Overview

dorma The 1800 Series has been developed to inexpensively guard a single door opening from smoke and fire, in place of an array of expensive products. In addition, it will allow unimpeded, easy access throughout a building while not affecting its integrity to control the spread of smoke and/or fire.

dorma Upon interruption or loss of current in either the H or FS specification, the unit will automatically close the door from any angle of opening.

dorma This is caused by release of the electromagnetic solenoid, thus allowing the door closer to perform its function.

Dorma The DORMA 1800 Series Hold Open (H) function is designed for buildings where it is desirable to have smoke/fire doors in the open position under normal circumstances, but which must close upon loss of current.

Dorma These units will operate as a standard door control, whether or not power is applied.

Dorma The DORMA 1800 Series Free Swing (FS) function is designed for buildings where it is desirable to have fire/smoke doors operating as if there were no closing device fitted under normal circumstances, but must be self-closing under alarm or loss of current.

Specification

Dorma DORMA 1800 Series electromagnetic surface applied, fire/life safety, hydraulic door closer with or without integral smoke detector – power supply to suit hold open (H) or free swing (FS) specification.

Dorma The H model to have positive single-point hold open at any angle between 20° and 180° when current is applied.

Dorma The FS model to operate without any closing force between 0° and 180° when current is applied. (4°–6° fall away may occur.)

Dorma When the smoke density in the chamber of the 1800 detector exceeds the fixed threshold value, the alarm is given, the LED turns red, the circuit for the hold open device is cut off and the door closer immediately shuts the door.

Technical Details

1856 Track Installation

Door closing control by the proven DORMA 8600 Series door closer with spring power adjustment and adjustable hydraulic backcheck.

Dorma Two noncritical adjusting valves (sweep and latch) work to provide consistent closing speeds under a wide variety of temperature changes.

Dorma Interfaces with new or existing smoke/fire control systems.

Dorma Handed with full cover.

Dorma Can be connected to main electrical current 24 VDC, 24 VAC, or 120 VAC. Specify only on units without detector.

Dorma H – Single point 20° to 180°.

Dorma H can be manually released.

Dorma FS – 0° to 180°

Dorma Optional concealed on/off push switch to bypass hold open feature. Specify BYP.

Dorma Concealed wiring application standard. Surface wiring option available if specified. Specify EXP.

Dorma Fail-safe type design releases hold open/free swing and closes door when input current is interrupted or alarm state is signaled.

Dorma Both H and FS units function as standard door closers when there is no current applied.

Dorma Models without detectors can be powered directly by models with detectors, in which case solenoids from both modelsdeenergize under loss of power or an alarm condition.
