Q: How many Chexit devices will the PS 914 operate?
A: Chexit devices shipped after 8-24-2015 with motor driven:

  • You can power up to four Chexit devices per PS914 power supply.
  • 0-200' run wire, use #18 gauge.
  • 0-500' run wire, use # 14 gauge.

    Chexit devices shipped prior to 8-24-2015 with solenoid driven:

  • You can power up to four Chexit devices per PS914 power supply on low traffic doors.
  • 0-100' run wire, use #14 gauge.
  • 0-200' run wire, use #12 gauge.
  • Q: Can 240 VAC be applied to the PS900 power supply?
    A: The standard PS900 series power supplies can be powered with 120-240 VAC.
    Q: What would make the PS914-2RS cycle on and off?
    A: Followings could cause the PS914-2RS power supply to cycle on and off:
  • Wrong gauge wire or run distance from power supply to the EL device. Click HERE for wiring requirements.
