N45 Additional Output

The Additional Outputs module is a dedicated expansion unit designed to increase the signaling capacity of Honeywell’s DTS/LHD N45 linear heat detection system by providing 44 additional dry‑contact relay outputs. As the base detector includes 10 relays and can be expanded up to 98, this module enables seamless scalability for large or complex fire detection architectures. It integrates smoothly with the DTS system’s extensive zoning capability—up to 2000 alarm zones per channel—allowing precise transmission of alarms, pre‑alarms, faults, and system conditions to fire panels, BMS platforms, or external control systems. Engineered for industrial reliability, it supports all DTS alarm types, including fixed temperature thresholds, rate‑of‑rise detection, adaptive temperature monitoring, and cable fault indication.

• Its robust design makes it suitable for demanding environments such as tunnels, power plants, conveyor systems, and storage facilities. By expanding output capacity without requiring additional detectors, the module delivers a cost‑effective, flexible, and scalable solution that enhances system integration, improves operational awareness, and supports detailed zone‑specific monitoring across large infrastructures.
