“HSM lets me relax and enjoy the bigger picture.”

When the HSM-installed smoke or heat detector is activated automatically, or manually at the touch of a button, an alarm sounds and a signal is sent to the HSM 24-hour UL Monitoring Center. UL approval means these stations are fully staffed around the clock with trained security professionals ready to handle any emergency. Our monitoring centers are equipped to operate at all times, even during power outages.
