The Wheelock MT Mult candela Electronic Appliances are audible and visual alarm indicating devices engineered to comply with temporal pattern specifications without requiring an additional code mechanism. They have a selection of eight tone patterns, two sound output levels, and four light intensities (15 cd, 30 cd, 75 cd, or 110 cd). The temporal (Code 3) horn and tone patterns meet ANSI/ NFPA/ISO requirements for standard emergency evacuation signaling.
The extended temperature range satisfies all severe weather outdoor applications. The option to silence the audible signal allows emergency personnel to communicate while maintaining the visual alarm condition, a requirement in some jurisdictions.
