The Wheelock MTWP Weatherproof Appliances are four wire appliances listed for indoor or outdoor use. They provide eight tone patterns, two sound output levels, and a strobe rated at 75 cd at -31°F (-35°C) and 180 cd at +77°F (+25°C). 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 strobe portion can be synchronized using the SM (single) or DSM (dual) Synchronization modules or a compatible control panel. The audible portion cannot be synchronized, but it can be connected to a coded fire alarm system.
Notice
These products are not suitable for hearing impaired applications.

1 For synchronization, use the SM or DSM modules with these control panels. The synchronization module must be set for 24 V operation. When used, the D7022 must be set for 24 VDC operation.
2 When used with a D7039 Multiplex Expansion Module, the FPD-7024 and D7024 become addressable fire alarm control panels (FACPs).
Mounting Considerations
Outdoor or Severe Environment Applications
Notice
Mount the 2475C models only on flat ceilings and mount the 2475W models only on flat walls.
For an outdoor application or a severe environment (NEMA 3R) application, mount these multitone appliances with an IOB Indoor or Outdoor Back Box on a flat wall or ceiling so the entire rear surface of the back box is covered. The drain holes in the back box must point toward the ground. The knockouts on the rear surface of the back box must remain intact.
The knockout hole on top of the back box is sized for a half-inch conduit and matching connector. Use a proper watertight conduit fitting.
Indoor Applications
For inside applications, mount these multitone appliances on the indicated back boxes for the indicated applications:

Indoor Retrofit Applications
Where an oversize electrical box is already installed, thsee multitone appliances can be installed with the RP R Retrofit Plate that measures 8 in. (20.3 cm) high by 5.875 in. (14.9 cm) wide.
Wiring
Notice
These strobe units are not recommended for use in coded or pulsed signaling circuits.
The input terminals accept wires with diameters between 18 AWG and 12 AWG (ISO 0.75 mm2 and 4 mm2).
