UL864 Specific Considerations
Wiring to and from the device shall be through power-limited circuits.
Use only Core Components transformer, Model No. 120-024-100-2TF-CB, by Lectro
Components Inc. to power the device. (Delta Part # 440008)
Use only UL Listed Class 2 Power Supplies for auxiliary field devices.
Use only UL Recognized Ethernet Switch, 571-580, by Siemens for Smoke Control Systems
that utilize Ethernet communications.
Impedance value for which ground faults are detected is zero ohms.
Cautions or Warnings
This controller is an Electro-statically sensitive device. Proper ESD protection (ground strap)
should be used when installing this product so that damage to the product does not occur.
Equipment damage or loss of data may occur if these procedures are not followed as
specified.
Installations requiring CE conformance
: All wiring for CE rated products must use an extra
low voltage (SELV) or protective extra low voltage (PELV) transformer. Use safety-isolating
transformers, (Class II transformer) per EN61558. The transformer must be rated for 100%
duty cycle.
