HySecurity has made a change to the Hy5B that requires a new part number. Effective immediately please order MX4621 rather than MX4125. The new detectors are marked “Hy5B 2.0”.
HySecurity’s new SmartCNX controller will operate at a lower voltage than Smart Touch and Smart DC controllers. To be compatible, the Hy5B power circuit needed to be updated. Also changed are the terminals for loop wires to a spring lever type for easier installations. All the features and capabilities of Hy5B remain unchanged. There is also no change in price.
MX4125 is not compatible with the coming SmartCNX controller. MX4621 is compatible with all new and existing Smart Touch, Smart DC, and SmartCNX controllers.
