The Model DUAL-824 24-Channel, 8-Loop Supervised Wireless/ Hardwire Security Panel is a hybrid alarm control that includes its own built-in superheterodyne receiver with a measured range of 1, 500 feet. Because the receiver is located inside the control panel cabinet, installers do not have to take the time to find a separate place to mount it. User controls for the DUAL-824 are centralized on an easy-to-read, backlighted, full-function Model DUAL-824KP keypad with numeric indicators for each of 24 supervised wireless sensor zones and up to eight hardwire loops. The DUAL 824 supports the addition of a second hardwire keypad. A built-in speaker generates alert and alarm zones. The DUAL-824 panel is housed in a high-impact plastic box, with room for a rechargeable backup battery. The DUAL-824 has six operating modes and can be configured for one-button operation, for eight user codes (including duress).
