Duct Limit switch for apartments

The Firestat presents critical safety benefits when integrated into duct systems, primarily aiming to contain fire and smoke propagation during building fires. By strategically placing Firestat’s within HVAC ductwork, these devices monitor air temperature. Once the set temperature threshold is reached, the Firestat triggers, interrupting the airflow and halting the spread of fire and smoke throughout the building. Manual reset is then required to ensure comprehensive safety measures. Purchase your Firestat today to safeguard your property.

Firestat Limit Control Variations

1. Fixed Temperature Firestat: Pre-set at temperatures of 125°F, 165°F, or 200°F, with a standard 5-inch rod length.
2. Adjustable Temperature Firestat: Allows manual temperature adjustment within a range of 100°F to 250°F, offering flexibility. Available in three rod lengths: 5 inches, 7.5 inches, and 11 inches.

Both variants are manufactured in the USA, easy to install, and UL approved.

Firestat Safety Benefits for Apartment Complexes

Firestat Adjustable Duct Control

Apartment complexes stand to benefit significantly from Firestat installations. During a fire incident within an apartment, Firestats prevent the spread of fire and smoke to adjacent units or other areas of the building. This proactive measure greatly enhances the safety of residents and protects the property from extensive damage.

Role in HVAC Systems and Building Codes

Local and regional building codes often mandate the use of devices like Firestat’s in HVAC systems to regulate airflow within ducts. Particularly in multi-family dwellings sharing HVAC infrastructure, Firestat’s serve to contain smoke, minimizing its spread to multiple units.

High Limit Duct Controls, like Firestat’s, offer straightforward and economical solutions to safeguard homes and apartment complexes. These devices detect preset temperature limits and automatically halt connected systems, such as fan blowers or main HVAC units, upon activation. Manual intervention is necessary to reset the system, ensuring thorough safety protocols are followed.

CEMCO Duct Limit Switches

The Firestat Duct Fan and Limit Thermostat Switches operate using the same physics to ensure HVAC safety. A helix bi-metal element senses a rapid temperature change. When the temperature changes the bi-metal expands and triggers a snap action switch and either opens or closes a circuit. These switches are commonly installed in air ducts designed to shut down heating, air conditioning and ventilation equipment in apartment complexes and other multiple dwelling units when air temperature exceeds the set point.
