PROLOGUE

Gas-Pro Overview

Thank you for purchasing the new Gas-Pro. At Crowcon we recognise the need for reliable and

robust personal monitors which are sized to be worn and simple to use.

Gas-Pro is a portable monitor capable of detecting up to 5 gases in a compact and wearable design

featuring an optional internal pump. Focused on users and eet managers alike, Gas-Pro offers

application focused solutions giving greater operating time and reduced set up time.

Gas-Pro is classied for use in hazardous areas and gives loud and bright audible and visual alarm

indications as well as a vibrate alert. The top mount display is backlit for ease of use, and the simple

single button solution makes using and training quick and easy.

This manual covers the extra functions added for the military version of Gas-Pro, listed below:-

• The addition of Mute modes.

• Normal Mode (vibrator, LEDs and sounder active).

• Vibrator only mode (LEDs and sounder inactive).

• Full Mute mode (vibrator, LEDs and sounder inactive).

• Addition of Mute status to the main gas screen.

• Change of the user menu scheme so that Mute modes can be changed and accessed from the

top level.

In full mute mode the only remaining indication of hazardous gas is via the LCD screen.

CAUTION

A personal gas detector is a safety device to provide warnings about dangerous or potentially

dangerous gas hazards. Mute modes undermine some of the safety outputs thereby limiting the

warnings given to the user.

• Use Mute modes sparingly and re-enable outputs as and when it may be safe to do so.

• Be extra vigilant of the alarm indications on the LCD.

The device’s start up routine tests the audio and visual outputs of the device regardless of

selected ‘mute mode’, as safe practice. The pre-selected ‘mute mode’ will take effect again

after the start-up routine has completed.

Safety Information

• Gas-Pro is a hazardous area certied gas detector and as such must be operated and

maintained in strict accordance with the instructions, warnings and label information included in

the manual. Gas-Pro must be operated within the limitations stated.

• Read and understand all instructions in the operation section of the manual prior to use.

• Before use ensure that the equipment is in good condition, the enclosure is intact has not been

damaged in any way.

• If there is any damage to the equipment do not use, contact your local ofce or agent for repair/

replacement.

• Do not disassemble or substitute components as this may impair intrinsic safety and invalidate

safety certication.

• Only genuine replacement parts must be used; substitute components may invalidate

certication and warranty of the Gas-Pro and accessories, reference “Service and

Maintenance” section of the manual for details.

• No live maintenance is permissible.

• Observe all warnings and instructions marked on the unit and within the manual.

• Observe site health and safety procedures for gases being monitored and evacuation procedures.

• Understand the screen display and alarm warnings prior to use.

• If this product is not working properly, read the troubleshooting guide and/or contact your local

ofce or agent, for details reference the ‘Contacts’ section of the manual (see page 55).

• Ensure maintenance, service and calibration is carried out in accordance with the procedures in

the manual and only by trained personnel.

• Gas-Pro must not be charged or have communication to the device, at ambient temperatures

outside of the temperature range 0°C to 40°C.

• Only connect to Gas-Pro in a safe area for charging or communications.

• Charging cable assemblies, whilst nominally providing a voltage of 6.5V, must not exceed a

voltage of 9.1V as this may impair intrinsic safety and invalidate safety certication (Um=9.1V).

• Communication cable assemblies, whilst nominally operating at a voltage of 3.0V TTL, must not

exceed a voltage of 9.1V as this may impair intrinsic safety and invalidate safety certication

(Um=9.1V).

• The devices are intended for use in normal atmospheric conditions of temperature –20 °C to

+55 °C; pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and air with normal oxygen content,

typically 21 % v/v (volume/volume).
