Aiphone TWS-Z4 TW Series 1-Panel Solar Tower with Hooded Emergency Wall Box

For remote campuses, transportation hubs, and large outdoor sites that require dependable emergency communications, the Aiphone TWS-Z4 Solar Tower delivers a turnkey, wire-free solution. This emergency phone tower combines a Sun Surveillance aluminum tower with an Aiphone WB-HE hooded emergency wall box for IX-series intercoms, offering instantly recognizable, two-way emergency voice and visual alarm signaling. The integrated solar panel and battery bank (24V DC input) keep the intercom and beacon/strobe powered continuously, while a preinstalled Ubiquiti wireless access point enables secure point-to-point networking for monitoring, alarm reporting, and IP camera backhaul. Built for harsh outdoor environments, the TWS-Z4 features bright red EMERGENCY signage and a high-intensity beacon to speed responder visibility and improve site safety. NDAA-compliant and designed for easy installation where conduit or powered lines aren’t practical, this solar tower streamlines surveillance, security, and remote monitoring deployments. Ideal for universities, parking facilities, parks, and transit sites—contact us to discuss site-specific configurations or to request a quote.
