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 Switch 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.
: To cancel any selected destination push-button switch, press the switch again and the LED will

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.
