Wheelock MT Series Fixed-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 a strobe listed at 15 cd that provides 75 cd of light intensity on axis. The temporal (Code-3) horn and tone patterns meet ANSI/NFPA/ISO requirements for standard emergency evacuation signaling.
