The PAD300-PCD from Potter is a listed analog addressable combination photoelectric/CO detector compatible with fire alarm control panels that utilize the Potter Addressable Device (PAD) protocol. The CO sensing portion utilizes a proven electrochemical sensor for accurate detection of CO gas for life safety applications. The photoelectric detector complies with UL 268 7th edition enhanced smoke sensitivity tests. It has a wide sensitivity range of 1.1 to 3.5% per foot, and features drift compensation with built in dirty detector warning. The detector and the control panel communicate over a proven and robust digital communication path and the system analyzes the information at the particular device. The total polling speed is less than five (5) seconds, well under the UL requirements. The detector is compatible with any of the PAD300 series detector bases and simply twists on. The PAD300-PCD is addressed using DIP switches in the rear of the detector and can be easily programmed in the field without special tools. Features: Photoelectric Smoke Detection compliant with UL 268 7th Edition Carbon Monoxide (CO) detection compliant with UL 2075 10 year Carbon Monoxide detection lifespan with built in end of life indication Walk Test mode allows for fast easy validation of CO sensor operation Low profile, less than 2 inches with the base Wide selectable sensitivity range of 1.1 to 3.5%/foot Detector communicates sensitivity to control panel Optional locking tab to prevent unwanted removal Simple DIP switch address setting, no programming tool required LED Alarm Indicator Product includes 5-year warranty UUKL Listed for Smoke Control Magnetic Test Switch
