Rotation - A left-hand rotation allows a person to pass through a turnstile or highgate with the rotating mechanism on their left. With a right-hand rotation, the mechanism is on their right as per the following illustrations:
Cabinet
Highgate
Direction Control Functions
One-Way Operation - Permits traffic to pass through
a turnstile one way, only (left or right rotation). The opposite way is
barred.
On models MTL-2,
MTL-3,
and MHG-1,
a cam action is designed to lock the arms in the 120° position. The
basic 3-arm cabinet models MTL-3
can be provided with free access or controlled access as described under
"Access Controls". The MTL-2
and highgate MHG-1
are always a controlled access.
Two-Way Operation - Permits access through the turnstile either
way, with the opposite way barred. This is always a controlled access.
Available as standard on highgate model MHG-2
and as an option on the 3-arm cabinet models MTL2 and
MTL-3.
Access Controls
Full Stride Access
- On models MTL-1
and MHG-1
- one way operation is a free rotational movement with a mechanical clutch
to prevent counter rotation.
Controlled Access - The access through a turnstile whether for
one-way or two-way operation can be controlled by any of the following
functions:
- Mechanical Unlock - model MTL-3 - This provides a mechanical linkage which is activated by the control operator to permit access. The arms will automatically lock at the 120° position until re-activated.
- Coin or Token Operation - On models MTL-3, MHG-1 & MHG-2. Access is provided automatically after depositing the correct coin or token. A lockable compartment is provided as a receptacle for coins or tokens. Arms will automatically lock in the 120° position until re-activated.
- Electrical Control - On models MTL-3, MHG-1 & MHG-2. This can be installed either on the unit or in a remote location and is activated by the control operator once identification is made.
- Security Card - On models MTL-2 & MHG-1. Operates identically as a coin or token, but with a plastic access card issued to authorized personnel.
- Electronic Control - With the sophistication of the electronics industry, various means of access control functions are available, including handprint access sensors, verification of personnel entrance sensors, etc., to provide a high degree of security where required. Please contact us to discuss your individual requirements.
- Timed Relay - On models MHG-1 and MHG-2. After activating unlock mechanism by token, card, etc., the mechanism is locked automatically after access. If no one passes through, the timed relay with adjustable time delay will re-lock to prevent passage.
- Fail Safe - On models MHG-1 and MHG-2. In the event of a power failure, the mechanism will allow free access (fail safe)
Additional Options
Counters
- To provide an accurate read-out of the number of people passing through
a turnstile or highgate. Preferred with our equipment is an electrical
counter with digital read-out. When electrics are used for controlled
access, the counter is connected to the 24 V-DC supply. When no electrical
control is present, a battery-operated counter with a ten year life is
fitted.
Mechanical counters are available as an option and are activated by a
mechanical linkage.
- ALL counters supplied have reset capabilities.
- ALL counters supplied have a lockable cover permitting only the keyholder access to the readings.
- Additional counters for remote installation are available.
Out-Of-Service Lock - This is a keyed function which locks the
complete mechanism allowing no access either way.
Finishes:
- Stainless Steel - Type 304 - #4 Finish.
- Galvanized - Hot-dip applied.
- Epoxy - Electrostatically applied powder, oven cured at 400° F.
