DORMA 1856 Series

Holder/Release Device with Integral Door Closer, with or without Smoke Detector

The 1800 Series is an electromagnetically controlled door closer, available with or without integral smoke detector-power supply for use on fire and/or smoke barrier doors.

Holder/release devices ANSI/BHMA certified.

  • Available with or without integral smoke detector
  • Hold open function
  • Swing free function
  • Reliable door closing control

Product details

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.

Swing free function

The DORMA 1800 Series Swing Free (SF) 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.

Smoke and fire control

The 1800 Series door closer will allow unimpeded, easy access throughout a building while not affecting its integrity to control the spread of smoke and/or fire.

Door closing control

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.

Dormakaba 1856-HT-RH-SD-689 – Frequently Asked Questions

1) What is the DORMA 1856 Fire Life Safety Series used for?
The DORMA 1856 is a surface-mounted electromagnetic holder with release track closer and integrated smoke detector. It holds fire doors open during normal operation and automatically closes them when smoke is detected or power fails. Used on corridors, stairwells, and egress paths requiring fire/smoke compartmentalization.
2) What door types and weights are compatible with this closer?
Compatible with metal fire doors up to 250 lbs. Suitable for single-acting doors in commercial and institutional applications. Verify door weight, width, and construction with manufacturer specifications. Not recommended for wood doors or high-frequency traffic areas.
3) How do you determine proper door handing for installation?
This model is designed for pull side mounting. Stand on the side you pull the door toward you to open. The closer mounts on the frame header above the door. Verify handing matches your door swing before ordering. Template shows exact mounting positions.
4) What finishes are available for the DORMA 1856?
Standard finish is aluminum. Custom finishes may be available through special order. Check with manufacturer for powder coat options if project requires specific color matching. Standard finish provides corrosion resistance for most interior applications.
5) What are the power requirements and electrical specifications?
Requires 24V DC power supply for electromagnetic holder operation. Power consumption varies by model size. Must connect to fire alarm system for smoke detection integration. Backup power recommended to maintain hold-open function during power outages. Consult electrical specifications sheet for exact requirements.
6) Does this closer meet fire door code requirements?
Designed to comply with NFPA 80 fire door assembly standards when properly installed. UL listed for fire door applications. Must be installed according to manufacturer instructions and local fire codes. AHJ approval required for specific applications. Verify code compliance for your jurisdiction.
7) What parts and accessories are included with the closer?
Includes electromagnetic holder, track closer mechanism, integrated smoke detector, mounting hardware, and installation template. Electrical connections and conduit sold separately. Replacement parts available through door closer parts inventory.
8) What are the basic installation requirements?
Requires solid mounting surface on door frame header. Use provided template for hole locations. Frame must support closer weight and door closing forces. Electrical connections to fire alarm panel required. Professional installation recommended due to fire safety integration requirements.
9) How do you maintain and adjust the DORMA 1856?
Monthly testing of smoke detector and release function required. Adjust closing speed with valve screws on closer body. Clean magnetic holder surfaces regularly. Check mounting screws for tightness quarterly. Replace smoke detector according to manufacturer schedule. Keep adjustment records for code compliance.
10) Are there similar models or substitutes available?
Other DORMA 1800 series models offer different mounting configurations and hold-open forces. LCN and Norton also manufacture electromagnetic door holders with track closers. Compare specifications carefully as mounting patterns and electrical requirements vary between manufacturers and models.
11) What field conditions affect closer performance?
High humidity can affect electrical components. Temperature extremes impact hydraulic fluid viscosity and closing speed. Air pressure differentials across door affect closing force requirements. Dust and debris interfere with magnetic holder operation. Indoor use only unless specifically rated for exterior conditions.
12) What measurements are needed before ordering?
Measure door width, height, weight, and thickness. Check frame depth and header space for closer mounting. Verify electrical rough-in locations for power and fire alarm connections. Note any architectural constraints or finish requirements. Review installation template against actual field conditions before ordering.
