Description
The NBG-10 Series is a non-coded, dual-action, normally-open manual pull station with the following options: NBG10A (with
AUX. switch); NBG-10L (with key for reset); NBG-10P (with key for presignal or test); NBG-10N (without terminal block);
NBG-10WP (BG-10 enclosed in a weatherproof backbox).
NBG-10 Series Operation
When the dual-action door is pushed in and the handle pulled down, the N.O. push-type switches will close. The handle cannot
be restored to its normal position until the station is manually reset by unscrewing the hex screw and pivoting the case
downward, away from the backplate. When the handle is restored, return the case to its normal position and secure with the
hex screw. Note: The NBG-10L utilizes a mechanical key instead of a hex screw. The microswitch of the NBG-10P/T is
activated by rotating a key clockwise. The key cannot be removed while in this position.
