Dortronics 4700 Series PLC Man Trap Interlock (Door Interlock) 2 Door SystemPlease note that magnetic locks and electric strikes and doors and door closers are not included. Please call or email if you need help choosing which will work best for your installation.
Secure 2, 3 or 4 Door For 5 and 6 door systems see below. Commonly know as bank or airport interlocks or interlocking systems, interlocking Mantrap or door interlock or air lock. This product is very customizable and can be configurd to do just about anything you need so call us to discuss your system.
The Interlocking 4700 series 2-Door Controller provides
power and control for two doors with
electric locks. Up to four (4) doors may be
interlocked with the Door Controller.
Air-Locks or Security Portals
Suitable for environmental or security control,
the door interlock logic allows only one door
to be unsecured at a time. The controller may
be configured to have both doors locked or
only one door normally unlocked to allow
faster egress.
Universal R-E-X Inputs
Request-for-Access devices may be normally
open or normally closed dry contact devices.
Both types may also be used simultaneously.
Traffic Indicator Lights
Relay outputs are provided to control traffic
lights. For user convenience, a green light is
typically used to signify a door is ready for
access. A red light is usually lit to indicate that
a door is un-accessible. Alarm relay outputs
are also available for special requirements. Integral 12/24 VDC Power Supply is included.
The built-in low voltage power supply provides
sufficient current to operate 12 or 24 VDC
electromagnetic locks or strikes, including
redundant maglocks and strikes on each door
for high security projects. The heavy-duty
power supply assures reliability for extended
usage in the most strenuous environments.
Fire Alarm Input/Output
Ready for hook-up to the fire system, no additional
relay interface devices are required. An
alarm output is also provided for monitoring
the control system.
Total Protection & Back-up Power
The 110 VAC input and DC output are fused to
protect the system against overloads and shorts.
The switching regulator prevents excessive
current draw. The optional back-up batteries
are automatically charged to provide immediate
12 or 24 VDC output upon loss of AC power.
Remote Control & Monitoring
The #7600 Annunciator/Controller is also
available for integration with this system. 2, 3 or 4 Door Security

Secure Door Interlocking
Only one door may be unlocked at a time.
Unlocking one door automatically secures
all other doors. A request for access will
inhibit the REX inputs for all other doors
unless another door is already unsecured.
For faster traffic flow, a single door of a
2-door mantrap may be left unlocked. A
request for access at the secured door will
cause the unlocked door to be secured.
Once both doors are secured, the request
for access will be granted.
Traffic Indicator Lights
Outputs (from lock power) allow red and
green lights to be utilized for user feedback.
A green light indicates that access
is permitted, while a red light signals that
the other door is open and access is
denied at this door.
Multi-Door Interlocks
See the Dortronics programmable door
controller for mantraps requiring more
than two, three or four interlocked doors.
Quick Easy Installation
Installation is fast, from mounting the
enclosure to the connection of wiring. No
need to add additional relays for alarm
monitoring or the fire alarm interface.
Large barrier terminal blocks are provided
for all field device connections.
Reliable Operation
The unique design of the power supplies
insures a reliable source of lock power in
all situations. Components that exceed
normal specifications are used to extend
the operating lifetime.
Optional Features:
xBAT - Dual 7-AH rechargeable batteries
for 12 or 24 volt back-up power
xCAM - Hinged cover cam lock with key

Secure Interlock Door Control
The 4700 series Programmable Logic Controller is an
economic way to control up to 4 interlocked doors. The
controller logic sequences simultaneous requests for
access and monitors unsecured doors to maintain the
highest level of security at all times.
Environmental or Security Control
Suitable for air locks or security mantraps, with up to four
normally unlocked doors or three normally locked doors.
The controller may also be customized to control
automatic door openers and provide timing and logic
sequences for biological wash-down controls.
Typical configurations also provide outputs for traffic lights,
forced doors and an emergency panic release input.
Access Control Compatible
Any access control system can be used with the 4700
series controllers. The request for access input
recognizes any normally open dry contact.
12/24 VDC Power Supply
The 4700 series PLC controller is paired with a heavy duty
4-amp power supply that includes a Fire Alarm connection
for emergency egress and provides power to operate the
maglocks and electric strikes and traffic lights.
An alarm output is also provided.
Typical Configurations:
#47211-U Standard 2-Door / 1-Room
Normally Unlocked
#47211-L 2-Door / 1-Room
Normally Locked
#47321-LU/S 3-Door / 2-Room

2-Shared Doors
Operation :
Only one door may be unlocked or open at any time.
Unlocking or opening one door automatically
secures all other doors within the designated area.
A request for access at any normally locked door will
inhibit the REX inputs for all other locked doors and
secure all unlocked doors in the area.
Lock relay contacts will switch low voltage power to
maglocks and/or strikes. The lock relay contacts
also allow low voltage red and green LEDs to be
utilized for indication of lock status. For user
feedback, typically a green light indicates that
access is permitted, while a red light signals that
another door is open and access is denied at this
door.
Some outputs may also be programmed to indicate
alarm conditions. Other customized operations may
be factory programmed to allow timed sequences,
etc.
