Tyco Chrome Horizontal Sidewall Cover Plate (139F, 3-5/16″)

Tyco Horizontal Sidewall Cover Plate is a quick-acting cover built to increase aesthetic appeal while reducing the probability of objects being hung from the sprinkler. Part number 56-396-9-135 is Tyco’s chrome, domed plate for CHEC 8.0K extended coverage sprinklers with a sprinkler identification number (SIN) of TY4332.

This cover plate activates at a temperature of 139F (59C), about 20F (6.7C) cooler than the activation temperature of the compatible sprinkler head. This ensures that the cover plate will detach early enough to allow the sprinkler head to activate on time.

Will this fire sprinkler cover plate fit my sprinkler head?

Sprinkler Identification Numbers (SIN) that are compatible with this 3 5/16″ Tyco Horizontal Sidewall Cover Plate include:

  • TY4332

When installed properly, there should be a slight nominal air gap (3/32″ or 2.4mm) between the cover plate and the wall to allow heat flow from a fire to pass below and above the cover plate. This will help ensure the appropriate release of the cover plate in case of a fire.

What precautions should I take when installing Tyco’s white HSW fire sprinkler cover plate?

Cover plates should never be painted – the chemical properties of paint will tamper with the activation temperature of the fire sprinkler cover plate, and possibly render it unreliable. This could impede the cover plate’s ability to detach, which may stop the fire sprinkler head from activating on time.

All modifications or replacements should be performed by a qualified professional. Do not attempt to conduct your own modifications or replacements unless approved by your local authority having jurisdiction (AHJ), Even low-impact collisions with a fire sprinkler head may break delicate components, leading to water damage or eventual malfunction.
