This turnstile offers the benefit of being more affordable that the prestigious Premier model due to its simpler lines and construction yet still projects the image of an elegant, robust and uncompromising unit. This turnstile can also be fitted with a stylish drop arm as it offers completely free and unhindered exit in an emergency situation. The battery power pack (which can be built into the turnstile unit or situated remotely) unlocks the arm from the horizontal position and drops the arm down to a vertical position. The added benefit of this option is the automatic reset once the arm has been dropped; the mechanism rotates on itself and then drops the arm back into posistion. Operation: Manually operated arms or drop arm functionality. Can be controlled via any access control unit which gives out a volt free contact (supplied separately). Free rotation on power failure or activation of fire alarm. Can be alarmed with under or over sensors. Unlocking mechanism adjustable from 2- 32 seconds. Optional Drop-Arm mechanism is available.
