The PowerMax range of wireless security solutions meets widely varied residential and commercial safety and security needs.  It is ideal for residential and small commercial properties which require simple and straightforward installation and protection requirements.

Based on Visonic’s PowerCode technology, the PowerMax family includes a variety of wireless control panels and wireless peripherals, including indoor/outdoor motion detectors, safety sensors and a wide range of personal emergency transmitters.  

MCS-720B is the ideal indoor siren for residential and light commercial buildings, particularly where outdoor sirens are prohibited.  This cost effective, two-way wireless siren produces all alerts, with differentiated alarm sounds for intrusion and fire. The extremely strong siren sound and built-in high-power white strobe light ensure the alarm gets noticed.

Fully-supervised with no external power supply required, the siren unit can be installed at a distance from the control panel, allowing the panel to be placed in a concealed location where an intruder cannot see it.  Because the siren produces all alerts, the control panel's location remains a secret, preventing an intruder from discovering and disabling the panel's alarm siren. The siren's two-way communication maintain continual supervised communication with the control panel.

MCS-720B is perfect for use in homes and apartments, vacant vacation homes and in small stores. Featuring an elegant, thin-profile design, it fits unobtrusively in any décor.  The easy, cable free installation guarantees time and cost-efficient implementation and servicing.
