What is UL 357?

The Introduction to UL 357

UL 357 is a technical standard that pertains specifically to batteries used in burglary alarm systems. It sets forth the requirements for the construction, performance, and operation of these batteries, ensuring their safety and reliability.

UL 357 aims to prevent incidents such as battery failures or malfunctions that could compromise the functioning of security systems. It is crucial for manufacturers, installers, and users of burglary alarm systems to be aware of and comply with this standard to maintain the optimum performance of their systems.

The Scope and Requirements of UL 357

UL 357 covers a wide range of aspects related to batteries used in burglary alarm systems. These include, but are not limited to, the battery's compatibility with alarm control panels, its design and construction, its performance characteristics, and its installation requirements.

The standard requires batteries to be tested under various conditions, including different temperature levels, fluctuating electrical loads, and extended periods of standby mode. It also specifies the minimum capacity and voltage requirements for batteries to ensure they meet the demands of a burglary alarm system during power outages or emergencies.

The Importance of Compliance with UL 357

Compliance with UL 357 is of utmost importance to protect against potential hazards arising from faulty batteries in burglary alarm systems.

By adhering to this standard, manufacturers can ensure that their batteries are designed and constructed to withstand critical situations without malfunctioning. Installers and users, on the other hand, can have confidence in the reliability and effectiveness of the burglary alarm systems when powered by UL 357 compliant batteries.

Conclusion

UL 357 is a technical standard that sets forth the requirements for batteries used in burglary alarm systems. It aims to ensure the safety and reliability of these batteries, preventing incidents that could compromise the functioning of security systems.

By complying with UL 357, manufacturers, installers, and users can have peace of mind knowing that their batteries meet the necessary standards and will perform as intended during power outages or emergencies.
