The EV-H2-A1R is an analogue addressable heat detector designed for use in Nittan's Evolution analogue addressable fire detection systems. It serves as a backward-compatible replacement for the earlier EV-H-A1R model, offering enhanced features and performance.
Key Features:
Heat Category A1R: Suitable for environments with normal temperature conditions.
Backward Compatibility: Compatible with both the EV-H-A1R and EV-H-CS models, facilitating seamless upgrades.
Evolution FSK Protocol: Utilizes Nittan's Frequency Shift Keying (FSK) protocol for reliable communication within the system.
EEPROM Addressing: Addressed using a programmer, allowing for flexible configuration.
Omniview 360° LED Indicator: Provides clear visual indication of the detector's status from all angles.
Operating Voltage: 20–38 V DC
Quiescent Current: Approximately 300 µA
Alarm Current: Approximately 6.0 mA (with LED on)
Standards Compliance: Compliant with EN 54-5:2017 / A1:2018 standards
