Trouble-shooting the ARM

To trouble-shoot the ARM, it is recommended that the following points be investigated:
• If the output volume is too high or low, adjust the output volume using level control R233.
• Ensure that the external switch(es) correspond to the ARM settings such as normally open
and normally closed. This ensures that the ARM correctly recognizes the alarm signal.
• Ensure that the connections at the back of the ARM have been properly made.
• When using optional external LEDs, ensure that the LED is functioning correctly, and that
it is properly connected with the correct polarity.
Note: Incorrect settings on the DIL switches (priority level, zone assignement or signal settings) on an
ARM may cause the input to function incorrectly or not at all.
