Brief Introduction

The AutroSafe Self Verify™ Integrated Fire and Gas detection system

described in key words is as follows:

 Both the Fire Detectors as well as the Gas Detectors can be

connected to the same panel or system.

 All detectors are interactive addressable devices with intelligent

communication. Non-addressable detectors can be connected via

a 4-20mA interface.

 Field devices have a built-in calibrated self-test to verify and

confirm their ability to perform correctly. This can be considered as

supplemental to – and can be used instead of – manual testing and

inspection routines. Refer to Chapter 4.4.

 Flame and Gas Detectors can be connected to the AutroSafe

Panel by using a 2-wire loop structure (PowerLoop). The

PowerLoop provides both power to, as well as interactive

communication with the detectors. Studies have shown that the

Fire & Gas Detection Control System’s cable requirement can be

reduced with 30-60% by utilizing this concept as opposed to

conventional systems.

 AutroSafe SelfVerify™ IFG is a modular and distributed system

providing maximum flexibility. The AutroNet communication

facilitates the possibility to link cause and effect across panels

within the same AutroNet. In other words, any detector connected

to any panel can activate any output associated to any panel. Each

panel can have up to 12 custom AutroSafe I/O modules. Within the

limitations of the system, the system designer can freely select the

type and number of modules to be used.

 There are a number of versatile communication options available:

 Physical: Ethernet, RS-232. RS-422. RS-485. Al_Com loop,

AutroFieldBus, PowerLoop and either hardwired or fibre-optic

based AutroNet (Ethernet).

 Protocols: Modbus RTU Slave or Master, Modbus TCP/IP

Slave or Master, ESPA 4.4.4. and AutroCom (Autronica’s

proprietary protocol).
