

using a 0.1 inch (2.5mm) to 0.12 inch (3.0mm) at blade screwdriver. More information on setting IDs and the hexadecimal numbering 

scheme used in Vocia can be found in the Vocia Help File.

Please note: Changes made to the Device ID while connected to the network require a power cycle of the device in order to take effect.
