The LE-DCD-135/-190 fixed temperature/rate-of-rise heat detectors are suited to detect in the presence of slow or fast rising temperatures due to burning combustibles. The construction of these models incorporate a thermistor heat element protected from damage by the built-in, durable plastic guard. These electronic heat detectors incorporate two power/alarm LEDs for 360 indication of status. In standby condition the power LEDs flash Green. In an alarm condition the LEDs latch on Red. The LE-DCD-135/-190 electronic heat detection circuitry performs the same function as a Mechanical Device but with Electronic Precision. If the heat rise is less than 12/minute the LE-DCD will not alarm until it reaches its alarm temperature (135 or 190 7.5F). If the heat rise is greater than 12/minute the DCD will alarm immediately giving an early warning signal and latchingthe Red alarm LEDs on.
The LIFECO LE-ALN-V Photoelectric Smoke Sensor is particularly suited to detecting optically dense smoke typical of fires involving materials such as soft furnishings, plastic, foam or other similar materials which tend to smoulder and produce large visible smoke particles. LIFECOs unique design allows fast response to flaming fires as well as smoldering fires while eliminating false alarms.

Description
The LIFECO LE-DH-98 Duct Smoke Detector provides early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial, Industrial and Residential applications. The LE-DH-98 is designed to prevent the recirculation of smoke in areas by the air handling systems, fans and blowers. Complete systems may be shut down in the event of smoke detection. The LIFECO LE-DH-98-I and the LE-DH-98-P operate on 115 VAC, 24 VAC and 24 VDC respectively and the LE-DH-98 operate on 230 VAC, 24 VAC and 24 VDC.
The LE-DH-98 is designed and built to meet all local requirements, as well as the NFPA regulations regarding duct smoke detectors. Output terminals are provided for remote accessories such as a horn, strobe, remote status indicators and reset key switches or push buttons
The LIFECO LE-SPC-24 Projected Beam Smoke Detector consists of an emitter and receiver. The projected beam smoke detector should be placed so that smoke generated by a fire will likely rise into the path of the beam. The receiver is constantly monitoring and measuring the intensity of the beam transmitted by the emitter. Should the smoke from a fire cause a decrease in the signal strength of a magnitude that exceeds the programmed obscuration setting, an alarm signal is generated. The LE-SPC-24 Projected Beam Smoke Detector can provide vital fire detection in applications where other types of detectors may not be able to respond quickly, or at all, to a fire condition
The LF-PE-4211 Conventional type Photoelectric Smoke Detector uses a specialized smoke chamber design, which could sense the presence of smoke particles produced by fast combustion or slow smoldering fire. Combining fire algorithms stored on its memory with the special three part design of the smoke chamber and given the photo-sensors viewing angle, the detector can effectively sense both white smoke and black smoke with virtually no false alarm.
