Fire alarm devices must be installed and tested by qualified personnel in line with NFPA 72, local codes and the manufacturer's installation instructions. Please confirm that the 4WTR-B is compatible with your fire alarm control panel, wiring, voltage, mounting and finish before ordering. Contact us with the models of your existing devices if you need help checking compatibility.

Good to know: Operating temperature range is 32-100 °F (0-37.8 deg C) and operating relative humidity is 0-95%, so check that your install location falls within those limits.
