takes place when dialing on the alarm panel or on a customer phone, and no 1499 Hz tone (Contact
ID kissoff) or 2025 tone Hz tone (SIA kissoff) is received from the receiver.
After the conditions for a failed attempt are met, the 3G4000W connects the panel to the wireless
network to communicate the events. When the 3G4000W switches the line, it stays in this mode
until the panel has successfully communicated its events. If the panel communications are
unsuccessful and the panel has hung up, the 3G4000W exits takeover mode after 3 minutes.
On the next event, the 3G4000W restarts the error detection sequence before switching. The
3G4000W performs this sequence on any phone number that it detects on the line.
If necessarry, you can programme specific central station phone numbers into the 3G4000W. The
phone number programmed in the 3G4000W must exactly match the number dialed by the panel.
You can also programme the 3G4000W to look for a Contact ID or SIA kissoff after the system dials
these numbers. A telephone line monitoring trouble also activates when the PTM activates. At the
send of the call, the system sends a restoral.
Wireless communication sequence
When an alarm or other signal is triggered, the control panel goes off-hook and the following
actions occur:
1. The 3G4000W asserts a dial tone.
2. The control panel dials the number of the central station.
Note: Ensure that the alarm panel inserts a minimum one second pause, or that the dial
tone search feature is active before the control panel dials the number of the central
station. For more information, see
checks for a dial tone. For more information, see
3. The 3G4000W detects the DTMF dialing and stops the dial tone.
Note: The 3G4000W cannot decode pulse dialing and does not support pulse
communication formats.
Checking for a delay in the alarm panel
About this task: To check that the alarm panel has a minimum one second pause in the dialed
phone, complete the following step:
• In the control panel's Phone Number Programming section, enter hex E and then enter the
dialed phone number. For more information on the Phone Number Programming section
and to ensure that a delay is present in the alarm panel, refer to the control panel's Installation
Manual.
Checking for a dial tone
About this task: To check for a dial tone on the control panel, complete the following step:
• In the control panel's Phone Number Programming section, enter hex D and then enter the
dialed phone number. For more information on the Phone Number Programming section, refer
to the control panel's Installation Manual.
Contact ID format
About this task:
If the panel is programmed for Contact ID format, the system completes the following steps:
1.
The 3G4000W sends the required Contact ID dual-tone handshake to the panel.
