The IQ Hardwire 16 is the perfect device to allow hardwired systems to leverage the powerful IQ Panel. The IQ Hardwire 16′s 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. Note: Not for use with life safety devices, such as Smoke or CO detectors. Requires Qolsys IQ Panel RFPIC Version 7 or higher.
