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-740 two-way, self-powered fully wireless outdoor siren (IP55) provides the perfect security solution for homeowners looking for an external siren that is both affordable and easy to install.  It excels in offering simple cable free installation.

The siren's two-way, fully supervised communication with the control panel and two diversity antennas assure highly reliable operation and optimal wireless performance, including visual and audible notifications of intrusions, fire alarms, low battery voltage, and communication disruptions.  In addition, the siren provides auditory squawk notifications of arming and disarming the security system. In the event of an alarm, the siren sound is extremely loud, ensuring the alarm is noticed.

The sleek design ensures the MCS-740 siren is clearly visible from almost every angle. This makes it highly effective at alerting and deterring potential intruders, while maintaining the clean external look of any building.
