MKII Soft & Hard Addressable Fire Alarm System

As a company who invests heavily in the development of our products we made a decision in 2011 to design a brand new addressable protocol which we have named the Fyreye MKII Protocol.

While the existing protocol has served Zeta Alarm Systems well for many years, it is a dated protocol, which has several limitations. The new Fyreye MKII Protocol has been designed to be flexible, with plenty of room for future expansion. This will allow us to continue developing innovative new products, without being restricted by protocol limitations imposed by the existing protocol.

A weak point of the existing protocol is error checking. We have taken the opportunity to increase the error checking capability eight fold. While this level of error protection could be considered overkill, we believe that the robustness this gives, will allow Fyreye MKII Protocol systems to function error free, even under extreme conditions.

Features Of Fyreye MKII Protocol

• 250 devices per loop
• 255 types of devices
• Up to 3 analogue value readings
• Read optical detector drift compensation value
• Manufacturing date can be stored in each addressable device
• Display battery level/signal strength of wireless devices
• Improved sounder synchronisation
• Quick start/stop loop powered sounders
• Panels can trigger sounder with alert tone, alarm tone or emergency tone
• Alarm tone selection from control panel (choice of 16 tones - 11 defined, 5 for future use)
• Panel can read the device’s software version
• 8 bit checksum for reliable communication
• All devices can be softly addressed via a hand held programming tool
• Approximately 50% of protocol commands are free for future expansion and development

Wireless Fire Alarm Systems

Wireless technology is now an everyday part of our lives, both at home and in the workplace - having radically changed the way we work and communicate. Parallel advances in battery technology and electronic components that operate at much lower voltages and power levels have helped to make this possible.

Safety critical installations such as fire detection and alarm systems often require large numbers of field devices to be fitted which, for reasons of integrity and lifetime cost of ownership, are still preferred, specified and will remain as hardwired types for the foreseeable future. It is therefore clear that there is a place for both types of technology 'wired' and 'wireless' when designing and specifying a fire detection system. Wired devices should be used where cables are easy and cost effective to install, and wireless devices should be used where the installation of cables would be expensive, time consuming, impractical or just impossible.

• Easy to install, commission and operate
• Complete range of filed devices available
• Up to 30 field devices per radio interface
• Up to 3 year battery life

Aspiration Detection Systems

The FyreSense Aspirating Smoke Detection System uses fans to draw air from the protected area via pipes and sampling holes. The air is then passed through a high sensitivity detector. FyreSense has many advantages over ceiling mounted point detectors

Special Features

• Higher sensitivity
• Lower installation and maintenance costs
• The detectors can be situated away from harsh environments
• The air can be filtered or heated before reaching the detectors
• Easier to maintain in areas such as lift shafts, ceiling voids or under floor boards
• Ideal for use where aesthetics are important or where the application must be vandal proof
• Better performance where there are high ceilings, high air speeds or smoke stratification

Addressable Fire Alarm Systems

The Premier Quatro is the new 4 loop analogue addressable fire alarm panel from Zeta Alarm Systems

Linear Heat Detection Systems

The Zeta Heat tracer system consists of a control module, and a special 4 core heat tracer cable. The cable has 4 cores, 2 are covered with negative temperature co-efficient (NTC) material, the other 2 have normal PVC insulation. The cores are twisted together and protected by an outer sheath of high temperature flame retardent PVC insulation.

The Primary mechanism of heat (fire) detection is that the dielectric between the 2 NTC cores is monitored for any change, and compared to the 2 PVC cores.
