Norton 7223MPSO-LH-24VDC-689 7200 Series Electromechanical Closers Aluminum Painted

7200 SeriesElectromechanical Closer/Holder

The 7200 Series Electromechanical Closer/Holders combine the functions of an electromechanical door holder with the 7700 series door closer.

Features

Master Unit: 7200MPDO
Consists of an on-board power supply (for 120VAC input option) or a terminal strip (for 24VDC input option), an integral smoke detector module and a door closer assembly with internal electro-hydraulic holder capability. A Master Unit can control a single door or one leaf of a pair of doors. A 24VDC Slave/Support Unit is required on the opposite door leaf.

Certifications:

• ANSI/BHMA A156.15 certified

• UL / cUL listed for use on fire rated doors

• UL10C listed for positive pressure fire test

• This product is manufactured in an ISO 9001 facility

Explanation of Features: Aluminum Alloy Housing:

• Closer bodies are constructed of a special aluminum alloy, carefully selected to accommodate interactive steel components and operating conditions.

Rack & Pinion Operation:

• Provides a smooth constant control of the door through its full opening and closing cycle.

Spring Sizes:

• Specify closer size 3, 4 or 5. Size 6 available with 7290 overhead concealed units.

Sweep Speed Control Valve:

• Allows adjustment of door speed from the door’s full open position down to approximately 10° from the closed position.

Latch Speed Control Valve:

• Allows adjustment of door speed from approximately 10° down to the door’s fully closed position.

Adjustable Backcheck Cushioning:

• Provides control of the door in the opening cycle, beginning at approximately 75° of door opening. It slows/cushions the door opening, when the door is forcibly opened beyond its pre-adjusted limits.

Adjustable Backcheck Position Valve:

• Allows the door opening position, where backcheck cushioning begins, to be adjusted to a greater door angle, up to a maximum of 20° farther (approximately 95°).

Handed:

• Specify right or left hand when ordering.

Selective Hold Open (Standard):

• The door will hold open at any degree of opening beyond a pre-set hold open point, up to 175°, with a maximum allowable door opening of 180° (exception series 7250 at 110°).

Infinite Hold Open:

• The door will hold open at any degree of opening up to 175°, with a maximum allowable door opening of 180° (exception series 7250 at 110°). Can be set in the field by turning cam.

Fail Safe:

• In the event of a power failure, the solenoid will de-energize and the closer/holder will then operate as a normal door closer.

Wiring Option:

• All 7200 Series Electromechanical Closer/Holders will accommodate either concealed or surface wiring.

Selective Hold Open Switch and Cam:

• The Selective Hold Open starting point is determined by a switch and adjustment cam assembly. The cam is attached to the upper pinion shaft by means of a machine screw. As the door is opened, the pinion shaft will rotate the cam and operate the switch to the "on" position to initiate hold open. When the door is closed, the pinion cam will operate the switch to the "off" position. The cam is factory set to operate at 80° of door opening. The cam can be easily field adjusted to operate at virtually any degree of door opening.

Explanation of Features - Smoke Detector: Fire/Smoke Control Circuit:

• Interprets the signal from the detector and provides switching contacts to interrupt hold open solenoid, to sound alarms, etc.

Trouble (Relay) Contacts:

• Normally closed in standby condition, these supervisory contacts monitor the continuity of power within the detector circuit. Any power interruption within the detector circuit will open these contacts. They can then be used to simultaneously indicate a Trouble Condition to the Alarm Panel on a separate trouble circuit.

Alarm (Relay) Contacts:

• Normally open in standby condition (operating and sensing for smoke condition). These contacts close during an alarm condition (smoke detected) and may be used to switch power from the solenoid to an optional local alarm.

Locked-In Alarm:

• The unit which alarms must be manually reset. This can be accomplished by remote control from the alarm system panel or by the reset switch in the smoke detector module. Reset switch is accessible through the center louver in the cover. Reset by rotating LED chambers using small flat blade screwdriver.

Indicator Lights:

• Normal Mode: A red LED flashes once every eight (8) seconds.
• Clean Mode: A red LED flashes once every second.
• Alarm Mode: A red LED illuminates continuously.

Test Switch:

• Permits door to be released from hold open without causing a "trouble condition" at the alarm panel. Allows for periodic testing of the automatic door release function.

Master Units: 7210/7250
