FER-SRI-OTS 73x BG hold-open system set
with slide rail, with door-leaf coordinator, with electromechanical hold-open device, with smoke switch module RSM
Solution for 2-leaf doors with total door leaf widths up to 2800 mm
Tested and certified in accordance with EN 1155 and EN 1158
Tested and approved by DIBt according to the guidelines for hold-open systems
SRI door-leaf coordinator
Mechanical door-leaf coordinator (SRI) integrated into the slide rail to ensure doors are closed safely and in the correct sequence at all times
Microswitch in the active leaf supplied as standard: guarantees that the passive leaf closes if the active leaf is manually unlatched from the hold-open position.
Electromechanical hold-open device FE
Device that is integrated and pre-mounted In the slide rail and allows a door to be held open at a chosen angle until it is closed electrically
Set contains: 2 hold-open devices, electromechanical (FE); one for active and passive leaf respectively
The active leaf can be held open independently of the passive leaf at any time
Door leaf coordinator and electromechanical hold-open device integrated under continuous cover
Smoke switch module (RSM)
For supplying electricity to all components of a hold-open system (hold-open device, electromechanical hold-open magnet, fire detector, smoke release push-button and other elements).
OTS 73x series of door closers
Door closers in the OTS 73x series are not included in the scope of delivery of the hold-open device set and must be ordered separately.
When used in combination with the hold-open system set, two OTS 73x door closers must always be ordered.

2-leaf fire and smoke protection doors
Min. total door leaf widths:
Display 1: 1770 mm
Display 2: 1475 mm
Max. total door leaf widths:
2500 mm (OTS 735 BG)
2800 mm (OTS 736 BG)
Min. single-leaf width of passive leaf: 600 mm
Hold-open angle 85° – 140° steplessly adjustable
Standard installation opposite to hinge-side
Max. door opening and closing angle: 120°
Greater range of application with side opposite to hinges (BG) due to separate BG variant
e.g. opening angle of approx. 113° with an X-dimension of 100 mm
Depending on installation situation. Position door stop for max. door opening angle.
SRI-OTS 73x door-leaf coordinator for use on 2-leaf full-panic doors in escape and rescue routes
A suitable carrier bar must always be used with double-leaf full-panic doors installed in escape and rescue routes. This ensures that when the door is opened via the passive leaf (in emergency situations), the active leaf is carried at least as far as the beginning of the action range of the (SRI-OTS 73x) door leaf coordinator.
