effeff electric strikes in Vienna
effeff is the ASSA ABLOY brand for electric strikes and electromechanical locking. RIVA selects the correct model in Vienna according to the lock, profile, voltage, operating principle and door requirements, then integrates it with the intercom or access system.
effeff is a natural choice for electrical release and locking. Selection is technical: fail-secure or fail-safe behaviour, voltage, latch and door rules must all match.
- An intercom or access system should release the door.
- A compact electric strike must match an existing lock.
- Automatic locking and safe exit must work together.
- The issue is a stiff mechanical lock with no electrical function.
- You need a full access-control platform, not one door component.
- Photos of the latch, strike plate and frame cut-out
- Available voltage and connection type
- Any fire, smoke or escape-door requirement
Manufacturer overview
The electric strike is one part of the complete door
An electric strike does not replace the mechanical lock; it releases the latch electrically. Reliable operation depends on the latch, strike plate, installation space, door pressure, power supply and operating logic working together. Fire, smoke and escape doors have additional requirements and cannot use an arbitrary standard model.
Real product examples
effeff products worth comparing
These are orientation examples, not a promise of stock or a one-size-fits-all recommendation. Each card explains the useful fit and the first compatibility check.
effeff 118
Best fit
Standard doors released by an electrical pulse
Its compact, symmetrical shape fits many mortise locks and mounting positions.
effeff 138
Best fit
Special uses that must release when power is lost
The fail-safe principle locks while powered and releases without voltage.
MEDIATOR
Best fit
Apartment and commercial entrances with intercom release and panic exit
The door stays locked from outside but can always open from inside through the panic function.

effeff solution areas
Standard electric strikes
Compact releases for residential, office and everyday doors with varied optional functions.
Special and high-security strikes
Models for greater holding force, external use, monitoring and specific door profiles.
Electromechanical locking
Locks and components for access control, emergency exits and defined safety logic.
Applications
Typical applications
- Entrance doors released from an intercom or push button
- Office and retail doors operated by card reader, PIN or central release
- External doors where weather resistance, holding force and monitoring matter
- Existing systems with a defective strike, incorrect voltage or mechanical misalignment
Specification
Identify voltage and operating principle correctly
Visually similar effeff strikes can behave differently electrically. The label, supply, fail-secure or fail-safe principle and required monitoring contacts are confirmed before replacement.
Electrical data
Voltage, current type, duty cycle and protection circuitry must match the control equipment.
Mechanical installation
Latch position, strike plate, profile cut-out and door pressure determine reliable release.
Safety function
Fire, escape, monitoring and outdoor use require variants approved for those conditions.
Choose by situation
Which effeff direction fits your case?
Start with the problem you need to solve. The product is the result of the check, not the starting assumption.
The entrance must stay locked during a power cut.
A fail-secure model such as the 118 family is the usual starting point.
Compare
effeff 118
Confirm the complete door function and local rules.
The door must release without power.
Fail-safe operation may fit, but it is not automatically an escape-door solution.
Compare
effeff 138
Check the standard, use and security concept.
The main door should always lock and still open by intercom.
MEDIATOR is an important comparison candidate for this exact conflict.
