ELAN AUDIO - SENTINEL / RCU-01 RCU01R02 PAGE 11/49
4.9 Configure Local Alarms
To allow for local alarms using the ELAN local alarm interface you need to do the following.
• Exit SENTINEL.
• Find a free printer port on your computer
• Add a 'generic printer' using the standard windows printer configuration and the free printer port.
• Call the printer "Sentinel alarm'. Note: It must be called this exactly or SENTINEL will not work.
• To use the local alarm, enable 'Local Alarms' on the 'configure alarms' window.
• For each RCU that you require local alarms, configure the 'local alarm' bits required on the individual RCU
config window ( under the 'paging' tab ). When any alarm is received with local alarms enabled the selected
bits are bitwise OR'd together and output to the local alarm port.
• Pressing the 'local alarm ack' button will clear all local alarms.
ELAN can provide a suitable relay box. This unit is called the SAR-01.
The connections for the parallel port must be as follows, or you will get printer errors from Windows.
Loop pins 1 to 10.
Loop pins 18, 11 and 12.
Grounds are pins 18 to 25.
Outputs are pins 2 to 9, alarm1 to alarm 8 respectively. TTL outputs active high.
