Simplex

Simplex, now part of Johnson Controls, is one of the most widely installed fire alarm brands in North America. Simplex systems are found in hospitals, universities, airports, high rises and industrial plants, and they are maintained for decades rather than replaced. That long service life is exactly why the parts are hard to find, and it is what this collection is aimed at.

With well over a thousand Simplex line items in stock, we cover:

• Simplex smoke detectors and sensors - photoelectric, heat, combination photoelectric and heat, and carbon monoxide sensors, plus replacement cartridges
• Sensor bases, including standard, sounder and relay bases
• Duct detectors, duct housings and duct covers
• Addressable modules - individual addressable modules, zone adapter modules, relay modules and NAC extenders
• Single and double action pull stations, break rods and station keys
• Horns, strobes, horn strobes and speaker strobes, wall and ceiling mount
• Device covers, cover plates and trim in red and white

Much of what we hold is discontinued or superseded Simplex stock kept specifically for existing installations. If a part is not listed, send the number through our quote page.
