Autocall Circuit Protection; Model A2081-9044 Overvoltage Protector

UL ULC CSFM Listed Accessories Protection Model A2081 9044 Overvoltage Protector Listed as an Overvoltage Protector to ULC S527 Control Units for Fire specifically for protection of fire alarm circuits DC power 200 mA maximum Data communications Local energy city circuit connections Rugged epoxy encapsulated package Refer to A2081 9044 Overvoltage Protector Application Reference for details stages of protection include Line to Line protection and Line to Earth protection Reference Listed as an Overvoltage Protector to UL 864 Control Units and for Fire Alarm Systems Systems 70 Listed as an Isolated Loop Circuit Protector to UL 497B Protectors for Communications and Fire Alarm Circuits Compatible with the requirements of the National Electrical Code Protection transients caused by lightning or by disturbances on high power lines can cause damage to low voltage fire alarm circuits application of A2081 9044 Overvoltage Protectors can minimize energy from those electrical transients to a level that can be safely by the circuits requiring protection This protection is most when placed at the locations where the circuits leave and enter A2081 9044 Overvoltage Protector provides multiple stages of against electrical transients The small package size allows it be easily mounted at the location that achieves maximum protection Wiring Requirements alarm system wiring that is run external to the building and is by A2081 9044 Overvoltage Protectors shall be installed accordance with the individual system component s installation including properly grounded twisted and shielded wire and observance of the following precautions To ensure optimized protection the A2081 9044 Overvoltage shall be located as close as possible to the point at which the leave or enter the buildings and installed in dedicated metallic boxes distance is limited to one contiguous property The total wire length is determined by the individual application s limit as specified with overvoltage protectors but must not 3270 ft 1 km grounding conductor shall be 12 AWG with a maximum length of ft 8.5 m run in as straight a line as possible and connected to the grounding electrode
