VOCIA TELEPHONE PAGING ADAPTER (POTS-1)

The Vocia Telephone Paging Adapter 1 (POTS-1) facilitates a direct connection from two (POTS-1-2) or four (POTS-1-4) Plain Old Telephone
Service (POTS) lines, or POTS-based PBX telephone systems. The interface permits live, real-time paging using any Page Code within

the Vocia system. When calling into a POTS line, a number of software-congurable voice prompt functions are available including Page

Code selection, Zone status indication and Page Now indication. A DTMF sequence of tones can also be programmed in the software to be
associated with a Vocia Control Input Event.

In the event of a busy Zone status, the POTS-1 supports Page Stacking and Store-and-Forward message queuing.

The POTS-1 supports Pre-recorded Messages when a Message Server-1 (MS-1) is present in the system. The POTS-1 also supports
Emergency Paging functions when a Vocia Life Safety Interface (LSI-16 or LSI-16e) is present in the system.

Power

Caution – Due to potential energy hazard, connections to the Aux Power 24V DC inputs must be

made by qualied electrician or other qualied person as required to conform with all local codes.

The POTS-1 requires a 24V DC power source to operate, but is capable of accepting dual 24V DC inputs for redundancy. Both power
sources may be connected concurrently, however each must be capable of supporting the full 30-Watt load of the unit (inputs are not
intended to load-share). Loss or return of either power source will not result in an interruption to normal operation as long as one of these
power sources remains functional. Monitoring of all power sources is selectable via the Vocia software.

The power connector is a four-way 5.08mm standard header with mating pluggable screw terminal block with cable restraint.

Pin Function

1 DC Power 1 24V(+)

2 DC Power 1 24V(-)

3 DC Power 2 24V(+)

4 DC Power 2 24V(-)

Device ID

The rotary ID switches on the POTS-1 give the unit a unique Device ID. The switches are in hexadecimal format. All POTS-1 units must
have a unique Device ID to function within a Vocia Paging World (i.e. it is not possible to have two POTS-1 units with the same Device

ID of hex 07). To assign a Device ID of hex 07, turn the MSB switch on 0 and leave 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 in order to take effect.

Network

The POTS-1 is designed to be used in a single Vocia World and utilizes the Vocia CobraNet LAN to communicate with the rest of the Vocia system.

The unit has two monitored RJ-45 Ethernet network connectors that allow a redundant connection to be utilized if required. The primary
connection will always have priority over the secondary connection. Monitoring of the secondary connection can be disabled in Vocia software.

The RJ-45 connectors use two LEDs to indicate Ethernet link and network activity (see table below).

Left LED Right LED Description

None None No Data Connectivity or CobraNet activity

None Flashing green Link established

Solid amber Flashing green Link established and CobraNet activity detected. The unit is acting as a CobraNet Performer.

Flashing amber Flashing green Link established and CobraNet activity detected. The unit is acting as a CobraNet Conductor.

Flashing amber None CobraNet fault. Check cabling and conguration for errors.

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

switches and/or ber-optic cable can be used to further extend distances between units on a network. Please note that CobraNet limits

network extensions to seven hops (one-way transmissions) within a network.

POTS Connections

A Line and Set RJ-11 connection is provided per telephone line. These are wired in parallel and allow a local handset to be used on the Set line.
The pin listing below applies to both the Line and Set connectors.
