N553A Bulb Extraction Tool The Alpha Communications® model N553A bulb extraction tool is used primarily with our lighted annunciator units, for bulb extraction and replacement. It can be used with our CM800, DS100, NC110N, NC150N, NC150R, NC200N, SB5000 and other annunciator panels, using our model LI014 bulbs, (or LI014K kits) or the equivalent physical size.
While not required for system operation, most specifications call for the installing contractor to provide the facility with any “special tools” required for proper system maintenance.

We recommend that the installing contractor provide a model N553A bulb extraction tool, with each master annunciator station.
