The Wheelock MT 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.
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.

1 For synchronization, use the SM or DSM modules with these control panels and set the synchronization module for 12 VDC operation. Use the MT 121575W appliances.
2 The D7022 can be used in either 12 VDC or 24 VDC mode, but the synchronization module must be set for the same operating voltage as the control panel. Use the appliances with the same voltage as the control panel setting.
3 When used with a D7039 Multiplex Expansion Module, the FPD-7024 and D7024 become addressable fire alarm control panels (FACPs).
4 For synchronization, use the SM or DSM modules with these control panels and set synchronization module for 24 VDC operation. Use the MT 241575W appliances.
