DELTA SCIENTIFIC CORPORATION 

MODEL AG812 ACCESS GATE 

 
 

General 

 
The  Delta  Scientific  Corporation  Model  AG812  Access  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 AG812 Access 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 AG812 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.
