Lawrence Doors

• Model No.Model PD

The Lawrence Model PD is a truly high performance rolling door… designed for 500, 000 cycles usage – and with an average operating speed of approximately 24 inches per second to open, 12 inches per second to close. PD High Performance Doors are ideal in very high usage or high speed applications for openings up to 20 ft. wide, 16 ft. high* (consult factory for larger sizes). Standard Door Features • Type 3 standard flat slats or Type 33 insulated slats* (R5) – available in galvanized steel, stainless steel, or aluminum • Delrin endblocks attached to slats to reduce friction • Scratch-Guards protection system to reduce finish wear and operating noise • Tubular bottom bar fabricated from aluminum extrusions • Guides fabricated from 14" steel shapes with replaceable UHMW wearstrips • Outer and inner guide are separately removable to provide easy access to curtain for inspection and service • Springless barrel design – minimum 8 58” diameter pipe and 1 12" shafts *Doors with insulated slats are limited to 14 ft. high Standard Safety Features • Monitored sensing edge to stop and reverse a closing door upon contact with an obstruction – rubber dual-chamber profile design with integral isolated conductive elastomer switches • Secondary monitored light curtain to stop and reverse a closing door upon sensing an obstruction in the opening. • If a sensing system fault is detected, door will stay in or return to the open position and revert to constant pressure close function for partial operability until fault is corrected Standard Operator Features • High efficiency UL Listed inline gear drive motor operator • 2 HP minimum continuous duty motor operates on 208230v-3ph or 460v-3ph power source • Auxiliary hoist for emergency hand chain operation in the event of a power failure • Integral speed governor to prevent curtain free-fall in the event of operator component failure • Variable speed controller with adjustable soft startstop feature • Average operating speed of approximately 24” per second to open, 12” per second to close – slowing substantially prior to full open and full close positions • Solenoid actuated brake, adjustable limit switches, non-resettable counter, adjustable reclose timer, delay on reverse • Auxiliary transformer is included to support secondary sensors and ancillary control devices • Wall mount control panel – connected to the motor operator via pre-assembled wiring harnesses

Ventilated Doors are Service Doors with curved or flat slats that are perforated with 18″ holes on 316″ staggered centers providing ventilation and visibility throughout the curtain.

Weather-Edge Doors are Service Doors that include a flat slat curtain and weather seals on the bottom bar, guides and hood for enhanced resistance to water, dust and air infiltration.

• Model No.AR-D2

Insulated Fire Doors utilize a double-slat curtain construction with a mineral wool core to combine the fire protection properties of HL fire doors with the benefits of thermal insulation and sound control for openings up to 44′ wide and 24′ high. Insulated Fire doors can be provided with an S-Label as air leakage rated “Smoke Door” assemblies. Fire Door Alarm Releases provide an interface between a fire door and an alarm systemsmoke detectors to allow automatic closing to be initiated by the alarmdetectors. They can be used on new or existing manual or motor operated fire doors (rolling or sliding). Model AR-D is a basic fail-safe time delayed release device.

The “low-profile” design of these compact but efficient Motor Operators and Fire Door Motor Operators means that no additional clearance above the top of the door coil is normally required. Lawrence motor operators are c-UL-us Listed and UL 325-2010 compliant. A large selection of Controls and Accessories are available for access control, obstruction sensing, egress functions, as well as wiring and environmental modifications.

• SeriesDC and LT

Folding Gates – also known as scissor, accordion, expanding, or collapsible gates – are available in the rugged double-channel construction of the DC Series, the performance-designed economy of the EG Series, and the commonly seen “lazy tong” design of the LT Series. Most gates can be either single sliding or bi-parting, and can roll on floor casters or in tracks.
