Application Information
1.1 Description
The SP4 Telephone Zone Controller (SP4-TZC) controls the zone paging capability of the
SAFEPATH
®
4
Multi-Function Facility Communications System. It is used in conjunction with the SP40 and the SP4-APS
(SP4 Addressable Paging Splitter). Audio Boosters SPB-80/4, SPB-160, and SPB-320 can be used in
conjunction with the SP40. Each audio booster can use additional SP4-APS splitters, increasing the number of
possible paging zones.
The SP4-APS splitter in conjunction with the SP4-TZC allows the End User to make audio zone specific
telephone pages and/or have audio zone specific Background Music (BGM) on a Wheelock
SAFEPATH
®
4
Multi-Function Facility Communications System. This can occur as long as the system is not broadcasting a
pre-recorded message or when the live microphone is in use. The selective paging and BGM functions are
controlled by the SP4-TZC over a RS-485 based digital control network. It also provides a means for
expanding one supervised audio output zone to 4 CLASS “B” or 2 CLASS “A” supervised zones. The
maximum number of CLASS “B” zones in a system is 68. The maximum number of CLASS “A” zones in a
system is 34.
The SP4-TZC can be used with or without the SP4 Telzone Programmer 2 software. The features available
without using the software include the use of Individual Zones and Fixed Zone Groups for Zone Paging, and
Background Music on all zones. When using the SP4 Telzone Programmer 2 software additional features
include Logical Zone Group paging, disabling of Zone Paging (All-Call Paging), user programmable Zone
Setup options, and customization of Individual Zones for Background Music.
An Individual Zone is one of the individual outputs from an SP4-APS splitter. The SP4-APS splitter can
produce either 2 CLASS “A” or 4 CLASS “B” zones.
A Fixed Zone Group consists of 2 CLASS “A” or 4 CLASS “B” zones on each SP4-APS splitter. For example,
if the first SP4-APS splitter is used to cover the zones in the warehouse area the Fixed Zone Group for that area
can be paged by keying the two digit Zone Code “71” on the paging phone. The Zone Codes for Fixed Zone
Groups are 71 through 87 with each Zone Code matching the order of the splitters.
When used with the SP4 Telzone Programmer 2 software, the SP4-TZC in conjunction with the SP4-APS
splitter is capable of programming up to 9 Logical Zone Groups for audio paging. A Logical Zone Group
consists of 1 to 5 Individual Zones and/or Fixed Zone Groups. It can also program any Individual Zone for
Background Music. The two digit Zone Code for the Logical Zone Groups are “91” through “99”.
Paging an Individual Zone, a Fixed Zone Group, or a Logical Zone Group is accomplished using a touch-tone
phone connected to a page port or a touch-tone stand-alone phone. The paging telephone is connected to the
SP4-TZC allowing it to key Zone Codes each consisting of two-digit DTMF tones. See Table 1 for the dialing
scheme. Any Individual Zone or Fixed Zone Group that is not known by the system will result in a no page
condition and the SP4-TZC will start the paging process over.
The SP4 Telzone Programmer 2 software is the second major release of the software, that is designed to operate
with an SP4-TZC having firmware version 2.xx. It is NOT backwards compatible with an SP4-TZC having
firmware version 1.xx. For SP4-TZC's having firmware version 1.xx, version 1.x.x.x of the SP4 Telzone
Programmer software must be used to ensure proper operation.
