final bid specs 09328.pdf - Freese and Nichols, Inc.

F. A dedicated photocell input shall allow connection of a remote analog photocell. The ON/OFF
set points and dead band settings for photocell operation shall be adjustable through the
program and not require adjustments at the remote photocell location. The controller shall
provide for setting individual photocell set points for all relays.
G. Relays shall be single-pole 20A rated for 10,000A SCCR or 2-pole 30A rated as scheduled.
Each controller shall have provision for a maximum of eight single-pole relays or four singlepole
and two 2-pole relays. While in operation, the current status of each relay shall be
displayed and visible to the user with the enclosure access door closed. A service override
switch shall be located within the enclosure and provide positive ON or OFF override of all
relays.
H. The enclosure shall be NEMA 1 rated construction with a hinged locking door and shall
provide separate compartments for line and low voltages. A screw-down cover shall further
restrict access to the high voltage compartment.
I. Lighting controller shall be SwitchPak relay panel manufactured by Synergy Lighting Controls
or approved equal.
2.03 OCCUPANCY SENSORS
