NOTES:
1. To modify the text size and color of the text in the
blocks, you must “unprotect” the document. Do not reprotect the document; otherwise all the information that
was typed in will be lost.
Figure 8. Keypad Button Layout
2. Before printing on the included slide-in labels, print a
test page on plain paper to verify that the positioning, the orientation, and the information are correct.
To check the printed paper, lay it behind the included slide-in label sheet and verify that the print is in
the proper location. Because printers vary, you may need to adjust the margins in the page setup to
center the printed text within the perforated strips.
Install keypad slide-in labels as follows:
1. Separate the slide-in labels along the perforated lines on the sheet.
2. Fold the tab at the end of the slide-in label so that it is perpendicular to the rest of the label.
3. Slide the label into the appropriate slot opening located at the top of each of the button columns.
4. Repeat the above steps for the remaining labels.
To remove the keypad slide-in labels, proceed as follows:
1. Locate the tab at the top of the label and pull it out from behind.
2. Slide the label out using the tab that has been exposed.

Operation
The access panel operator is capable of voice communication and system control functions. The
following paragraphs provide a general overview of the available access panel features. Operation details
for the access panel are determined by software programming at the ADVANCE System control cabinet.
In general, the access panel handset is used for paging and party line communication. Push-button
switches are used for a variety of system control functions.
Push-Button Swi tch Summary
Each push-button switch function and LED indicator (next to the switch) is programmable. Typical
switch functions include alarm activation/reset, paging zone selection, or beacon activation/reset, but
other special functions are available through system programming.
Paging and Party Line Operation (typical )
Complete the following steps to make a page announcement from an access panel.
1. Lift the handset from the cradle.
2. Select the desired paging destination(s) or all call. The LEDs of the selected switches illuminate.
3. Press and hold the handset pressbar switch.
4. After the short “wait” tone is heard, speak directly into the microphone to broadcast your
announcement.
5. Release the handset pressbar when complete.
6. Upon releasing the pressbar switch, the access panel handset is connected to party line 1. The paged
individual(s) responds by picking up a station’s handset and turning the selector switch to party line 1.
Party line communication is not broadcast over the system speakers. Other individuals can also pick
up a handset and join the conversation at any time. Always return the handset to the cradle following
a page or a party line conversation.
OTE: To cancel any selected destination push-button switch, press the switch again and the LED will
N
extinguish. The access panel automatically deselects the paging destination(s) after a page is completed.
Paging Confirmation Tones
When paging from an access panel, a short “wait” tone will be heard in the handset receiver when the
page switch is depressed. Do not talk until the tone ceases. When the tone ceases, the page request has
been granted by the system control cabinet. If a busy tone is heard, the page request has been rejected and
the operator must try again later. The page rejection occurs when a higher priority page or alarm is in
progress at the time of the page request.
Timeout Features
Each access panel can be programmed to limit handset paging time and the amount of time the handset
can be in use or off-hook. These features are often used to identify handsets that have accidentally been
left off-hook or to restrict an access panel from being in use for prolonged periods of time.

Page Timeout – This sets amount of time the access panel can generate a page. If the limit is exceeded,
the page will cease and a busy tone is heard in the handset receiver. A trouble report will be sent to the
control cabinet. If the handset page switch is released, the page timer is reset. The page timeout can be
disabled or set for 1–25 minutes in 1-minute intervals.
OTE: By default, the page time-out for access panels is disabled.
N
Off-Hook Timeout – This sets amount of time the access panel can be in use or off-hook. If the limit is
exceeded, handset operation will cease and the access panel will be placed electrically on-hook. A
trouble report is sent to the control cabinet. The handset remains inoperative until it is physically placed
back on-hook. The off-hook timeout can be disabled or set from 1–25 minutes in 1-minute intervals.
N
OTE: By default the off-hook time-out for access panels is disabled.
Handset Paging Pre-announcement Tones
An access panel page can be preceded by one of two available tones. Tone selection is based on the
system mode of operation at the time of the page (normal or alarm). The “Splash” is a Hi-Lo tone
approximately 1 second in duration. The “Alert” is a swept tone approximately 1 second in duration.
OTE: By default, the splash tone is enabled.
N
Activating an Alarm
Activate an alarm from the access panel as follows:
1. Select the desired destination using the zone push button(s) if configured. The destination could be a
single zone, a group of zones, or all zones. The LEDs of the selected zone switches illuminate.
2. Select the appropriate alarm push button. The alarm broadcasts into the selected zones, and the LED
of the selected alarm illuminates during the broadcast.
3. For access panels equipped with an E
NTER push button: Press the ENTER push button after pressing
the alarm push button to activate the alarm in the selected zones.
OTES:
N
1. To cancel any concurrent alarm, press the C
ANCEL CURRENT push button or the RESET ALL push
button. This cancels all alarms that are currently playing or that are in the alarm queue.
Alarms may also be configured to play immediately when the alarm push button is pressed. In this
2.
case a zone selection is not required. The alarm’s destination is pre-configured in the system
programming.
Sonalert
The sonalert is an audible indicator and its control signal is paralleled with LED output #20. It is
typically configured to sound when the access panel loses communication with the ADVANCE System
control cabinet.
Lamp T est F eature
The lamp test feature is used to verify that the access panel indicators are functioning properly. When the
L
AMP TEST push button is pressed, the switch indicators illuminate, and the panel sonalert will sound.
OTE: The LAMP TEST push-button does not include an indicator.
