PRODUCT OVERVIEW: The DTTW Series Architectural LED Emergency Light with normally on mode is the most efficient and longest lasting emergency light available today. The DTTW’s two powerful 5-watt LEDs produce an impressive 50-foot illumination distance. Eight different finishes are available including white, black, aluminum, and aged copper. The DTTW wall mounts to a standard 3-1/2” octagonal junction box. A Nickel Metal Hydride battery provides a minimum 120 minutes of reliable and maintenance-free operation when AC power is lost. Self-diagnostic testing and battery test switch are standard. UL 924 Listed and damp location rated.

CONSTRUCTION: Robust die cast and extruded aluminum housing. A full range of pleasing architecturally inspired finishes are available. Wall mount to standard 3-1/2” octagonal junction box.

ILLUMINATION: Illumination is provided by two 5 watt, white LEDs and an aluminum reflector. The lamp head assembly may be rotated in five-degree increments over a range of 60 degrees for ideal distribution along the egress path. DTTW will provide one foot-candle average illumination over a 50’ long path of egress. IES photometric data files are available.

BATTERY TECHNOLOGY: Maintenance-free sealed nickel metal hydride with 10-year life. Supplies 120 minutes of emergency power.

INSTALLATION: DTTW is designed to be wall mounted to a 3-1/2” octagonal junction box. The DTTW installs quick and easy using simple two-piece snap together construction. The backplate is provided with convenient keyhole slots for mounting and a tamperproofing option is available.

ELECTRICAL SPECIFICATIONS: Charger Type: Surge-protected, solid-state circuitry provides for a reliable charging system
Utility Input: 120/277VAC, 60 Hz.
Load Transfer: A solid state transfer circuit provides load connection.
Controls: Momentary test switch and LED AC-On indicator light
Safety Circuitry: AC Lockout: Prevents battery discharge prior to initial unit power-up saving installation time.
Low Voltage Battery Disconnect: Protects the battery from being severely damaged by deep discharge during prolonged power failures. DC Overload and Short Circuit Protection: Provided by a disconnect circuit that automatically resets itself when the fault condition is corrected. Brownout Protection: Automatically switches the unit to emergency mode when utility voltage is reduced to the point at which most fluorescent light fixtures would extinguish.

CODE COMPLIANCE: UL 924, UL damp location listing optional. NFPA 101, NEC, BOCA, OSHA and IBC illumination standards. Approved for use in the city of Chicago.
