A UL fire alarm system is a fire system that has been installed to Underwriters Laboratories specifications and is certified by that same group. The system is inspected by a UL certified inspector on a regular basis and the system must at all times adhere to the UL standard. Any changes or modifications to the system must be UL approved.
All of the alarm equipment must be UL certified as well. If the fire system is monitored by a Central Station, the Central Station must also meet the same stringent requirements in order to monitor the signals. The Central Station is also inspected by a UL inspector on a regular basis.

What does UL mean?
UL stands for Underwriters Laboratories, a non-profit organisation. Basically what they do is test different parts of products (AC Cord, microchips etc) and see if they are susceptible to catching on fire. UL certification does not guarantee that a product will function 100% properly, but they put their stamp of approval on items that are known not to catch fire during normal usage.

Not necessarily ... It depends on the product and the safety standards involved. UL approved simply means that the testing agencies Underwriters Laboratories (UL) or Underwriters Laboratories Canada (ULC) tested the product against safety standards. Underwriters Laboratories tests all sorts of products for all sorts of safety hazards. Presumably, if fire is a safety concern for the specific product tested, the approval would mean that the product met some sort of fire resistance standards.

How do yo turn off the alarm and chime on unlisted watch UL 1132 A126?
Idk about a UL 1132 A126, but on my UL 1138, all you have to do is the following: 1. Make sure you're on the regular time mode. 2. Hold down the reset button. 3. While holding the reset button down, press the start/stop button once. You should hear a beep, indicating the alarm has switched from on to off. Also, the small alarm icon under the digits should have disappeared.
