2-Way Audio Disconnect Option; Audio Control Telephone Key Functions - Tyco HSM2955R Guía De Usuario

Audio verification session during 2-way audio session via one phone number
If a second alarm occurs during a 2- way audio session, the module will follow the disconnect
option selected (Section [022] Option 6). If enabled, the module will not end the 2- way audio
session to transmit the next alarm. If disabled, the module will disconnect the session and send the
next alarm event.
Audio verification session alarm with two paths/redundant communications
When the redundant communications option is enabled, the 2-way session is assigned to the first
receiver programmed for 2- way audio. If PSTN and cellular communications are used for 2- way
audio, a 3-way connection between 2 operators and the HSM2955 module can be started. If another
alarm is triggered, the panel will transmit the events and audio based on the option programmed
for 2-Way Audio Disconnect (Section [022] Option 6) through the alarm panel.
Audio verification session alarm with two paths/parallel communications
When the parallel communications option is enabled, the 2-way audio event will be sent to all paths
with 2-way audio enabled. The connection will be established with the first receiver that responds.
If PSTN and cellular communications are used for 2- way audio, a 3- way connection between 2
operators and the HSM2955 module can be started.

4.5 2-way audio disconnect option

This section is accessed through the alarm panel, Section [022] Option 6. When this option is ON
the system will maintain the 2-way audio session if a new alarm occurs. When this option is OFF,
the 2-way audio session will be disconnected immediately when a new alarm is generated.
NOTE: This option applies to new events only. All non- alarm events (except Fire Troubles) are
communicated after the 2-way audio session has ended.
NOTE: For UL/ULC Listed installations the disconnect option must be turned OFF so any new
alarm event will have priority over the 2-way audio session.

4.6 Audio control telephone key functions

HSM2955(R) functions are controlled using the [*] key during a telephone session as per the SIA
Audio Verification Standard. Enter [*] followed by [0] or [1] to select a level (see below), followed
by the 1- or 2- digit key number of the desired action. If programmed, the alarm and talk/listen
options can occur from any partition on the system.
NOTE: When an audio verification session has been initiated, the module is in 'line hold' mode
and waits for the operator to press a touch-tone digit (only when Manual Bell Shut-off is selected).
NOTE: Use the disconnect key [99] or [88] to terminate a session before hanging up.
