momentarily the light will switch on for the light timer period and automatically switch
off. By pressing and holding the pushbutton down for 3 seconds the lights will switch
on and remain on. The status LED (if fitted) will flash once every 2 seconds to
confirm this. To switch off the lights press the pushbutton momentarily. If courtesy
lights are fitted to the controller, and the pedestrian keyswitch is operated, the
courtesy lights will flash for 5 seconds before the gate opens. This warns the
pedestrian that the gate will open within 5 seconds allowing time to remove the key
and stand back from the gate.
PRE-FLASHING
The courtesy light can be programmed to flash for 5 seconds before the gate starts
to open or close. The courtesy light timer will still function as normal. (Preflash time
can be adjusted to suit, from 1 to 10 seconds). By default pre-flashing is off.
LIGHTNING PROTECTION
All the CENTURION controllers have on board lightning protection. The protection
circuitry was designed in conjunction with the CSIR. Provided that the system has
been properly earthed the protection will significantly improve the resistance of the
system against lightning strikes.
Ancillary Equipment
PROTECTION BEAM (OPTIONAL, BUT RECOMMENDED)
An Infrared beam, or underground loop, across the gate entrance may be
connected to the controller as an additional safety feature. When a motor vehicle
activates the loop or beam the following occurs:
: If the gate is closing, it will immediately stop and reopen.
: If the transmitter or intercom gate release pushbutton is pressed while the beam
is broken, or the loop activated, the gate will remain open. The auto-close time will
restart its countdown.
: If the "AUTO-CLOSE" feature is selected, the gate will remain open while the
beam is broken or loop activated. If the beam or loop is cleared the gate will close
again only after the preset auto-close time has expired.
