1. Heat Alarm: What To Do When the Alarm Sounds
Heat alarm pattern is three long beeps, a 1.5 second pause, and three long beeps repeating.
The red LED blinks in time with alarm pattern.
•Alert small children in the home as well as anyone else that might have difficulty recognizing the
importance of the alarm sounding or that might have difficulty leaving the area without help.
•Leave immediately by your escape plan. Every second counts, so don’t waste time getting dressed or
picking up valuables.
•In leaving, don’t open any inside door without first feeling its surface. If hot, or if you see smoke seeping
through cracks, don’t open that door! Instead, use your alternate exit. If the inside of the door is cool,
place your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke rush in.
•If the escape route requires you to go through smoke, stay close to the floor where the air is cleaner.
Crawl if necessary, and breathe shallowly through a cloth, wet if possible.
•Once outside, go to your selected meeting place and make sure everyone is there.
•Call the fire department from your cell phone outside, or from your neighbor’s home-not from yours!
•Don’t return to your home until the fire officials say that it is all right to do so.
•There are situations where an alarm may not be effective to protect against fire as stated in the NFPA
Standard 72. For instance:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as gasoline
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

4. Introduction, Product Features and Specifications
Introduction
The HDX-135Z-433 supervised heat alarm with freeze sensor is a self-diagnostic alarm with wireless
interconnection, 10-yr sealed battery and sensor life, built-in sounder, diagnostic/status LED,
integrated fixed temperature and rate-of-rise heat sensor and a pre-freeze condition indicator.
The HDX-135Z-433 uses a 918MHz transceiver for interconnection communication between
networked alarms. Up to 24 alarms can be a part of the same interconnected network.
The HDX-135Z-433 uses 10-year sealed-in lithium batteries ensuring continuous operation over the
10 year life of the alarm. This eliminates worry about battery removal or unauthorized deactivation of
the alarm. The self-activation feature activates the alarm when attached to the mounting bracket. At
the end of alarm life, the unit will chirp, indicating the alarm is in need of replacement (see
Troubleshooting Guide).
To help identify the date to replace the alarm, a label has been affixed to the side of the alarm. Write
the “Install date” in the space provided, and then write in the “Replace by” date (10 years from initial
power up) in permanent marker on the label prior to installing the alarm.
