The Acclimate 2251TMB photoelectric detector includes thermal detection at 135°F. It uses advanced onboard software to combine the signals from the photo and thermal elements to create a true multi-criteria detector that responds quickly to real fires while rejecting nuisance alarms.
This multi-function module combines two monitor inputs and two relay outputs into one device. The module is capable of Class B supervised wiring to the monitored devices. It also contains Form C relay contacts allowing the panel to switch the contacts on command. There is a dedicated LED on the module for each input and output. The control panel can use these bi-color LEDs to indicate normal, alarm and trouble conditions.
Jeffrey LaSalle has been a fire protection engineer and consultant since 1988. Throughout his career, LaSalle has worked in a variety of roles across many building and facility types, including cultural facilities such as museums. As founder of LaSalle Engineering, LLC, a fire and life safety consulting engineering firm specializing in fire protection and life safety engineering, code consulting, and construction administration, he services a variety of industries and clients that need to protect high-value or irreplaceable assets, including the Philadelphia Museum of Art and the Smithsonian Institution
i3 Series Smoke Detectors deliver intelligence, installation ease, and instant inspection for optimal performance and reduced costs. A plug-in design and Stop-Drop ‘N Lock™ mounting simplify installation. Smoothing algorithms and intelligent drift compensation minimize nuisance alarms. Accessories for remote sensitivity testing and remote maintenance signaling enable instant inspection.
Savvy fire and life safety designers advocate for the right systems for each large indoor venue, while respecting the sometimes conflicting goals and demands of others involved in the decision.
Jim Mickowski, an engineer with PSJ Engineering, has more than 25 years of experience in the design and installation of fire suppression systems. His experience ranges from working on stadiums, museums and office buildings to high-security, high-risk areas in correctional facilities and nuclear facilities where there is “no access allowed.”
As one of Seattle’s largest school campuses, Chief Sealth and its co-located facility Denny International Middle School are undergoing a complete renovation and rebuild.
Inmates will abuse any building component within reach. So how do you design a system to detect and protect while keeping it safe, too?
Many of us can relate to the logic that there’s no sense reinventing the wheel: Why start fire and life safety design from scratch when there are already so many tried-and-true procedures and examples from which to borrow?
Cut costs, speed installation, and improve aesthetics on emergency communications applications that require fire and emergency warnings by combining the functions of two to three devices on a single mounting plate and back box.
