Nick, sorry I was so slow in coming back to this topic.
The unit below would indicate the shunt trip can be located in the machine room.
PACKAGE SOLUTIONS SIMPLIFY ELECTRICAL CODES AND STANDARDS FOR ELEVATOR SHUNT TRIP DISCONNECT
The BUSSMANNÂ® POWER MODULEâ„¢
package solution takes the confusion and headache out of designing and building shunt trip disconnect capabilities into an elevator power system. Special requirements surround the elevator disconnect because it interfaces with fire alarm systems for shut down. In one easy-to-install pack-age from Bussmann, you get a solution for all required codes and standards: ANSI/ASME A17.1 calls for shunt trip operation of the elevator disconnecting means so power is turned off before water from the elevator shaft sprinkler system is applied. NECÂ® 620-62 limits the selection to devices that are proven to selectively coordinate between the over current protective device in the elevator disconnect and ALL upstream devices.
NFPA 72 requires the fire safety signal interface with a single point electrical and mechanical tie-in.
POWER MODULE Switch
30 â€“ 400A,600Vac 3Ã˜
UL 98 Listed for 200,000A RMS short-circuit current rating
Shunt trip 120V
POWER MODULE Panel
400 â€“ 800A bus MLO and/or main switch
UL 67 Listed for 200,000A RMS short-circuit current rating
Feeder switches 30 â€“ 400A,600Vac accept Bussmann LPJ (amp) SP fuses
NECÂ® 110.9 requires high short-circuit current. The POWER MODULE meets all of these electrical codes and standards, plus reduces installation time and space requirements.
The POWER MODULE includes all the parts needed to interface with a fire alarm system in a UL Listed assembly:
Control circuit fuseblock
Fire alarm isolation relay
