4 Way Output
  • General
  • Feature
  • Specification
The 4-way programmable relay card is a compact remote I/O device for the ZX series intelligent multi protocol fire alarm control panels. This device, along with other remote I/O devices, the repeater units and the external printer provide a compllete range or peripheral devices to further enhance the functionality and expandability of the ZX series systems. The 4-way relay card consists of 4 relay outputs built on a single printed circuit board. Each output relay provides single pole double throw (SPDT) switching action for other locally powered equipment. The form C relay contacts are designed to switch resistive loads of up to 1A/24V ac/dc. The 4-way relay card connects to the ZX series control panels via the RS485 peripheral port (Port D). An RS485 communication card must be fitted in the ZX series control panel for that purpose.
• Provides four individually programmable relay outputs • Compatible with ZX series intelligent multi protocol fire alarm control panels • RS485 communication • Connects to the peripheral bus (Port D) on the fire alarm panel • Up to 31 on one peripheral bus • Easy DIP switch addressing • Normal, delayed or double-knock operation options • LED relay status indication • Contact rating: 1A at 24V AC/DC
