Electric strikes
An electric strike is an electromechanical device installed on the door frame allowing an electrical
opening.
Installation modes
Flush mounted electric
Rim electric strike installation
A flush mounted electric strike is a mechanism body installed into the
door frame and it’s fixed on using a plate.
A rim electric strike installation is installed onto the door frame in case is
not allow a flush mounted installation. It consists of a mechanism body
and an electric strike cover.

Operating modes
Standard mode
Fail safe - (500)
An electric strike with a standard operating mode remains locked until it
recieves an electrical pulse, as long as it lasts the electric strike unlocks
the door allowing the door access.
Function 500 or “fail safe” works in a inverted way, that means that the
electric strike remains open until an electric pulse closes de door. In case
of power cut the doors stays open helping people to leave the building.
Reversible / Non reversible
No radial / Radial
Inside the full range of electric
strikes we can clasify between non
handed / handed and reversible /
non-reversible
Every symmetrical electric strike is
reversible so non handed, they can
be installed in both Din left and
Din right doors
NO RADIAL
RADIAL
Radial feature incorporates a latch that spins on a displaced axis
towards the bottom of the electric strike allowing to reduce its
movement area. The instalation is easier, more aestheic and allows a
smaller cutout in the frame of the door.
Non reversible

Timed delay action
Timed delay action allows the opening in a defined period of time. When electric strike is powered, the door is ready
for its opening during a period of time defined by the electric power impulse length (between 5 and 30 sec.) It locks
again by itself if the door is not open in that time.

Additional mechanical features
Delay action
Delay action contact function allows an access when electricity is applied to the electric strike. This access does not have to be inmediate. The door
remains open since electricity is applied until the door is open and closed again. Dorcas provides different delay action contact systems depending
on the built in construction of the electric strikes.
Delay action contact mechanism (A) allows
the door to remain open until an access
happens. This feature is possible thanks a
bolt on the front of the electric strike that is
activated when electric power is supplied.
Monitored - (305)
This version has a built in microswitch with
NO/NC contact informing if the door is
open or closed thanks to additional wire
output , then a security or access control
system can use this information providing
multiple applications. (alarms, access
controls, gates...)
Sliding delay action contact mechanism (Ab) is a new
feature built into some of the most innovative DORCAS
electric strikes. The delay action contact mechanism is
improved by a system that moves along with the
external latch allowing the delay action system to work
in any regulation of the mechanism.
Built in delay action provides the electric
strike the delay action contact function
without any external piece or mechanism
thanks to its internal construction. It is
recommended a short electric pulse for its
correct operation performance.
Unlatching mechanism
Flex
Unlatching mechanism lever allows to let the electric
strike open permanently. If you turn it again, it recovers
its normal functioning. This option is optimun for
neightbourhoods, constructions…
Adjustable external jaw consists in a latch
divided in two parts, the external part
allow to adjust the reception of the door
latch in a wider range making it easier its
installation.
TOP cover - Serie 99
99 model is a compact electric strike available to work in VAC/DC in a range from 10 V to 24 V. It is able to work in two operating conditions:
normally closed (NC) and normally open (NO). Last one is inverted system in DC current.
The main novelty is the TOP cover incorporation that guides the latch to slide easier, improving the working conditions.

If door includes joint, some low consumption models could not open the system
due to the generated pressure. Pressure can be regulated adjusting the flex latch.

VAC current
Function known as 400 or “fail secure”. It works like the standard
function (N) but you can keep more over the power supply
continuously, for instance with a switch. It is used as a low consumption standard mode.
Depending on the installation type, sometimes VAC working is more
indicated. That is why we offer our models with that option. VAC
electric strikes very short electric pulse in order to open the door.
Monitored Connections
Electric connections
Electric strikes work usually without polarity.
A diode can be installed to work with polarity.

Caution
1- Before starting connection, please check the electrical
features as well as the voltage and the current strenght of the
power supply.
2- Follow the manual and connect the cable as indicated on
the diagram.
3- Fit in the electric strike on the plate using screws.
Electric strike could be damaged in some wrong using
conditions:
-Voltage is higher than rated. Check voltage output before
installation.
-Do not oil or lubricate the electric strike, this could damage
internal parts.
-Paint, dirty or wet may affect to the electric strike functions.
4- Fit in the assembly electric strike and plate to the door
frame using screws.
5- Adjust if it is necessary flex system.
6 - Use the electric strike.
