Alarm Operation Operating Instructions
 INV ID - indicating that an incorrect device code (Type ID) has been programmed for an
installed device (for example, Photo has been programmed but an Ion detector has been
installed)
 SW TBL - indicating a module has failed the testing of its Class A switching relay
• Fourth line in display:
– Time; the current time in this example is 10:00A which represents 10:00 AM
– Date; the current month, day and year in this example is 10 for October, 09 for the 9th day of
the month and 13 for the year 2013
– Device Address; 1D001 in this example 1 represents SLC Loop, D represents a detector, and
001 represents device address 001
Pressing the Acknowledge/Step or Alarm Silence key will cause the pulsing piezo to silence and the
system Trouble LED to change from flashing to on steady. This block acknowledgment occurs
regardless of the number of troubles, alarms and supervisory events active in the system. When the
Acknowledge/Step key is pressed and at least one new alarm or trouble exists in the system, the
‘acknowledge’ message is sent to the printer and history file. If the trouble clears, either before or
after the Acknowledge/Step key is pressed, the ‘clear trouble’ message is sent to the printer and his-
tory file.
If all troubles clear and there are no supervisory or fire conditions active in the system, the system
returns to normal mode operation and the System All Normal message is shown on the LCD display
and sent to the history and printer files. The auto-restore feature will restore cleared troubles even
if the troubles were never acknowledged. Note that pressing the Alarm Silence key when only trou-
bles exist in the system will have the same effect as pressing the Acknowledge/Step key except the
Alarm Silenced LED will light.
4.5 Alarm Operation
Alarm operation is similar to trouble operation with the following differences:
• The piezo sounder produces a steady output as opposed to a pulsed output
• The Fire Alarm LED flashes 1 second On and 1 second Off
• The LCD displays Alarm along with the device name, type, address, adjective/noun, associated
zones and time/date
• Communicate the alarm to the Central Station
• Alarms latch and are not allowed to clear automatically
• Alarms activate software zones if so programmed
• Timers for Silence Inhibit, Autosilence and Trouble Reminder are started
• Alarms activate the general alarm relay and general alarm zone Z00
• The trouble relay is not activated
• Store event in history buffer
• Terminate upload or download communications
A typical alarm display would be as illustrated below:
Note that the device type, which in this example is PULL STATION, can be any other programma-
ble alarm type.
The information displayed in the above example provides the following information:
