B.Provide lighting control panels for control of the lighting in the three (3) gymnasiums.
C.Provide a lighting control panel UL listed for use for both normal utility power and life safety (generator loads) loads within a single enclosure. Providing separate lighting control panels (normal and life safety) is acceptable, provided the panels operate seamlessly together with the Integrated Automation Systems and also meet the remainder of these specifications.
D.Provide a networked system whereby any input to a lighting control panel (hard or soft, maintained or momentary) can control any output relay or group of relays in any lighting control panel.
E.Provide a lighting control system that does not require a computer to operate once programming and setup have been completed. Systems that allow remote programming thru a PC is allowed, but the system shall not rely on a computer to operate once the system is programmed and on-line.
Select paragraphs below if division 25 will be controlling the lighting through soft inputs to the lighting control system.
F.Integrated Automation will provide momentary dry contact closure points (one ON point and one OFF point) for each lighting relay. Provide software programming at each panel to accept the EMS momentary dry contact closures and to control the appropriate relay or combination of relays in the entire lighting control network.
G.Provide ON/OFF control of all lighting relays individually, plus a system-wide “Sweep-off function”. Refer to the lighting control panel schedules on the drawing.
H.Provide relays that adhere to the following minimum requirements:
1.Provide discrete relays, replaceable one-for one.
2.Relays mounted to circuit boards or that rely on circuit boards for line voltage current are not acceptable.
3.Provide relays rated for 150,000 MTBF life cycle at full load current rating. Relays alone must adhere to this rating and cannot rely on zero switching technology to meet this rating.
4.Provide 1-pole and 2-pole relays as called out in the schedules.
5.Provide HID rated relays for all relays.
6.Provide HP rated relays for relays called out to control line voltage motor loads.

e.Automatic photocell control/timer control of exterior lighting and day lighting zones.
5.Occupancy Sensors. Occupancy sensor inputs shall be wired directly to the soft switch inputs of the lighting control panels.
6.Toggle switches and Momentary Contact switches. Switches wired to the soft inputs of the lighting control panels will also be used to provide manual overrides from a central location.
7.Sweep off schedule. Provide scheduling of any relay or group of relays to automatically turn off at predetermined times of the day or night. Scheduling will be determined by the Owner.
8.Daylight sensors. Provide daylight sensor input to the lighting control equipment that automatically varies the lighting in the room or rooms. All adjustments to the levels, rate, delay, etc, must be performed at the lighting control panel through software, and not at the remote sensor.
B.Life Safety Operation
1.All life safety relays shall fail closed, and must revert to the closed state upon loss of normal utility power, regardless of the status of the life safety relay prior to the power outage. The relays shall remain in the closed state until normal power is restored, regardless of any inputs that may be “requesting” that the relay open.
2.After any utility power outage (momentary or long duration), all normal relays shall revert back to whatever state they were in prior to the normal power outage.
C.Power Supply – Battery backup
1.Provide sufficient battery backup of the lighting control system to ride through generator starting times and other power interruptions. Provide 5 minutes minimum for all panels and equipment on the entire Lighting Control System.
