Page 4: Where To Install A Gas Detector
Where to Install a Gas Detector Like all gas detectors, the best place to Gas Sense detector install a will depend on the target gas. In general, for gasses lighter than air it will be installed 30-50cm from the Lighter Gases ceiling. -
Page 5: When To Test The Detector
When to Test the Detector Determining the frequency of gas detector testing will depend on a suitable risk analysis of the protected area. For example if the consequences of a leak are small, then checks every 6 months or a year may be acceptable. If the consequences of a leak are severe, then it is good practice to check the detector calibration regularly. -

Toxic Detector Specifications In order to easily identify each toxic gas detectors, each gas has it’s own colour coded label. Gas Type Model Number ZS-H2S/500 ZS-H2S/200 ZS-H2S/100 ZS-NH3/1000 ZS-NH3/100 ZS-NO2/20 ZS-CO/300 ZS-CL2/20 Part Number 47-522 47-521 47-520 47-531 47-530 47-540... -
Page 9: Combustible Detector Specification
Combustible Detector Specification Alkanes & Aromitics For combustible gases, the Zeta Gas Sense detector uses the same sensor element for all gas types. The detector is then calibrated specifically for that gas.

Page 11: Zeta Sense Gas Control Panel
Zeta Sense Gas Control Panel The Zeta Gas Sense Controller (ZSC100) has been designed to monitor and control 48 gas sense detectors. In addition to this, it can run Zeta addressable I/O units, and the range of Zeta addressable sounders. It has a 4 x 40 character LCD display which helps display all the required device information on the screen. -
Page 12: Zeta Addressable Input-Ouput Units
Zeta Addressable Input-Ouput Units The Zeta addressable input output units (ZIOU and ZIOU/230) are used to interface external equipment to any Zeta addressable fire alarm system. It has a switch monitoring input with a 47K End-of-Line resistor and volt free SELV relay output. There are two versions available, one for switching low voltage (ZIOU) and the other for switching mains (ZIOU/230). -
Page 13: Maxitone Addressable Sounder
Maxitone Addressable Sounder The Maxitone addressable Sounder is a large horn sounder suitable for many applications. It can be used on any panel using Zeta Addressable Protocol. It is available as a sounder only in red or white, or as a combined sounder flasher in transparent red. -

Page 15: Calibration And Bump Testing
Calibration and Bump Testing Gas detectors should be functionally tested regularly to ensure their correct operation. This is referred to as bump testing. To bump test a Zeta Gas Sense detector, fit the Calibration cap to the stainless steel filter housing. Then take a test Cylinder with the appropriate gas type & concentration. - Page 16 Available now from: Tel: +44 (0) 1792 455 175 Detection House Fax: +44 (0) 1792 455 176 72-78 Morfa Road Swansea E-mail: info@zetaalarmsystems.com SA1 2EN Web: www.zetaalarmsystems.com United Kingdom...
