Answer:
The NBG-12LX utilizes a dual-action sequence requiring the user to push in and pull down the handle, which latches down and reveals the word 'ACTIVATED' in yellow. To restore normal operation, an authorized key must be used to open the door, which automatically resets the handle and switch mechanism upon closure.
The Notifier NBG-12LX manual station incorporates a patented dual-action mechanism to prevent accidental or nuisance activation in high-traffic commercial environments:
- Dual-Action Activation: Pushing in and then pulling down on the handle unlatches the internal switch, latching the handle down with the word 'ACTIVATED' appearing in bright yellow at the top and the bottom handle edge protruding outward for clear visual recognition.
- Keyed Reset & Inspection: The pull station is non-coded and cannot be restored to normal without an authorized key. Maintenance staff can open the front door using the key to set rotary addresses or conduct routine functional testing without initiating an alarm condition at the panel.
- Status Indication: A built-in bicolor LED visible through the handle provides polling status—flashing green during normal polling on FlashScan loops and latching solid red when the station has been actuated into an alarm condition.
- Accessibility Compliance: The handle features Braille lettering and meets ADA specifications with an activation force threshold under 5 lbs.
