Apollo Series 65 CR 90C Rate of Rise Heat Detector

The Apollo Series 65 CR 90°C Rate of Rise Heat Detector (55000-132APO) is a specialized high-temperature sensor engineered for environments with extreme ambient conditions. As a Class CR device, it provides a crucial early warning by monitoring rapid temperature spikes while maintaining a very high fixed-temperature trigger point to prevent nuisance alarms in hot zones.High Temperature Limit:Features a fixed alarm threshold of 90°C, making it one of the most resilient detectors in the Series 65 range for high-heat applications.Rate-of-Rise Logic: Utilizes dual thermistors to detect a quick increase in temperature, ensuring a rapid response to fast-burning fires even before the static limit is reached.Industrial Grade: Designed to provide stable, dependable performance in harsh settings where steam, fumes, or high-density dust would compromise optical smoke detectors.Standard Mounting: Fully compatible with the Series 65 base range, allowing for a consistent and simple “twist-lock” installation across the entire system.The CR-class detector is the primary choice for industrial kitchens, laundry facilities with commercial dryers, and boiler rooms where high operating temperatures are a standard part of the environment. It offers contractors a robust solution for maintaining fire safety compliance in locations that demand extra thermal headroom.Explore the full Series 65 range for compatible products and accessories.Why buy from Direct Trade Supplies?Competitive trade pricing, fast UK delivery, and trusted products from leading brands.
