Tower-20AM Specifics

TOWER®-20AM MCW is a ground-breaking, anti-masking wireless mirror detector that provides unparalleled alarm detection in outdoor environments due to the unique patented technologies it employs. It is the first detector to prevent false alarms caused by outdoor interferences, such as rain, snow, lightning storms, swaying bushes and free-roaming animals, while still providing reliable detection of real threats.


TOWER-20AM MCW features the revolutionary Octa-Quad™ technology which uses eight PIR sensors, as compared to only one sensor found in other outdoor detectors. Each sensor acts as a Quad detector to accurately determine whether an alarm is justified. In addition, to further increase reliability, TOWER-20AM MCW has a robust housing and patented anti-masking protection that can distinguish between masking spray, rain and sprinkler irrigation, providing an exceptionally high resistance to vandalism and masking.


When used with Visonic’s PowerMax® advanced home security system*, the TOWER-20AM MCW wireless outdoor detector provides a complete solution for the protection of the house, inside and out.


TOWER-20AM MCW Features:
Superior outdoor detection with virtually no false alarms
Fully wireless, ideal for difficult installations
Innovative Octa-Quad technology accurately determines whether motion is legitimate, minimizing false alarms while ensuring the effective detection of real threats
Vandal-resistant design, enabled by patented V-Slot® technology, delivers unprecedented resistance to environmental interference and vandalism
Obsidian Black Mirror™ technology provides extremely high immunity to white light
Adaptive, active IR provides complete anti-masking protection (patented)
Patented, market-leading elliptical optics provide a longer detection range along with excellent detection sensitivity and false alarm immunity
12m x 12m (40ft x 40ft) / 90o coverage with true creep zone down looking optics
Installer-selectable, anti-masking setup can provide Trouble/Masking event notification without triggering an alarm to suit specific installation needs*
Compatible with all types of PowerMax panels and MCR receivers
Complies with international standards and certifications in Europe and USA, as well as IP55 rating


* When connected to PowerMax, PowerMax+ or MCR-308 receiver, turn ON the switch in order to send masking alerts to the control panel.

MCR-308+(868MHZ) [0-3192-8], Visonic, 4 Channel Receiver, Expandable to 28 - Comes with Volt Free Outputs


MCR-308 is a superheterodyne receiver designed to convert a standard hard-wired control panel into a reliable fully supervised wireless system. It provides a cost-effective opportunity to realize all the benefits of Visonic wireless systems and devices. 


MCR-308 is compatible with all Visonic PowerCode and CodeSecure devices – including hand-held and portable units, window/door transmitters and a variety of detectors and other devices. The MCR-308 has 4 zones, each accommodating up to 4 transmitter devices. It is easily expanded using up to three MCX-8 zone expanders, for a total of 28 zones and 112 wireless devices in a single system. Dry contact outputs can be provided, using the RL-8 relay module that converts 8 open collector outputs to dry contact outputs. 


MCR-308 is designed for wireless alarm, emergency and arm/disarm applications as well as for remote control applications. It is easy to install and program utilizing a unique "Easy Learn" technique for transmitter enrolment. It provides all the features that professionals require, including four additional outputs for low battery reporting, tamper protection, RF signal jamming and transmitter inactivity indication. 


When used with CodeSecure devices, the MCR-308 implements a rolling code encryption algorithm to prevent "code grabbing" by potential intruders trying to defeat the security system.


This highly reliable and versatile receiver is available in several optional frequencies in compliance with European, U.S. and other international standards, and is approved for use by local authorities in most countries.
