GX-Series Control Panel Installation and Setup Guide
On selecting this option a warning message is displayed on the keypad, WARNING!!! ENT = SEND
MESSAGE. Press the ent key to send the engineer test.
The test attempts to transmit once for each selection of the option. If the test is not successfully transmitted,
the communicator does not attempt to resend. An unsuccessful transmission is not counted as a FAIL TO
COMMUNICATE.
NOTE: Activation of an engineer test will send a test signal via all GX-Series communication modules.
56.1.09 No. of Rings
This option determines the number of rings before the Telecom module answers an incoming call; the
programmable range is 1 – 20, the default is 10.
56.1.10 Line Fail
The Telecom module continually monitors the telephone line that it is connected to. This option determines
the line monitoring conditions that result in a LINE FAIL event being reported and recorded in the log. The
three line monitoring capabilities are:
1 = Line Volts (default Enabled): A line fail occurs if the voltage on the telephone line falls below
three volts, or the line is cut.
2 = Dial Tone (default Disabled):A line fail occurs if the Telecom module cannot detect a dial tone on the
telephone line, when a dial attempt is made. In this case the Telecom module records the line fail, but will
continue the call attempt even if no dial tone is detected.
3 = Incoming Call (default Disabled):A line fail occurs if the Telecom module attempts to transmit an alarm
while there is an incoming call.
NOTE: Any combination of the above options may be enabled or disabled at any time.
When one of these conditions is detected, a LINE FAIL message is sent to the GX-Series and is stored in the
event log, with the exception of line volts which is monitored for a further period determined by the value
programmed in parameter 51.68. If sufficient line voltage is restored within this period, no event will be
stored. If an attempt is made to set (arm) the system or part of the system within this period, the message
ALERT – LINE FAIL 1 ent = CONTINUE SET will be displayed. If ent is pressed the set (arm) will
continue; if esc is pressed a line fail will immediately be logged. If the system is unset (disarmed), the
COMM LINE FAIL message appears on the keypad display and a local alarm is sounded - the keypad
buzzers and on-board horn (if connected) are activated. If the system is set when a line fail condition occurs,
the message COMM LINE FAIL will be displayed when the system is unset. This will be accompanied by a
local alarm.
The local alarm is only activated for the first line condition of each unset (disarmed) period. Subsequent line
fails are displayed as COMM LINE FAIL messages on the keypad for the duration of the condition and are
recorded in the event log.
If an alarm occurs during a line fail condition, then the programmed bell delay for each of the groups is
overridden (refer to option 51.02 = PARAMETERS.Bell Delay).
56.1.11 Fail to Communicate
This option determines how long the on-board telecom module will attempt to gain a connection before the
COMM FAIL message is recorded in the event log.
When an alarm condition or event is to be transmitted to the monitoring station, the Telecom module
snatches the telephone line and dials the programmed telephone numbers. After a successful communication
the LED lights for three seconds, the module then releases the telephone line and reconnects any serially
connected equipment. This procedure is repeated for the second telephone number if the Receiver option
has been programmed as Dual.
NOTE: The Telecom module communicator snatches and holds the line until a successful attempt has been
made to the required telephone numbers or all the repeat attempts have been tried.
