Brief Introduction
The Tocsin 635 series control panels use the latest technology 2-wire addressable highways to
control gas detectors and associated accessories. Providing an extremely flexible and low cost
solution.
Main Features
635 Series
Up to 32 Detector Nodes
Jog Wheel Interface
RGB Backlit Display
Service & Maintenance
It is recommended that control panels and all connected detectors are commissioned upon
installation and serviced every 6 months by an IGD trained technician. IGD can offer full training to
enable your staff to do the servicing or offer a competitive service from our fleet of service
engineers.
Warnings and Performance Statements
This control panel is not to be located in a classified Ex area, devices installed in an Ex area
can be connected to this unit but shall be protected with one of the types of protection
listed in IEC 60079-0 corresponding to their own category.
We recommend users read the
procedures described in IEC 60079-29-2 for reference.
This product must be earthed in accordance with local safety regulations. A switch or circuit
breaker must be included in the installation; it must be suitably located; easily reached and it must
be marked as the disconnect device for the equipment.
The Control Panel leaves the factory configured for the supply voltage stated on the customers order.
Standard options are indicated in the basic specifications on page 4
Should the control panel be used in conjunction with portable generating equipment, care should be
taken to ensure that the electrical supply is within the tolerance band described above.

The control panel may be stored at temperatures between -25 C and 60 C. If stored at low
temperatures and then brought into a warmer environment care should be taken to ensure that
condensation does not form or enter critical electrical components, for example the power supply.
Allow 24 hours to stabilise extremes of temperature.
o
The Control Panel is designed to operate within specification for ambient temperature between -20 C
o
and 55 C, relative humidity up to 90% ( non-condensing ). Sensor specifications may differ.
Do not use a Control Panel for protection applications that has not been calibrated. If calibration seals
are missing from the control panel or have been tampered with or broken, then the control panel must
be re-calibrated and sealed by a trained engineer.
Substances and interfering gases can cause adverse effects on the performance or electrical safety of
the gas detection systems. Care should be taken to limit exposure to these poisoning substances, for
further advice and information contact head office
The response time of the entire system is determined by the time of response of all the parts of the
equipment within the gas detection system.
The relationship between the output signal and the gas concentration is linear, the control panel
interprets the signal and the gas level is displayed on the RGB backlit display. IGD hold evidence of
this linear performance which is available upon request.
