The WAVE2 features a distinct hinged enclosure that enables the siren to be installed and affixed without needing to be dismantled. The WAVE2 can be mounted either vertically or horizontally, flush against the wall, or in a corner, all without the need for brackets or extra mounting tools. The three screw terminal block enables the WAVE2 to be connected without the need for soldering or stripping wires. The WAVE2 is also ideally sized for installation on a single gang electrical box. While wiring the WAVE2, link it to the siren or bell output of your alarm panel. Connect the (-) from the bell output to GND, while the (+) from the bell output should be connected to terminal #1 for a continuous siren tone, and to terminal #2 for a fluctuating or varied siren tone. The WAVE2 works with all 12V wired security systems and consumes up to 500mA while in alarm mode. This Honeywell siren is additionally UL approved for commercial theft. A siren is the key component of any security system, warning everyone nearby of a breach and typically frightening the intruder off. The simple-to-install WAVE2 provides the perfect blend of affordability and performance for all wired siren uses.
