When exterior wind pressures or security issues arise and a floor closer is the best way to close a door but lighter opening forces are desired, the Rixson^® 2900 Automatic Opener is the perfect solution.

Low energy operators are not designed for high traffic or heavy doors because the mechanical closings inside are not strong enough to control the door.

By using a Rixson heavy-duty floor closer (existing or new installation) along with a Rixson 2900 door opener, there is no need for the extra expense of a high energy operator.

There is no special templating for either the floor closer or the operator.

2900 Low Energy Automatic Door Opener

Overview

The Rixson^® 2900 is a “low energy” power door operator designed to automatically open and close doors with a lower energy opening force.

The American with Disabilities Act (ADA) is a law administered by the U.S. Department of Justice. Its guidelines under ADA Regulation for Title III are detailed on the ADA website: www.ada.gov.

The Rixson 2900 aids in complying with ADA and ANSI A156.19 requirements. It functions using an A/C motor and hydraulic pump to activate a heavy-duty floor closer controlled by an Electronic Limit Switch (ELS) circuit board. The Rixson 2900 is your best choice in a low energy power door operator with its:

Architectural Specifications

Specifications

Heavyweight high-traffic doors that require automatic opening shall use the low energy operator in conjunction with a heavy-duty floor closer. Operator shall be for opening of door only.

Door shall be installed in the floor and shall have separate and independent closing speeds with back check turned to lightest setting.

Door controls (interior/exterior) for swinging doors shall be low energy operators. Door closing force shall be adjustable to ensure adequate closing control. Door operator shall have an adjustable backcheck feature to cushion the door opening speed if opened violently. Low energy operation to cycle the door open as controlled by the body/pump and motor assembly adjustments. Power operator unit shall provide conventional door closer opening and closing forces unless the power operator motor is activated by an initiating device. Motor assist shall be adjustable from 0 to 30 seconds in 5 second increments. Motor assist shall restart the time cycle with each activation of the initiating device. Unit shall have a three-position selector mode switch that shall permit unit to be switched “ON” to monitor for function activation, switched to “H/O” for indefinite hold open function or switched to “OFF,” which shall deactivate all control functions but will allow standard door operation by means of the internal mechanical closer. Door control shall be adjustable to provide compliance with the requirements of the Americans with Disabilities Act (ADA) and ANSI standards A117.1 and A156.19.

All operators shall meet UL, cUL, UL10c and UL10B standards. All operators are to be fire rated. All operators to have push and go function to activate power operator or power assist function. All operators to have push button controls for setting door close and door open positions. All operators to have open obstruction detection and close obstruction detection built into the unit. All operators to have door closer assembly with adjustable spring size, backcheck valve, sweep valve, latch valve, speed control valve and pressure adjustment valve to control door closing. All operators to have motor start-up delay, vestibule interface delay, electric lock delay and door hold open delay up to 30 seconds. All operators shall close door under full spring power when power is removed. All operators to have inputs for smoke ventilation doors, which allow doors to power open upon fire alarm activation and hold open indefinitely or until fire alarm is reset. All operators to have a presence detector input to prevent a closed door from opening or a door that is fully opened from closing. All operators to have a hold open toggle input to allow remote activation for indefinite hold open; door closes the second time the input is activated. All operators to have vestibule inputs to allow sequencing operation of two units. All operators to have a 24 VDC @ 500 mA output for controlling electric strikes, electromagnetic locks or radio frequency receivers. All operators to have an SPDT relay for interfacing with latch retraction exit devices, electric strikes, etc. All operators to be hard wired with power input of 120 VAC@60HZ
