The Model SXR-64A is a 64-channel, 8-zone, supervised wireless receiver/annunciator designed for use in residential or commercial security systems. Housed in a rugged metal enclosure with a high-gain receiver, the SXR-64A connects to a hardwired alarm control panel adding wireless capability to the panel. The unit's eight alarm zones and four supervisory outputs provide a flexible interface. Any or all of the zones can be used. The SXR-64A receives signals from a variety of security transmitters then processes, displays and transfers the signal to the hardwired alarm control panel. Six unique conditions for each transmitter can be shown on the unitís display. Conditions such as Open Portal, Transmitter Low Battery, Transmitter Tamper and First Alarm In show the status of each transmitter in the system. Valuable features such as Alarm Memory and Transmitter Status allow for quick system diagnosis and troubleshooting. All of the solid state zone outputs can be either normally open or normally closed electrical configuration and can switch up to 100 mA @ 24 VDC. An easy programming interface using four pushbuttons lets the installer quickly setup the system. The UP, DOWN, ADVANCE and MEMORY buttons are located inside the receiver case and are used for transmitter and system programming. An on-board, high-gain, superheterodyne radio receiver gives the SXR-64A excellent reception. The MODE indicator shows RF activity. The local whip antenna (supplied) or remote external antenna (Model EXA-1000) connects to the receiver through a standard type F connector. The SXR-64A decodes Linearís SX, S1, and MegaCode format transmitters. The SXR-64A can be used as a direct replacement for Linearís SS-32, SSR-32, & SXR-64 receivers with an installation bonus of being able to use up to 64 transmitters in the system. Power for the SXR-64A is provided from the alarm control panel. To control the alarm memory, reset tamper and status alert conditions, an armed input on the receiver connects to an armed output from the control panel.
