NBG-12LX Fire Alarm Pull Station Addressable

Notifier (Honeywell) NBG-12 Series Introduced circa 2010

Notifier NBG-12LX addressable fire alarm pull station.

Common Applications

The red pull-down handle you see on every wall in commercial buildings. Pull down to activate the fire alarm. Addressable means the fire alarm panel knows exactly which pull station was activated — critical for large buildings. Key-reset to prevent prank activations. ADA compliant handle height and force. Building code requires one within 200 feet of any point in every commercial building.

Installation Quick Reference

Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).

Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.

Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Troubleshooting

Button doesn't respond when pressed

Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.

Works intermittently

Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.

Button feels mushy or doesn't click

The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
