2251TEM
• ADM loop technology with
System Sensor/200 protocol
• Combination of optical and thermal
characteristics of fi re
• Two self-learning and three fi xed
sensitivity levels
• Thermal-only operation
• Constant r esponse sensitivity
• Function testable with magnet
Description
The addressable Multisensor 2251TEM uses the cation between the fi re detection control panel and the
scattered light principle as well as a separate thermal detector. That ensures a periodical functi
