ABS-1TB

The NOTIFIER ABS-1TB is a deep annunciator surface backbox with trim cover, designed for mounting ACS series annunciators like ACM-16AT, ACM-32A, or LCD-160 modules in fire alarm systems.
Unlike the standard ABS-1B, its increased depth accommodates the AKS-1B keyswitch option, providing secure access control for remote annunciators while maintaining a professional finish.
