OVERVIEW
The Interlogix
®
SDX-135Z photoelectric smoke detector with heat

and freeze sensor features wireless connectivity, a 10-year sealed
battery and sensor life, a built-in sounder, diagnostic/status LED,
integrated fixed-temperature and rate-of-rise heat sensor, and a
separate enrollment pre-freeze condition sensor.
The SDX-135Z uses a 319.5MHz transmitter to communicate with

the control panel and a 915MHz transmitter for communication
between networked detectors. Up to 24 detectors can be used in

the interconnected network. The dual transmitter design ensures

that interconnection integrity is maintained, independent of control
panel status. This unique design allows the SDX-135Z to conform

to UL 217 and UL268 requirements.
The SDX-135Z has a 10-year, sealed-in lithium battery, ensuring
continuous operation over the life of the detector. A self-activation
feature activates the detector when attached to the mounting
bracket. At the end of detector’s life, the unit will chirp and will
notify the control panel, indicating that the detector is in need of
replacement. A simple tool, such as a screwdriver, can be used

to deactivate the unit, stopping the chirp and making the unit

safe for disposal.
In addition, the SDX-135Z photoelectric smoke detector continually
monitors operational status and provides a visual trouble indication

if it drifts out of the sensitivity range or fails internal diagnostics.
