General
The Delta Scientific Corporation Model SG1420 Security Gate is a heavy-duty unit designed to
meet the many needs of restricted traffic control. A large array of control modes are permitted,
including auto/manual operation in conjunction with local or remote pushbutton stations, timers,
radio controls, vehicle loop detectors, infra red detectors, ticket spitters, card readers, coin or
token devices, and computerized electronic tag systems. These devices may be used
independently or in combination. In short, any device which can provide a contact closure may
be used to vend or reset the Gate.
Safety
The Model SG1420Security Gate is equipped with an electric motor driving the gate arm
through a vee-belt/gear box system. Keep hands and fingers away from the unit interior when
power is on. Shut power off before adjusting limit switches or belt tension. Wiring to the terminal
strip should be made by a competent electrician according to the NEC (NFPA 70) and
applicable local codes.
Installation
The Model SG1420 is packed in a reinforced cardboard carton with an inner poly bog to guard
against moisture. Do not stack cartons or leave out in the elements until ready to set. Gate
model number and accessories are marked on carton top.
The SG1420 is to be located on a solid, non-combustible surface, such as concrete. Mark the
Gate location from the architect's drawings. Conduit for the Gate motor and controls must be
brought to the stub-up area within the Gate'' bottom opening (shown above). Foundation bolt
location can be marked from the Gate itself or from a template (Delta P/N D03180)
