The Cooper ULMCOM intelligent addressable micro single channel output module represents a high-specification lifecycle solution engineered to deliver smart, panel-driven automated auxiliary peripheral control. Specifically optimized for complex integration layouts inside large-scale high-rises, secure corporate environments, and active manufacturing logistics facilities, this ultra-compact module provides seamless electronic interfacing between your fire command network and external critical structural components.
By delivering native software-driven soft-addressing functionality, the high-performance Cooper ULMCOM eliminates traditional technical configuration bottlenecks. The master panel automatically discovers, numbers, and maps the device during initialization loops, completely removing the setup time and configuration mistakes associated with older mechanical binary dip-switches.
The Cooper ULMCOM houses a highly responsive set of dry, non-latching changeover relay contacts optimized for switching low-voltage control circuits. This makes it an ideal engineering match for automating industrial facility shutdowns, executing high-priority air-handling HVAC fan cuts, managing localized elevator recalls, and unlocking electromagnetic emergency exit fire door closures during an active alert sequence.
Every component of the compact Cooper ULMCOM is designed for long-term project reliability. Outfitted with an integrated short circuit line isolator, the module isolates wire pinch damage locally, keeping adjacent branch hardware fully online. Its miniature form factor fits comfortably into external machinery cabinets or a shared, space-saving micro module cluster box, giving system designers maximum flexibility when planning distributed building architectures.

Q1: What does “non-latching contacts” mean for the operation of the Cooper ULMCOM?
A: Non-latching contacts follow the active state of the fire panel directly. The relay changes positions immediately upon receiving an output command from the panel, and returns automatically to its normal standby position as soon as the panel goes through a system reset sequence.
Q2: Can I use this micro output module to switch primary 230V AC mains electrical lines?
A: No, absolutely not. The dry contacts are rated strictly for low-voltage signaling gear (up to 30V DC at 1A max). For switching high-voltage plant networks or 230V AC mechanical locks, you must use the specialized, mains-rated ULCMIO353 relay interface unit.
Q3: What is the operational difference between the ULMCOM and the optional ULMCOM-S variant?
A: While the default model maps to the panel as a general input/output control module, the ULMCOM-S variant configures specifically as an addressable sounder. The sounder variant drops on the network when the panel executes an alarm silence command, allowing up to 60 units per loop layout.
Q4: Are the output contacts monitored by the signaling data circuit for open or short wire faults?
A: The data loop wiring input going into the micro module is fully supervised for open, short, and ground faults via its built-in short circuit isolator. However, the auxiliary volt-free relay contacts outputting to external equipment are unmonitored and must be tied to a power-limited electrical supply.
Q5: How many individual single-channel micro units can be clustered in one spot?
A: Thanks to their highly minimized spatial footprints, technicians can cluster up to three individual micro output modules or micro input units neatly inside a single, empty ULBU micro module surface box housing.
