C4 Security Portal


If you need 2 security portals for high throughput rates and easy bidirectional traffic but think 
you did have the space the C4  could be the answer. The C4 allows you to install 2 portals in a 
space of 1750x995mm a saving of  240mm over the next  narrowest solution. The C4 is a perfect 
‘interblocked’ 2 door system—when one door is open it blocks the other door in that lane so it can 
not open creating higher security. Note that this feature stops both doors in
1 lane being open simultaneously for emergency egress.

Reversible motors with permanent magnet, working power 24VDC. Provided with an encoder for 
continuous control of the door position. Door are provided with electronics control of motor torque 
for door safety stop in the presence of an obstacle.
In the event of a power failure (and a fully discharged emergency battery backup) the non-secure 
door will be closed and locked to prevent intrusion.


Each Portal is provided with a lever, handle or crank for unlocking the portal in an emergency. One 
is located inside the portal and will only open the door on the non-secure side ensuring security 
is not compromised.
The portals have a special mechanical mechanism which allows the opening of the secure door (only) 
in cases when a forced opening is required. Since the mechanism is situated on the secure side and 
it opens only the secure door, security is not compromised.
IR safety sensors to detect the presence of an obstacle in the doors and prevent them from closing 
to avoid injury. Additional optional IR safety sensors are available.
The control electronics monitor the torque required to close the door to detect for obstructions
The portal can be connected to the building fire alarm/ emergency. In the event of a fire a door 
can be set to open so no one is trapped in side the portal
All portals are provided with an Emergency Battery backup in the event of a power failure. The 
Portal can work on the Emergency Battery for up to 6-8 hours of continuous operation. An indicator 
light and message on the control panel inform the user the Emergency battery is in use.

Control Panel and Intercom

A multifunction touch sensitive Control Panel has a clear display to allow for simple understanding 
of the portals operation. The panel also allows easy changes to portal settings and operation.
One push to talk service intercom is integrated on the control panel and another one on the 
security  portal non secure  side Traffic  Light.
