DIP SWITCH SELECTION
The release device will provide a factory default delay of 10
seconds (to minimize nuisance alarms) before releasing the
fusible link chain upon alarm or power loss. A 4-position DIP
Switch found on the PC board within the release device can be
used to adjust the length of the delay to one of four preset delays.
The optional delay settings are as follows:
1 2 3 4
Factory default setting of 10 seconds shown.
ON
NOTE: Position 4 is unused and should remain in the OFF position.
Position 3 is used to select one of the two available voice messages.
