24 Way Transistor Output Board
ZP3AB-OP24 - 24 way programmable open collector
The Ziton ZP3AB-OP24 is one of a series of additional, auxiliary boards designed to extend the ZP3 panel standard range of input/output facilities. Boards are modular in design, and are mounted inside the ZP3 panel enclosure, by means of a ZP3-AC1 auxiliary chassis.
Up to three boards can be fitted into a Ziton ZP3 fire panel. They may be all of a single type, or any combination from the I/O module range. The addition of auxiliary boards can increase the panel outputs to a maximum of 72 all housed within the ZP3 enclosure.
Further output boards can be added to a system, accommodated in a remote control cabinet, usually located alongside the ZP3 panel. Various sized cabinets are available, designed to match the control panel enclosure. Each ZP3 fire panel has the ability to operate up to 896 outputs, of which 768 are programmable. The Ziton ZP3AB-OP24 offers 24 programmable, transistorised, open collector outputs. Designed to drive small current devices with resistive loads, each output is equipped with a jumper switch, which when removed reduces the outputs normal rating of 18 mA down to 8 mA to enable LED indicators to be directly connected. Power to operate modules can be provided internally from the control panel.
Each Ziton ZP3AB-OP24 24 way open collector output board is allocated an address by switch settings provided on the PCB. Once addressed the ZP3 system software automatically reserves the capacity of three separate addresses to enable all 24 outputs to be individually programmed, in the systems cause and effect software set up.
The operation of outputs is confirmed by LED indicators positioned in line with each wiring terminal. Power on and fault indicators are also provided on the PCB. Housed within the Ziton ZP3 panel, options can simply be added during panel manufacture to meet individual specifications, or subsequently fitted on site should a particular requirement become necessary during the life of the system.
