Action When Tamper Detected (Supervision)

In addition to the main events, the device can be configured with
supervision to also execute one of the above three actions in case the
device goes offline due to wiring failure or after being tampered with.
For example, a tone could sound over the speaker(s), or a private
pre-recorded message could be sent to a specified phone extension.
The supervision configuration options will appear once a relay option
with supervision is selected. See the Electrical Specification section
for details on supervision detection circuit.

Speaker Volume/Mute

Apply an external switch (short-circuit) across the Relay Input
terminals in order to mute the speaker. This allows a temporary
"disable" switch to control the device if desired, for example in a
boardroom to block paging during important meetings.
If volume control is desired instead, use a 5k-ohm (or 10k-ohm)
logarithmic potentiometer (rated for 1 Watt) to set the current across
the Relay Input terminals. Volume steps are applied at 4mA intervals
based on a nominal 13V source voltage (40mA current-limited).
0mA = regular (full) volume, down to mute at 40mA.
Leave the Relay Input terminals open (no-connect) for regular full-
volume operation when in this mode.

Call Button

While the 8188 can be configured to play the WAV file only once, it
can also be enabled to play it continuously with just one touch on the
1202 Call Button. The action can then be stopped via the smaller oval
cancel button located below the main call button on the 1202.

Dialing Extension

SIP account required in Page Extension fields in order to make a call.

Interval Between Tones

Specify the time delay (seconds) between tones.

Maximum Tone Duration

Select the maximum tone duration. The tone will be terminated once
the maximum time is reached.
