Enviromental Strength
-
Temperature Tolerance: Operates reliably from 32°F to 120°F (0°C to 49°C) in indoor fire alarm panels.
-
Humidity Resistance: Functions in 10% to 93% relative humidity, non-condensing, suitable for damp environments.
-
High Noise Immunity: Built-in EMF/RF rejection prevents false activations from electrical interference.
-
Heat-Resistant Plastic: Off-white face plate withstands moderate heat without deformation.
-
SEMS Screws: Clamping plates with captive screws simplify wiring and reduce loose hardware in enclosures.
-
Wide LED Viewing Angle: Easily visible status indication from multiple angles for quick inspection.
