Model LX908 Remote Alarm Panel
The purpose of the alarm panel is to monitor up to eight remote normally closed contacts, and give both
an audible and visual alarm if one or more of the remote contacts open. The remote alarm contact must
be a dry contact or damage to the main board will occur.
When the first remote contact opens, indicating an alarm condition, the alarm horn will sound and the
respective alarm light will come on. The horn can be silenced by pressing the silence pushbutton. The
alarm light will remain lit until the alarm condition is corrected.
If a second alarm condition occurs, the next respective light will come on and the horn will sound again.
This sequence of operation would continue for each of the eight alarms. In each case the audible alarm
can be silenced and the light remains lit until the alarm condition is corrected, and the remote alarm
contact returns to its normally closed state.
An alarm test pushbutton is provided to verify all of the alarm circuits are functioning. Depress and hold
the test pushbutton for three seconds, at this time all of the functioning alarm lights should be lit.
A green LED is provided to indicate if the rated AC main supply power is available.
The LX908 alarm panel can be provided with a NICAD battery backup as an option. The rated AC main
supply will act as a battery charger. If the battery is supplying the power, a red Led will be lit.
All unused alarms must be jumpered to the alarm common as shown on the field
connection drawing.
