The PowerMaster-30 is an intrusion alarm system based on Visonic’s patent-pending PowerG wireless technology designed for large residential premises and mid-size businesses. The system’s PowerG network uses two-way, low-power frequency hopping spread spectrum (FHSS) technology to ensure that each transmission arrives uninterrupted at its destination. PowerMaster-30 employs advanced radio and diversity antenna technologies that, when combined with FHSS and synchronized TDMA communication, result in a transmission range of up to 2,000 m/6,000 ft. PowerMaster-30 supports up to 127 devices/peripherals with 64 zones and 48 users.
