PRODUCT OVERVIEW: The GTHDT series of industrial emergency lighting units are designed to be durable, dependable and easy to install. The fully gasketed NEMA 4x rated PVC housing can be used in most damp, wet, and hose down areas. The GTHDT has been designed with the PulseGuard pulse switching charger. The PulseGuard offers superior performance & energy efficiency versus conventional constant voltage chargers. Traditional top mounted Par36 style heads are standard.

CONSTRUCTION: The GTHDT series is constructed with a durable NEMA 4x rated PVC cabinet. Industrial gray finish is standard. Emergency lighting heads are molded from high impact thermoplastic, Par36 style heads are standard. Integrated mounting feet ensure proper and secure installation. The front access panel is hinged to allow for trouble free installation and maintenance. External test switch and monitor LED are standard.

ILLUMINATION: The GTHDT series is normally supplied with two top mounted Par36 style 9w heads. Lamp head styles are constructed of high impact thermoplastic. Par36 style food-prep approved lenses are also available when ordering. 6V TUNGSTEN: standard: 9w, (H) halogen: 8w, 10w, 12w, 20w 6V SEALED BEAM: (SB) standard: 9w, 12w, 18w (SBH) halogen: 12w, 20w 12V TUNGSTEN: standard: 9w, 18w (H) halogen: 8w, 12w, 20w, *35w, (*LR only) 12V SEALED BEAM: (SB) standard: 12w, 18w (SBH) halogen: 8w

BATTERY TECHNOLOGY: The GTHDT series is designed with a maintenance free, sealed valve regulated lead acid battery that provides a minimum emergency duration of 90 minutes (for the listed rating). Recharge time of the battery is twenty-four hours. The maximum working temperature is 50 C.

INSTALLATION: The GTHDT series is suitable for surface wall mounting. Suitable for NEMA 4x required installations. Four integrated mounting feet ensure proper, secure and accurate wall or ceiling installation.

ELECTRICAL SPECIFICATIONS: Charger Type: Solid state charging circuitry
Utility Input: 120/277VAC, 60 Hz. Power Consumption: 68 watts (maximum)
Temperature Range: Max 50 C
Recharge Duty Cycle: 24 hours
Load Transfer: All models utilize a solid state transfer circuit for 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. Short Circuit Protection: On units with solid state transfer, output protection is 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 AC voltage sags below 80% of nominal.

CODE COMPLIANCE: All models are UL924 Listed and meet NFPA 101 Life Safety Code, NEC, OSHA, BOCA, state and local Codes.
