Galaxy 3 Series Programming Manual
When one of these conditions is detected, a LINE FAIL message is sent to the Galaxy 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 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 will continue; if esc is pressed a
line fail will immediately be logged. If the system is unset, 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 period. Subsequent line fails are
displayed as COMM LINE FAIL messages on the keypad for the duration of the condition and are re-
corded in the event log.
If an alarm occurs during a line fail condition, then the programmed bell delay for each of the groups is over-
ridden (refer to option 51.02 = PARAMETERS.Bell Delay).
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.
If the communication attempt is unsuccessful, the LED flashes rapidly for three seconds. The communicator
then waits for a short period before redialling the number (or the second telephone number if the Receiver
option has been programmed as Dual or Alternate ). When the Fail To Communicate option is left at the
default setting of 120 seconds, a communication Fail will be recognised if there has not been a successful
kiss-off, irrespective of the number of failed attempts. Bell Delay (parameter 51.2) is overridden when this
condition occurs.
The FAIL TO COMM parameter has 5 time values:
1 = 60 seconds; 2 = 120 seconds; 3 = 180 seconds; 4 = 240 seconds; 5 = 300 seconds.
NOTE: If the Receiver option is programmed as Dual then successful transmission must be made to both
telephone numbers.
12 Remote Access
This option defines when and how Galaxy Gold remote servicing will operate. The options are described as
follows.
1 = Access Period
This option determines under what conditions the remote site can be accessed by the remote Galaxy Gold
operator. There are four modes:
56 - Communications (cont'd)
