50 ohms maximum per length of Style 6 & 7 loops.For a twisted-unshielded pair, 12 AWG (3.1 mm²) to 18 AWG (0.78 mm²): LCM-320 Maximum loop length: The maximum wiring distance of an SLC using 12 AWG (3.1 mm²) twisted-pair wire is 12,500 feet (3810 m) per channel. Permits multiple loops in small enclosure.Very simple installation - plug-in style.Built-in degraded mode increases survivability.Up to 12,500 feet (3,810 m) on a Class B (Style 4) SLC loop (twisted-unshielded).The LEM-320 module is used to expand the NFS-640/NFS2-640 to a second loop, and to expand each LCM-320 used on the NFS-3030/NFS2-3030 - each NFS-3030/NFS2-3030 LCM-320 supports an expansion LEM-320.
The ONYX® Series NFS-640/NFS2-640 supports one LEM-320 the NFS-3030/NFS2-3030 supports up to five LCM320s and five LEM-320s. The LCM-320 Notifier Loop Control Module and the LEM-320 Notifier Loop Expander Module provide NOTIFIER’s ONYX® Series of Fire Alarm Control Panels (FACPs) with Signaling Line Circuits (SLCs). Production Capacity: as per requirement.Digital filters remove signal patterns that are not typical of fires, thus virtually eliminating unwanted alarms. To make an alarm decision, the detector’s on-board microprocessor measures and analyzes smoke and heat sensor readings and compares this information to historical data. Like all Signature Series detectors, the SIGA-PHD gathers analog information from its sensing elements and converts this data into digital signals. Together these sensors efficiently detect smoldering fires, as well as fast flaming fires. The SIGA-PHD provides an optical smoke sensor and a rate-of-rise heat sensor with a fixed temperature setting. Continuous self-diagnostics ensures reliability over the long-haul, while environmental compensation helps reduce maintenance costs. The Signature Series SIGA-PHD detector brings advanced multisensor technology to a practical design that increases efficiency, saves installation time, cuts costs, and extends life safety and property protection capabilities. Fuse: 8 amps, 250 V, 5 x 20 mm, Fast Acting, ceramic, p/n 12117.Providing auxiliary 24 VDC power 0.5 A and 5 VDC power 0.15 A.
The devices are managed by embedded software running complex algorithms that further improve resilience to false alarms and improve detection speed. The plug-in unit uses sophisticated processing circuitry that incorporates smoothing filters to help eliminate transient environmental noise conditions that can be the cause of unwanted alarms. This delivers improved responsiveness, reduced sensitivity changes caused by settling dust and reduced false alarms resulting from insect ingress and other debris.
The MI-PSE-S2 photoelectric smoke detector has a completely new detection chamber design, the result of many years of research and development.
