RISCO Group has added wireless accessories and modules to its WisDom wireless security system. The accessories include wireless shock, wireless flood, two buttons panic keyfob, advanced GSM/GPRS module (AGM), and wireless external and internal sounders. The two-way wireless external and internal sounders are battery-powered with no local AC power required, and have an expected three-year battery lifetime. Remote control via upload/download includes sounder volume control, strobe flashing speed, arm/disarm squawk and supervision time window. The AGM provides primary or backup cellular communication for reporting to central stations together with SMS or e-mail messages. The shock detector is based on the company’s wired ShockTec detection technology, with gross attack detection and tri-color LED for reliable calibration. The flood detector provides an alarm in case of flooding above the sensor level.
