Audio Capture; Audio Playback; Audio Overwrite/Retain Options; 2-Way Audio Sessions - Tyco HSM2955R Guía De Usuario

4.1 Audio capture

The HSM2955(R) module records audio before the alarm condition/trigger and programmable up
to 4 minutes after the alarm/trigger condition. Once an alarm condition/trigger has occurred, the
module continues to record until a connection to the monitoring station is established. The module
starts a new recording once the central station has listened to the recording and hung up and/or
terminated the session with [*] [099]. The audio module combines recordings from all enabled
stations into one audio file. Note: Please check with the distributor for availability.
Pre-alarm audio capture
The HSM2955(R) module is continuously recording audio. The module retains up to 16 seconds of
recording preceding an alarm condition or trigger. All stations with recording enabled will
contribute to the saved file.
Post-alarm audio capture
The module starts recording when a 2-way audio enabled event occurs. The duration for the audio
recording can be programmed in section [616]. The recording is saved until another audio
overwrite condition occurs. All stations with record enabled will contribute to the saved file.
Subsequent alarm audio capture
Subsequent alarm conditions/triggers do not overwrite the recorded audio until after the recording
has been listened to by the monitoring station or if another audio overwrite condition occurs.
NOTE: The alarm in memory may not represent the most recent alarm.
NOTE: An Entry Delay does not initiate a post alarm recording.

4.2 Audio playback

When the operator enters [*][1][6] the HSM2955(R) module will play back up to 16 seconds of the
pre- alarm audio followed by up to 4 minutes of the post- alarm audio. Once the playback has
completed, the module will sound the end tone and return to "Talk to All Stations" mode. Note for
Panic and Duress alarms, the module will return to "Listen to All Stations".
NOTE: The central station operator cannot terminate playback, the entire audio file must be played.

4.3 Audio overwrite/retain options

Once an audio overwrite event occurs, a new recording is saved over the existing audio. Possible
audio overwrite events:
Once playback is complete and the central station operator enters [99] to disconnect or
l
hangs up after playback.
When the programmable overwrite timer has been set
l
If an alarm is canceled with a valid access code during a transmission delay.
l
If playback is complete and the operator enters [88] to disconnect and enables the callback
l
window, the audio is saved.

4.4 2-way audio sessions

Audio verification session via PSTN
If an event programmed for 2-way audio occurs, the panel will send a 2-way audio initiating signal
to the central station. The HSM2955(R) will then begin the 2-way audio session via the PSTN line.
A tone is sent to the central station to indicate the 2-way audio session has started.
The 2-way audio session duration is 90 seconds.
NOTE: For UL/ULC listed installations the maximum duration of the 2- way audio session shall
not exceed 30 seconds.
Audio verification session via cellular/ethernet callback
If an event programmed for 2-way audio occurs, the panel will send a 2-way audio initiating signal
to the central station via the Cellular/Ethernet communicator. The call- back telephone number is
programmed using the communicator and sent with the alarm signal to the central station. Either
the Cellular or PSTN telephone number can be used. Once the central station operator calls the
telephone number, a tone is sent to the central station to indicate the 2- way audio session has
started.
NOTE: If using the 3G8080(I) /CD8080(I) /TL880LT/TL880LE/TL8803G, the central station is
called directly.
Audio verification session single alarm via one phone number
If an event programmed for 2- way audio occurs, the control panel communicates the alarm to
Phone #1, and the 2-way audio session is initiated immediately.
