Alpha PK152 NC110/150/200N Annunciator Controller Unit

Deliver dependable nurse-call and area-of-refuge monitoring with the Alpha Communications PK152 annunciator controller unit. Designed as a central power and control module for NC110N/NC150N/NC200N systems, the PK152 converts routine and emergency calls into clear visual (steady/flashing) and audible (slow/rapid tone) signals so staff can prioritize responses quickly and efficiently. The unit supports up to 1A of field device load and can be expanded to 3A using the optional PK800A secondary power supply, making it flexible for both small nursing stations and larger security or intercom deployments. UL 1069 listing and integrated short-protection circuitry enhance reliability and help meet healthcare code requirements. Compact dimensions and surface-mount installation allow placement on finished walls or in an optional junction box, while red/green LEDs and plug-in wiring harnesses simplify installation and troubleshooting. Ideal for hospitals, long-term care, and building security systems that require robust annunciation and monitoring, the PK152 integrates smoothly into intercom, security, and surveillance workflows. Contact your Alpha Communications supplier to specify the PK152 for your next nurse-call or emergency annunciation project.
