LI424B
Overview
Ensure reliable visual notification where audible alerts fall short. The Alpha Communications LI424B stand-alone strobe unit delivers high-intensity visual signaling designed for security, surveillance and monitoring applications — especially where ADA or hearing-impaired notification is required. The LI424B operates on 24V DC and features a hi-brightness strobe coupled with built-in timer/delay circuitry so each activation provides consistent, attention-grabbing flashes without extra control hardware.
This compact security strobe light (5.5" H x 5.1" W x 2.1" D) mounts easily on walls or surfaces and consumes low power, helping lower operating costs while maintaining effective coverage in busy common areas, elevator lobbies, or entry vestibules. Installers benefit from flexible triggering via a dry-contact pushbutton or relay, and integrators will appreciate native compatibility with Alpha Communications IA543 amplifiers and IA502 transfer relays for apartment intercom and access-control systems.
Specify the LI424B when you need a dependable visual alarm for security systems, surveillance suites, or ADA compliance. Contact your distributor to order or to discuss deployment in your next monitoring or intercom project.
