Hey Guys, I'm piping an alarm circuit in an elevator mechanical room. There is an existing cable tray with 120 volt circuits in it with no separation barrier. The alarm cable is not shielded. Is this code compliant? TIA
 
What type of wiring method is the 120 circuit? If it’s a chapter 3 wiring method, MC, AC, then no seperation/barrier is required
