Merge/Isolate Zone Control System
Page 3
Overview
Merge/Isolate System
The function of the Merge /Isolate system is to merge and re-isolate up to five (or ten with
expansion unit) zones of Guardian Page/Talk or GAI-Tronics Page/Party®system Stations and
Amplifiers. The system is comprised of a Master Zone Control Unit (MICAB) and one to six
Control Console Stations (MICONs). Each MICAB has a five zone page line mixer, which
allows the master controller to simultaneously monitor merge requests through the page lines
of all zones. The system can merge 2, 3, 4 or all 5 zones and is also able to merge another
zone into a merged zone group later – for example zones 1 & 2 can be merged and zone 3 can
subsequently be added. The isolate function can be performed separately as well – for
example zone 2 can be re-isolated from zone 1 & 3 leaving them to converse alone. The
system has controls to merge and isolate all five zones in one step, which is very useful in
emergency situations. The system has the ability to be configured so that if an alarm occurs
and the operator needs to send a page, the alarm will be muted while the MICON is in paging
mode. When the Push To Page is released, the alarm tone returns to full volume.
The MICON has the ability to trigger and reset up to 10 alarm channels from an alarm
generator, such as Guardian’s AG17. It also displays two summary alarms in the form of LED
indicators. The inputs for these are located on the MICAB and are a simple dry contact format.
Some examples for use of the two alarms monitors are; the facility alarm activation, which
could show that an alarm has been activated somewhere in the facility, either from the MICON
or from an external switch. The other could be tied into a UPS or door switch or other sensor
as considered essential to provide a visual monitoring aid.
The MICAB has connections for a telephone interface which – with operator assistance –
allows telephone calls to be made and received.
The system has one set of Page & Talk merge bus lines – the common Page Line & one pre-
determined Talk Line. Separate merged zone groups is not achievable, only one group of
merged zones at one time can be performed.
The system can accommodate up to six MICONs working in parallel. It can also be expanded
with another Five Zone MICAB working in tandem for merging and isolating up to ten
Page/Talk zones. The MICAB can be configured by the factory for 120VAC, 230VAC or
24VDC operation.
The MICONS are phantom powered by the MICAB eliminating the need for a local power
supply for each MICON. The MICABs are rack mounted units with user access to zone
conductor terminations (one pair of page & one pair of talk wires per zone), Alarm Control, and
Telephone Interface terminations.
Each MICON can be programmed for a unique level of control which can range from a low
level monitor desk set with no control up to a full control unit. This offers the advantage of
limiting what alarms or zones a station can set, clear or merge.

WARNING – high voltages are present in this equipment when it is
connected to the power source.
Follow all appropriate electrical codes and use only approved electrical
fittings for the installation.
Install the MICAB in the rack.
If the Control System is being installed in a five channel system determine
which channel will be dedicated to the Merge/Isolate function.
See: Figure 2 -
Dimensions MICON &
MICAB
Ensure that none of the electrical connection circuits are live.
Following the color codes in the System Wiring Connections table connect
the Page Lines and the dedicated Talk Lines from each zone to the zone
connectors on the back panel of the MICAB.
Following the wire identification information in the MICAB to MICON Wiring
Connections table connect the MICON(s) to the MICAB. Up to six MICONs
can be connected to the MICAB.
See: Figure 11 -
Page/Talk System
Wiring (typical
application)
See: MICAB Back Panel
Connector Tables and
Installing Multiple
Merge/Isolate Controllers
(MICONs)
Connect the Alarm Generator. See: AG17 Manual
To reduce noise on the Page/Talk system, 33 Ohm resistors – usually
installed in a Line Balance Unit (LBU) – are connected across every page
& talk line in every zone in/near the MICAB. The MICON provides the
loading for all the page and dedicated merge talk lines. Resistors for the
un-merged talk lines should be placed near the MICAB and remote LBU’s
must not be connected.
See: LBU Manual
If a Telephone interface is to be connected into the system do so at this
time. See: PTTI Manual
Jumpers JP1, JP2, JP3, JP4 and JP5 are configured at the factory for the
most common setup. If changes to the system occur relocate jumpers to
the appropriate positions.
See: Figure 9 - MICAB
Jumper Settings
Ensure all connections are secure.
Connect the power supply to J1. The voltage is set at the factory to
120 VAC, 230 VAC or 24 VDC. Ensure that the power being supplied is
correct by checking the label on the back of the MICAB. Connect the
MICAB power cord to the proper power source then turn on the power
switch.
Program the system.
Adjust the front and back panel potentiometers.
See: Programming of
MICABs and MICONs
See: Potentiometer
Adjustments on the
MICABs
Test the system as described in the operation section. See: Operation

Guardian Telecom Inc. Installation Programming Operation
Merge/Isolate Zone Control System
Page 14
Potentiometer Adjustments on the MICABs
Back Panel access Potentiometers
The Page line impedance adjusting potentiometers for each of the isolated
zones are located next to the Zone connectors on the back panels of both
Master and Slave MICABs. With the Page Line not in use inject a test
signal into the Page Line. Adjust the potentiometer in the Line Balance
Assembly until the signal on the Page Line reads 0.5VRMS. If new
stations are added to a zone, the Page Line impedance of that zone should
be adjusted to adapt to the new load.
See: Figure 6 - Back
Panel Wiring
Connections
Front Panel access Potentiometers
The Merged Page line impedance adjusting potentiometer is located on the
front of the Master MICAB once the Plexiglas is removed. This adjustment
will affect the impedance of the merged page lines. Adjust it when the
system is first set up or when stations are added to the system.
See: Figure 7 - Front
Panel Adjustments
The mixed line signal strength adjusting potentiometer is located at the
front of the MICAB and is accessible once the Plexiglas is removed. All the
audio signals on the isolated and merged page lines are mixed and sent
back to the MICON speakers to monitor requests. A system may have one
to six MICONs. This potentiometer is utilized to adjust the mixed line audio
for the existing load (one to six MICONs). Adjust this potentiometer as
follows:
Using any MICON as a reference station set the speaker volume to a
maximum level.
Adjust the mixed line level potentiometer until the reference MICON picks
up lowest noise.
Page from one of the Page/Talk stations from an isolated zone. Listen to
the speaker volume on the reference MICON (with speaker volume to
max.).
Adjust the mixed line level pot until the speaker on the reference MICON
provides an acceptable audio level (~ 85dB @ 0.5 meter).
Adding or removing MICONs in the system may affect the speaker volume
of the other MICONs. If the volume control in the MICON cannot
compensate for the increase or decrease of the speaker volume, the
system may require re-adjustment of this potentiometer.
The data line Signal Threshold potentiometer is located at the front of the
MICAB and is accessible once the Plexiglas is removed. This adjustment
affects the received data signal strength detection threshold of the MICAB.
Adjust it until the MICAB can detect the instructions sent from the MICONs.
Ten Zone Merge/Isolate System Description
A Ten Zone Merge/Isolate System consists of two MICABs, and a maximum of six MICONs. Of the two
MICABs, one is configured as the master, and the other one as the slave. All six MICONs have the
same status in accessing the MICAB on a first come first served basis. The full capacity of the system
is ten zones. If the setup is less than six zones, one MICAB is all that is required.
The system supports an alarm tone generator, a telephone interface module and line balance
assemblies (omit).
The system has to be set up prior to operation.

Installing Multiple Merge/Isolate Controllers (MICONs)
Up to six controllers (MICONs) can be connected to the MICABs. MICON wiring
can be in parallel, series, or a combination of both.
MICONs can be desk mounted or wall mounted
If a MICON is to be desk mounted simply set it in position.
If a MICON is to be wall mounted remove the faceplate and secure the
base to the wall in the desired location, with the deepest dimension
towards the bottom. The handset retainer clips should be installed to the
handset cradle to hold the handset properly.
Tip: There are only five
connections for MICONs
on the MICAB. The sixth
MICON can be wired in
parallel with #5.
Caution: The electronic
components are secured
to the faceplate, handle
with care.
Wire the MICONs back to the MICAB.
Ensure all connections are secure.
See: MICAB Back Panel
Connector Tables
Program the MICON and the MICAB.
Test the system by merging zones as would be done during normal
operations.

MICON Programming:
Once the system is powered up the MICON is ready for programming its function registers. To enter
Programming Mode, press the [PVT] key and the [LMP TST] key simultaneously. The LCD display will
respond with a greeting message and then the main menu.
1 = MICON, 2 = MICAB
3 = AlrZn, 4 = STORE
1. MICON setup:
Press key [1] while in the main menu to program the existing MICON. Once key [1] is selected the
screen will display the register number and its setting. Enter or change the setting by keying in the
proper numeric key.
Any out of range entry will be prompted with a message.
Use the [VOL UP] or the [VOL DWN] to scroll through all the other registers.
Once all these registers are verified to be correct, press the [PVT] to get back to the main program
menu.

Notes:
1) All MICON stations have to be programmed with a station number. The station numbers range
from 1 to 6. Only station number 1 can get access to program the other functions of the MICAB.
There cannot be two stations with the same station number. Stations have a default setting of 8 to
ensure that adding a new station does not conflict with existing stations. The default setting must be
changed to a number between 1 and 6 that has not been assigned to another station.
2) Once Reg01 is stored with 0, all the red alarm function keys will be disabled. Pressing these keys
will result in receiving the deny message on the display.
3) Only English is supported in this version.
4) Use volume keys on the keypad to alter the initial volume.
5) Once Reg04 is stored with 0, all the blue zone function keys (excluding the [PVT] key) will be
disabled. Pressing of these keys will result in receiving the deny message on the display.
6) Setting Reg05 to 0 or 7 will restore all the registers back to the default settings of the MICON.
MICAB programming:
Programming the MICAB is done in two stages. First, use the MICON (station 1) to register all the
settings that are available in the MICAB. Once the system registers are verified as correct, transfer
these registers from the MICON to the MICAB. Below is the main menu on the MICON:
1 = MICON, 2 = MICAB
3 = AlrZn, 4 = STORE
2. MICAB setup:
Press key [2] while in the main menu to program the MICAB function registers. Once key [2] is

4. Transfer the registers settings in the MICON to the MICAB:
Pressing key [4] while in the main menu will cause the MICON to send all the register settings to the
MICAB. If the master MICAB and the slave MICAB exist they both will be updated with the new
settings. If the transfer is successful the MICAB will blink all the zone lights.
Operation
Requesting a Merge:
The caller first sets the Talk Channel Selector to the dedicated Talk channel. A request for a merge is
made by the caller making a Page to the Control System operator in the normal manner. The system
circuitry has a five zone mixer therefore a Page from any zone will be heard by the operator. If the
requirement is for a simple Merge the information can be conveyed in the original Page. If the
requirement is more complicated – say an inquiry as to the Zone in which a particular individual is
located – the Page can simply ask the operator to speak on the dedicated line. In this case the
operator can check on the LCD display for the origin of the page zone; then press the button to merge
the Zone from which the call is coming, and can then have a conversation with the caller. The operator
can page the person being called and the person requesting the merge will know that the merge has
been made when the called party comes on the line.

Alternatively the operator can merge the zones requested and the caller can make the page and wait
for the called party to come on the line.
If a merge request comes in from an unmerged zone while a merge of other zones is in progress the
operator can merge the zone from which the request is coming with the merged zones and butt in, to
convey to the person that the request cannot be processed at that time. The MICON display will
indicate if the caller has a handset picked up in their zone by illuminating the respective zone number.

Setting and Cancelling Alarms
If an AG17 Alarm Tone Generator or similar is connected into the system the Master Controller can
generate alarms on the Page lines of selected zones.
Trigger Alarms:
To trigger an alarm press [ALM SET] key, then select the alarm channel through the numeric keys. If
another [ALM SET] key is pressed prior to any numeric key being entered, the MICON will exit the
alarm setup and return to the standby state.
Once the alarm is triggered the zones associated with the alarm will be merged. The red General Alarm
LED will be on to alert the operator for alarm status.
