Interlogix SDX-135Z

The Interlogix SDX-135Z Wireless Interconnected Photoelectric Smoke Detector with Heat and Freeze serves as a valuable life-safety sensor for a home or business. This device allows for an interconnected network of up to 24 compatible smoke detector for added reliability and dependability.

As a smoke detector, the SDX-135Z relies on photoelectric technology to determine when smoke is present. When smoke enters the chamber, the internal light sensor will experience refraction. This will let the sensor know it needs to activate and alert the security system. The system can forward the alert to a central monitoring station for automatic emergency dispatch. The device also features an 85 dB temporal 3 and temporal 4 sounder and built-in status-indicating LED light.

In addition to smoke detection, the SDX-135Z also offers heat detection and freeze detection functions. Heat detection is the perfect supplement to smoke detection, as it can catch fires even if the smoke does not reach the sensor. Meanwhile, freeze detection can alert users before the pipes in their home freeze and cause serious damage. The heat sensor activates at 135°F or above, while the freeze sensor activates at 41°F or below.

One great feature of the SDX-135Z is the ability to create a network of up to 24 interconnected smoke detectors. With the device's dual transmitter design, interconnectivity is always reliably maintained. This occurs independently from the alarm panel in order to provide added insurance of proper function. The device has a 10-year lifespan and an internal 3V battery that cannot be replaced. At the end of its product life, the device will begin chirping to let the user know that replacement is needed.

The SDX-135Z is capable of sending out 319.5 MHz wireless signals for any alarm, tamper, maintenance and low-battery condition. The 319.5 MHz signal allows the device to work with Interlogix/GE Systems and Qolsys Systems with the legacy 319.5 MHz daughtercard. The device also includes its own mounting bracket for easy setup and installation. Make sure to place your system on test mode with the monitoring station and test the sensor after installation.

Read here to learn the difference between smoke detectors and smoke alarms. Photoelectric smoke detectors work with an alarm system, and when properly maintained and tested, can last for an indefinite period and do not automatically require replacement after a certain period of time like smoke alarms and CO detectors do.

Note: This product allows for an interconnected "one-go-all-go" network of up to 24 compatible devices. For more information, please see this document.

Note: This product uses separate and unique "TX ID" codes when enrolling into a compatible panel. One code is used for smoke/heat, and the other is used for freeze detection. There are labels on the outer packaging that provide these codes. This makes it possible to enroll the sensor for one function (i.e. either smoke/heat or freeze), while not enrolling the other function, if desired. Keep in mind that the sensor's internal sounder will still activate for smoke/heat even if that function is not enrolled with the panel. But its internal sounder will not activate for low-temperature detection. This makes it possible to use the sensor for only smoke/heat detection, while leaving freeze detection unused.
