Information About D355PL
The D355PL is part of Honeywell’s InnovairFlex series, featuring a pivoting housing that supports both square and rectangular footprints for mounting on round or rectangular ducts. It uses photoelectric sensing technology to detect smoke particles and trigger alarms before hazardous conditions escalate. The unit supports air velocities from 100 to 4,000 ft/min, temperatures from -4 to 158°F, and humidity levels up to 95% RH non-condensing, ensuring performance in diverse environmental conditions. It is compatible with multiple remote test and indicator devices, includes a tamper-resistant sensor cover, and offers simplified wiring and installation with conduit knockouts and ample internal space.
Key Features:
-
Advanced photoelectric detection method: Utilizes a highly sensitive photoelectric sensing chamber to identify the presence of visible smoke particles at early stages, allowing for timely response to potential fire hazards in duct systems.
-
Versatile InnovairFlex housing: Features a pivoting design that supports both square and rectangular duct mounting, enabling installation on round or rectangular ducts without the need for additional adapters.
-
Wide environmental operating range: Maintains reliable operation from -4 to 158°F (-20 to 70°C) and in humidity levels up to 95% non-condensing, ensuring dependable performance in both cold and hot air handling environments.
-
Broad airflow compatibility: Designed to function effectively in duct air velocities ranging from 100 to 4,000 ft/min (0.5 to 20.3 m/s), accommodating a variety of HVAC system configurations.
-
Tamper-resistant safety feature: Equipped with a sensor cover tamper switch that sends a trouble signal if the cover is removed or improperly installed, ensuring system integrity and compliance with safety codes.
-
Comprehensive accessory support: Fully compatible with remote test stations, annunciators, and additional modules such as RA400Z, RTS451, RTS451KEY, and RTS151KEY for flexible system integration.
-
Simplified installation and wiring: Includes a 3/4-inch conduit knockout and ample internal space for straightforward wiring, reducing installation time and labor costs.
-
Service-friendly pluggable sensor head: Allows for quick removal and replacement of the sensing element without dismantling the entire detector housing, simplifying maintenance procedures.
The D355PL delivers the reliability and precision required for detecting smoke in demanding HVAC duct applications, ensuring early warning and system safety across a wide range of operating conditions.
