The UCT-WLN series of siren controllers allow third-party devices and sirens from other manufacturers to be controlled and monitored from Federal Signal SS2000+, Commander®, CommanderOne® and CommanderOne LE siren control products. The UCT-WLN model series are optimized to seamlessly integrate Whelen® Vortex, Omni, Hornet, and WPS Series sirens with the advanced features of Federal Signal’s siren control and status monitoring systems to provide full control and status monitoring capability.

Communication options are available for conventional High-Band, UHF, 800 MHz, Digital P25, and 4G cellular networks. Federal Signal’s FSIoT unique cellular multi-carrier communications platform utilizes AT&T®, Verizon®, and T-Mobile® with automatic carrier selection to dynamically optimize reliability and performance. In addition to multi-carrier redundancy, additional communications redundancy can be obtained by combining cellular and RF communication options within the Universal Controller.

The UCT-WLN Controller and communication devices are housed in a lockable NEMA 4 enclosure, rated for indoor/outdoor use. A small interface PCB mounts in the Whelen siren controller to minimize external field wiring by using an I2C buss instead of discrete wiring, simplifying installation.
