Chapter Five: Telecontrol and Two-Way Audio

The ProGuard800 control panel offers a range of Telecontrol features that provide remote
access via the telephone. These features include Two-Way Audio, remote
arming/disarming and cancel siren activation. This chapter explains these features and
their operation procedures.
Telecontrol features can be separated into two fundamental groups; incoming and
outgoing calls. These groups differ in their associated features.

5.1: Incoming Calls

The control panel can receive incoming calls from either the user or monitoring station
operator. Users may use this feature as a convenient way of contacting their family,
operating their system or to check their home when they are away. Additionally, the
monitoring service can contact the user in the event of an emergency or use this feature
for listen-in alarm verification.
For any of the incoming Telecontrol features to function, Telecontrol must be enabled in
the Communication Options section of the Programming menu – see 10.6.10: Incoming
Calls.
5.1.1: User Code Verification
To prevent unauthorized attempts to connect with the control panel, there are two user
codes designed for use with the Telecontrol features. The Telecontrol code enables the
user to establish communication with the control panel at any time. Additionally, the
Monitoring station TWA Code is used exclusively for Two-Way Audio alarm verification
and is only valid for a ten-minute period following an alarm.
5.1.2: Incoming Calls via PSTN
In the case of PSTN communication, the control panel often shares a line with regular
telephone handsets, an answering machine or a fax machine. It is therefore important
that the control panel distinguish between calls so that it knows when to pick up the
relevant call. For this purpose the ProGuard800 employs a double call method.
To connect to the control panel using the double call method:
1. Dial the telephone number of the line connected to the control panel.
2. Wait for two or three rings and hang-up.
3. Wait at least five seconds and dial the number again; on the second
ring, the control panel picks up and sounds two DTMF tones.
5.1.3: Incoming Calls via a Cellular Network
The Cellular Communications Module has its own individual telephone number and
therefore, the double call method is not needed. In this case, the user or monitoring
station operator may call the control panel directly.
