Sample Scenario Application
An office building is used for the sample application illustrated in the Programming Record sheet
on the next page. In this application, the LP8 panel contains two relays controlling open office
space lighting. Two relays control hallways and common area lighting. Another relay controls
the branch circuits to individual office lighting, with Automatic Control Switches in those offices.
There is also a relay for exterior security lighting and two for parking lot lighting and signage.
The sample Programming Record Sheet on the next page summarizes the data required by the
Clock for each channel in our sample application.
Channel A is assigned a Manual ON/Sched OFF scenario for the open office areas. The lights
will be turned ON by occupants using a switch. They can be turned off by the occupant using
a switch or automatically per the time schedule. Overrides will be in effect if the occupant
manually turns lighting on at the switch during unoccupied times.
Channel B is assigned a Scheduled ON/Scheduled OFF scenario for corridors and common
areas. The lighting turns on and off per the times scheduled. Overrides will be in effect if the
occupant manually turns lighting on at a switch during unoccupied times.
Channel C is assigned an AS Manual On/Auto Off scenario for multiple private offices.
Occupants use the AS-100 switch to turn on the lights in their offices. During unoccupied times,
the LP8 panel periodically blinks the lights, starting a 5-minute delay off countdown at the AS-
100 switches. If no occupant overrides it, the AS switch will turn off the lights. The sweep off
scenario is repeated at the programmed sweep interval until the scheduled occupied time.
Channel D is assigned an Astro ON/OFF scenario for exterior security lighting. The on and off
times are based on the clock’s astronomical function which determines sunrise and sunset
according to geographical location. Note: A similar operation can be achieved by connecting an
exterior photocell to the LP8 and programming a Photocell On/Off scenario.
Channel E is assigned an Astro and Scheduled ON/OFF scenario for parking lot lighting and
exterior building lights. The time this lighting turns on is based on the clock’s astronomical
function as above, but the lights will turn off at a scheduled time. The lights will turn back on in
the early morning if it is scheduled to turn on and the astronomical function determines that it is
still dark. Note: A similar operation can be achieved by connecting an exterior photocell to the
LP8 and programming a Photo & Sched On/Off scenario.
