The MCS-720 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.

The MCS-720 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 decor. The easy, cable-free installation guarantees time- and cost-efficient implementation and servicing.
