Supports Operational Temperature Range of -40 °C to 70 °C (-40 °F to 158°F).
MS-FEC2621-0: 17-Point FEC with integral display and pushbutton user interface.
Smoke Control Models:
MS-FEC2611-0U
MS-FEC2621-0U
24 VAC (nominal, 20 VAC minimum/30 VAC maximum), 50/60 Hz, power supply Class 2
(North America), Safety Extra-Low Voltage (SELV) (Europe)
14 VA maximum for FEC2611 only
20 VA maximum for FEC2621 (with integral display) only
Note: VA rating does not include any power supplied to the peripheral devices
connected to Binary Outputs (BOs) or Configurable Outputs (COs), which can
consume up to 12 VA for each BO or CO; for a possible total consumption of an
additional 84 VA (maximum).
