Qolsys QS7121-840 Hardwired 16:


The Qolsys QS7121-840 IQ Hardwire 16 is the perfect device to allow hardwired systems to leverage the powerful IQ Panel. This ground-breaking QS7121-840 translator allows up to 16 hardwired devices to be "taken over" from any existing control panel. The QS7121-840 is a "problem solver" that allows a seamless use of existing security system features (e.g. sirens, contacts, motion detectors, glassbreak detectors) with no additional equipment needed. The IQ Hardwire QS7121-840 automatic EOL (end-of-line) resistor learning spans from 1k-10k oHms ending the hours of wire splicing you'd normally encounter in an existing system. With a backup battery recharging circuit, 500 amp power supply and siren relay it's ideal for new construction as well. Please note, this hardwired translator is not for use with life safety devices, such as smoke or carbon monoxide (CO) detectors.
