Overview |
 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.
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.
This is caused by release of the electromagnetic
solenoid, thus allowing the door closer to perform its function.
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.
These units will operate as a standard door
control, whether or not power is applied.
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. |

| Features Include: |
 Door closing control by the proven DORMA 1800 Series door closer with spring power
adjustment and adjustable hydraulic backcheck. |
| Two noncritical adjusting valves (sweep and latch) work to provide consistent closing
speeds under a wide variety of temperature changes. |
| Interfaces with new or existing smoke/fire control systems. |
| Handed with full cover. |
| Can be connected to main electrical current 24 VDC, 24 VAC, or 120 VAC. Specify only
on units without detector. |
| Unit can stand alone, independent of other systems. |
LED blinks red every 15 seconds showing that the unit is on guard. When in alarm, the
LED glows red constantly. |
| Test feature and alarm reset built into LED indicator light pipe. |
| Detector LED and hold solenoid latch in alarm mode and require manual reset. |
| Certification |
The DORMA 1800 Series is listed by U.L. and C.U.L under
their continuing reinspection programs.
The DORMA 1800
Series is BHMA certified to conform to the requirements of
ANSI A156.15. California State Fire Marshall (CSFM)
approved.
MEA certification pending.

| Specification |
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.
The H model to have positive single-point hold
open at any angle between 20° and 180° when current is
applied.
The FS model to operate without any closing force
between 0° and 180° when current is applied. (4°–6° fall away
may occur.)
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.
| Optional Specifications: |
The 1800 Series will have manual on/off switch to bypass hold
open function.
All 1800 devices will have exposed wiring
bracket for surface wiring. |
| Installation: |
| Top Jamb or Track. |
| Finishes: |
Standard Sprayed Finishes:
 Primed for Painting: 600.
Aluminum: 689.
Bronze: 691 (Dull), 690 (Statuary),
695 (Dark Duranodic).
Gold: 696.
Black: 693.
|
Warranty:
Closer: 25 Years.
Electrical Component: 2 Years.

Options:
(BYP) - Concealed manual on/off switch to bypass hold open
function. Access hole is drilled in the cover.
(EXP) - Exposed wiring bracket |
| Electrical Specifications: |

and N.C. (under power) trouble contacts. Five detectors may
be interconnected for zone control of doors or pairs of doors. |
| Transient Protection: |
| To meet U.L. 268 Standard. |
| Replaceability: |
| Field-removable from door closer housing. Return to factory

1856 Track Installation |
 Door closing control by the proven DORMA 8600 Series door
closer with spring power adjustment and adjustable hydraulic
backcheck.
Two noncritical adjusting valves (sweep and latch) work to
provide consistent closing speeds under a wide variety of
temperature changes.
Interfaces with new or existing smoke/fire control systems.
Handed with full cover.
Can be connected to main electrical current 24 VDC, 24 VAC,
or 120 VAC. Specify only on units without detector.
H – Single point 20° to 180°.
H can be manually released.
FS – 0° to 180°
Optional concealed on/off push switch to bypass hold open
feature. Specify BYP.
Concealed wiring application standard. Surface wiring option
available if specified. Specify EXP.
Fail-safe type design releases hold open/free swing and closes
door when input current is interrupted or alarm state is signaled.
Both H and FS units function as standard door closers when
there is no current applied.
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. |
