LB - 211 AUTOMATIC FLAP BARRIER

LB-211 Automatic flap barrier is designed for controlling access of people (also people in wheelchairs) and transport of goods outside the main system of customer service. In large factories it can be used for the control of passage of people outside the system of work time registration, while in public and business space it can be used to order and direct the passage of people. The gate`s entrance is wide enough to be utilized as one of the ways of evacuation. It can be bi-directional or mono-directional. The coefficient MTBF equals 4 million cycles. Thus it can be used in high traffic / volume environments. The impulse which releases the blocking arm may be given by the short circuiting switch, outside access control reader or photo-barrier.

1. Product features:

• all inner steel elements are galvanized, and cabinet outer shells and cover made of acid-resistant stainless steel, all supports and arms are made of stainless steel in a polished finish,
• two-way mechanism enables to use one turnstile both for entering and leaving with a possibility to block backward movement (in prohibited direction), turnstiles can thus be available in clockwise, counter-clockwise or bi-directional passage,
• in case of power failure or fire alarm arms may be turned freely in both directions without a necessity of additional declutching,
• special muffling elements increase the mechanism`s durability and guarantee silent operation
• in-built clutches regulate the support power of arms, protect the device from defects and the pedestrians from possible injuries,
• microprocessing driver which can be easily configured facilitates cooperation with various systems of access control, photo-barriers. It can be also steered manually.
• interfacing to computer attendance systems
• interior and exterior application, also in areas with frequent heavy snowfall and rainfall,
• no outside flange, and foundation bolts hidden inside the cabinet make it possible to use the whole space between the bars and protect the passers from tripping
• access to the inside of the cabinet is secured with locks to prevent unauthorized interference or theft

2. Steering:

The blocking system is released by the opening impulse and the wing is opened by 90^o angle in the direction set by the steering mechanism. After a set period of time the wing returns to its prior blocking position. If the next impulse is given while the gate closes, the wing will change its direction and will open again. In the final phase of opening, the programmer signals a completed passage.

4. Additional equipment:

• diode pictogram built in the cover shows information on the direction of passage, stand-by status or blocking,
• outside acoustic device 12VDC signalling any unauthorized entrance

5. Maintenance:

• a device does not require conservation
• general control of the inside: once a year every 500 thousand passages
