5. Introduction, Product Features and Specifications
Introduction
The Interlogix SDX-135Z supervised photoelectric smoke detector with heat and freeze sensors is a
self-diagnostic Learn Mode detector 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 SDX-135Z uses a 319.5MHz transmitter for communication to the control panel and a 915MHz
transceiver for interconnection communication between networked detectors. Up to 24 detectors can
be a part of the same interconnected network. The dual transmitter design ensures interconnection
integrity is maintained independent of control panel status. Because of this unique design the SDX-
135Z is multi-listed to UL217, UL268, and ULC-S531 requirements.
The SDX-135Z wireless smoke detector with heat and freeze sensor is compatible with Simon XTi-5
and Advisor One Interlogix Learn Mode panels. Refer to control system / panel installation instruc-
tions for compatible panel information.
The SDX-135Z uses 10-year sealed-in lithium batteries ensuring continuous operation over the 10
year life of the detector. This eliminates worry about battery removal or unauthorized deactivation
of the detector. The self-activation feature activates the detector when attached to the mounting
bracket. At the end of detector life, the unit will chirp and send communication back to control panel,
indicating the detector is in need of replacement (see Troubleshooting Guide).
To help identify the date to replace the detector, a label has been affixed to the side of the detector.
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 detector.
