Description
The Alpha LI424B strobe is a high intensity remote visual signalling device which is typically used with the Alpha IA543 amplifier apartment intercom systems, and optionally with the Alpha IA502 multi-entrance transfer relay(s). Due to its versatility, the LI424B can also be used as a stand-alone device, which can be triggered by a dry contact pushbutton or dry contact relay closure.
The unit is primarily for use in locations where hearing-impaired persons require supplemental call notification, but can be used anywhere that a visual indication of an incoming call is desired. The bright strobe light flashes once a second for approximately 20-35 seconds when an incoming call is detected (depending on amperage of the 24VDC power supply).
The device can be installed onto a standard 4-inch square electrical box or similar indoor openings. It is not a weatherproof device and therefore should not be used for any outdoor applications. Installation is facilitated by use of simple connections to the pre-mounted circuitry and a complement of mounting hardware.
