Product Overview
The RP21C-A is a grab-and-go man-pack directional projector built for rapid-response voice and alert tasks. At 11.26 kg with a 573 x 248 x 306 mm shell, it funnels up to a Peak SPL@1m of 153 dB into a tight 15-degree forward cone that reaches 501 m in use and 1259 m at the fringe, sending clear spoken commands where a solo operator needs reach without flooding the sides like a round emitter. A paired operator handset runs the unit over TCP/IP on a cabled or radio link,it keeps custom audio ready to play. Fed by 12-30 V DC or 110-260 V AC, it clamps to masts or roofs for fast field setup across utility safeguarding, crowd safety, community alerting, and remote boundary watch.
Description of Characteristics
• Forward-Focused Output
Concentrating up to a Peak SPL@1m of 153 dB into a 15-degree forward cone, the unit throws intelligible speech and tone 501 m out (1259 m at the extreme), skipping the surrounding spill of round emitters.
At 11.26 kg and a 573 x 248 x 306 mm shell, it is slung and shifted by one person for nimble, on-demand coverage.
• Handset Remote Operation
A paired operator handset commands the unit over TCP/IP, on a cabled or radio connection, so an operator can manage broadcasts from cover or inside a car cabin.
• Custom Onboard Audio
It retains mission audio - speech, tone, and dissuade clips - triggered on demand without external players.
• Car or Fixed Supply
The 12-30 V DC input draws from a car socket, while 110-260 V AC via adapter suits fixed sites, switching the unit between mobile and stationary roles.
• Field-Hardened Shell
Sealed to IP65 and rated for -40 C to +60 C operation (5%-95% humidity, -50 C to +70 C storage), it withstands dust, rain, and temperature swings in outdoor duty.
