Selective Operation
Selective operation allows “addressable” access to each paging module using DTMF signaling (DTMF
Selective) or Two-Tone signaling (Two-Tone Selective). Each paging module can be programmed with
up to eight different addresses. Upon receiving a valid DTMF or Two-Tone code, the paging module
becomes active and will broadcast any audio received from the transmitting device. The paging module
returns to the inactive (sleep) mode when the transmission is complete and a pre-programmed hold time
expires.
By assigning a combination of addresses to each device, the overall system can be segregated into
multiple broadcast zones. In a typical multi-zone system, three access codes are assigned to each module.
 Address 1 – is always a unique address assigned to only that paging module. By using this access
code, an individual paging module is activated.
 Address 2 – could be an address assigned to a group of paging modules located in the same speaker
broadcast zone. When received, the group of paging modules is activated simultaneously. This
access method is used when an audio broadcast is required to a particular broadcast zone.
 Address 3 – could be an address assigned to all paging modules in the system. By using this access
code, all paging modules are activated simultaneously when a system-wide audio broadcast is
required.
DTMF Selective with Manual Switch
Requires an external control input to activate (wake up) the paging module. Once active, the unit must
receive a valid DTMF address. Upon receiving a valid address, the paging module will broadcast any
audio received from the transmitting device. Removal of the activation input returns the paging module
to the inactive (sleep) mode.
 For hardwired installations, the control input activation must be in the form of a voltage–free (dry)
contact closure.
 For RF installations, the control input activation is provided from the “RF carrier detect” control
circuit of the integral radio receiver.
GAI-Tronics CARD Suite Programming Software is used to assign the operating mode and DTMF
addresses. Valid DTMF addresses can contain up to eight digits (0–9) followed by the “#” symbol. The
“#” symbol is automatically inserted by the programming software. Each paging module can be
programmed with up to eight different addresses.
DTMF Selective with Audio Switch
This mode is used for hardwired installation where a contact closure is not available from the transmitting
device. In this case, the paging module ignores the input contact and constantly monitors the audio line
for a valid DTMF address. Upon receiving a valid address, the paging module will broadcast any
subsequent audio received from the transmitting device. The paging module returns to the inactive
(sleep) mode after audio from the transmitting device stops for a pre-programmed time.
Two-Tone Selective
GAI-Tronics CARD Suite Programming Software is used to assign Two-Tone access codes. Valid access
codes contain two frequencies in the 400–2700 Hz range. Each paging module can be programmed with
up to eight different codes. By assigning a combination of access codes to each device, the overall system
can be segregated into different speaker broadcast zones as described above for DTMF signaling. Two-
Tone signaling is only applicable for RF installations. Contact the Service Center for instructions in using
CARD Suite to set up Two-Tone Selective.
