Chemetron Pre-Action Systems


Chemetron control panels and detection devices feature automatic and manual programming, systems status monitoring, and other advances for detection and release. There are three main categories for alarm systems: addressable, conventional and special detection.

Addressable Systems
Addressable systems, also called "intelligent" systems, enable each and every initiating device to have an individual address, or zone identifier. This is most beneficial when servicing a system. If a detector is faulty, the technician knows exactly which device is at fault. The addressable devices all connect to a single loop that runs through the premises.

MICRO SLX Control Panel
Intelligent, Addressable Fire Control Panel

The Chemetron Micro SLX Fire Alarm/Suppression Control Unit is a compact, multiplexed control unit suitable for either stand-alone or peer-to-peer networked applications. The Micro SLX advanced features handle the demanding operational requirements of fire extinguishing systems, and provide complex command and control capability for multiple suppression systems at the lowest total-installed cost.


Superior in performance than anything else in its class, the Micro SLX is designed to satisfy the market demand for a fully-featured control unit in a cost-effective package. The Chemetron Micro SLX can support the full line of extinguishing/suppression systems, from Low- and High-Pressure Carbon Dioxide, Clean Agents, and Water Mist.

Conventional Systems
Conventional systems are set with a certain number of zones that are hardwired to the control panel or zone expander. Smoke detectors must be run on a separate zone from pull stations, etc. There may be a dozen detectors in a single zone and if on is faulty, the technician is tasked with finding it. More cable is required because instead of having multiple devices wired into the same loop, a separate cable run for each type of device is required for these conventional systems.
Micro XLT and XLT lp Control Units
Suppression-Fire Alarm Control Panel

The Chemetron Micro XLT and XLT lp* Control Units are the most advanced conventional single hazard agent releasing systems available to the industry today.
