The Protec 6000/APZA is a zone alarm interface which allows the 6000 series intelligent addressable loop to interface to a zone of conventional devices and a conventional sounder circuit.
This interface is ideally suited for small conventional fire detection to be fully integrated with Protec Intelligent addressable systems. The 6000/APZA is powered using an external EN54 Part 4 power supply. It can support up to 20 Protec conventional (3000PLUS) detectors.
The zone end of line is selectable using the on board DIL switch and can be programmed to resistive or capacitive as per the requirement of BS5939-1. The sounder circuit is monitored for open and short circuit faults and has 1A current drive capability.
The interface has an inbuilt loop short circuit isolator fitted as standard.
