Lawrence Doors

United States

The Lawrence Model PD is a truly high performance rolling door designed for 500, 000 cycles usage and with an averageoperating speed of approximately 24 inches per second to open, 12 inches per second to close. PD High Performance Doorsare 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 FeaturesType 3 standard flat slats or Type 33 insulated slats* (R5) available in galvanized steel, stainless steel, or aluminumDelrin endblocks attached to slats to reduce frictionScratch-Guards protection system to reduce finish wear andoperating noiseTubular bottom bar fabricated from aluminum extrusionsGuides fabricated from 14" steel shapes with replaceableUHMW wearstripsOuter and inner guide are separately removable to provide easyaccess to curtain for inspection and serviceSpringless barrel design minimum 8 58 diameter pipe and1 12" shafts*Doors with insulated slats are limited to 14 ft. highStandard Safety FeaturesMonitored sensing edge to stop and reverse a closing doorupon contact with an obstruction rubber dual-chamber profiledesign with integral isolated conductive elastomer switchesSecondary monitored light curtain to stop and reverse a closingdoor upon sensing an obstruction in the opening.If a sensing system fault is detected, door will stay in or returnto the open position and revert to constant pressure closefunction for partial operability until fault is correctedStandard Operator FeaturesHigh efficiency UL Listed inline gear drive motor operator2 HP minimum continuous duty motor operates on 208230v-3ph or 460v-3ph power sourceAuxiliary hoist for emergency hand chain operation in the event of a power failureIntegral speed governor to prevent curtain free-fall in the event of operator component failureVariable speed controller with adjustable soft startstop featureAverage operating speed of approximately 24 per second to open, 12 per second to close slowing substantially prior to full open andfull close positionsSolenoid actuated brake, adjustable limit switches, non-resettable counter, adjustable reclose timer, delay on reverseAuxiliary transformer is included to support secondary sensors and ancillary control devicesWall mount control panel connected to the motor operator via pre-assembled wiring harnesses

High Performance Grilles are designed for 300, 000 cycles usage with an approximate average operating speed of 24 inches per second to open and 12 inches per second to close. They are well suited for parking garages and other applications where traditional roll-up grilles do not adequately meet the demands for very high frequency usage or the desire for higher speed operation.Model PG features a springless barrel design, enhanced heavy-link aluminum grille curtain, innovative hinged steel guide system with replaceable UHMW wear strips, 2 HP motor operator with variable speed controller and soft startstop, dual monitored sensing systems, and more.

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.

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.

Insulated Doors combine flat front and back slats with foam insulation and weather seals on the bottom bar, guides and hood, resulting in a Service Door that also provides maximum climate and temperature control.

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.

Fire Doors combine many design features of a Service Door with specialized construction, automatic closing and Easy-Reset or Auto-Reset functions to provide state-of-the-art fire protection for openings up to 60 wide, 50 high, 1320 square feet.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.

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.

Counter Fire Doors provide the same high levels of fire protection, and many of the same features of Fire Doors including Easy-Reset and Auto-Reset functions but in a more compact door design.Counter 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.

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.
