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 LEd’s for 360° indication of status. In standby condition the power LED’s flash Green. In an alarm condition the LEd’s 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° ± 7.5°F). If the heat rise is greater than 12°/minute the LE-dCd will alarm immediately giving an early warning signal and latching the Red alarm LEd’s on.
The LE-ASB Analog Sounder Base is designed for use with Lifeco analog style sensors models LE-ALG-V, LE-ALK-V, LE-ALK-V2 LE-AIE-EA, and LE-ATG-EA. Each addressable base is to be connected to a Lifeco dCP Signaling Line Circuit (SLC). The LE-ASB provides an audible alarm in the immediate vicinity. Typical applications are use in hotels, apartments, and hospitals. The LEASB has a highly configurable programming algorithm that allows the user to setup groups of bases for synchronization of modulation tones. Each device has 16 states that are programmed with the desired output pattern to be used (e.g., “Temporal” or “March”) for each state.
