Small, low profile design blends with any environment Description 2M-PDC Series self-diagnostic, two-wire smoke detectors are the industry's first conventional direct-wire smoke detectors with advanced features such as remote maintenance reporting, self diagnostics, drift compensation, and multi-criteria sampling. Self diagnostics. All 2M-PD detectors continually monitor their own sensitivity and operational status. The on-board LED provides a visual indication if the detector drifts out of its prescribed sensitivity range or fails internal diagnostics. This meets NFPA 72 field sensitivity testing requirements without the need for external mete/so Additional diagnostic information is retrieved by applying a magnet near the detector's integral reed switch. This initiates a self-diagnostic routine and indicates, by means of coded flashes of its LED, the sensitivity level and operational status ofthe detector. Drift compensation. Built-in drift compensation dramatically increases the periods between cleaning. This feature allows the detector to automatically adjust its sensitivity over time as it becomes dirty, which can effectively double the time between detector c1eanings. Field-replaceable optical chamber. Detector cleaning is ex- tremely simple with the 2M-PD's patented field-replaceable optical chamber. To clean the detector simply remove it's cover, pop out the dirty chamber, snap in a clean one, and replace the cover. Remote maintenance reporting. 2M-PDC detectors include the optional CleanMel!> feature, which automatically reports back to the control panel and central station when dirt buildup increases the risk of false alarm or when the detector fails other internal diagnostics. A separate CleanMel!> interpreter module relays this information from up to 20 detectors to the control panel (see catalog sheet 85001-0383). Multi-criteria sampling. The 2M-PDH combination photoelectric smoke detector/fixed rate-of-rise heat detector includes fast response algorithms for quick response to both flaming and smoldering fires. Fast response algorithms allow the heat sensors to work intelligently with the photoelectric smoke sensor. When the heat sensor detects a rise in temperature of more than 15 degrees per minute, the sensitivity of the photoelectric sensor automatically increases, allowing it to detect smaller particles of combustion much more rapidly than it would acting on its own. Application The 2M-PD is ideal for both retrofit applications and new installa- tions alike. It is particularly well-suited for installations where detector reliability is essential, but where intelligent analog devices, such as EST's Signature Series, may not be appropriate or feasible. The 2M-PD, with its replaceable optical chamber is equally well-suited to dusty environments where detectors require frequent cleaning. Two-wire 2M-PD detectors feature a field-selectable voltage range of either 6-12 Vdc or 12-24 Vdc. This voltage range is the widest available and makes the 2M-PDC ideal for dedicated life safety applications, as well as combination burglary/fire installa- tions.
