INSTRUCTION DATA SHEET
This product must be earthed in accordance with local safety regulations.
The Control Panel leaves the factory configured for the supply voltage stated on the customers order.
Standard voltage and frequency range is:-
AC Mains Powered 85 to 264 VAC 40 to 400 Hz
DC Low Voltage Powered 18 to 30V DC
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 0 C and 40 C. If stored at low temperatures
and then brought into a warmer environment, condensation may form on some components. In such a
situation , this condensation should be allowed to evaporate prior to use of the equipment. If stored at
high temperature, care should be taken to ensure that humidity condensation does not enter critical
electrical components, for example the power connector.
The Control Panel is designed to operate within specification for ambient temperature between 5 C
and 40 C, relative humidity up to 90% ( non-condensing ).
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..

It is imperative to use cabling which suits
the environment in which the T700 and its
sensors are to be used. The following is intended
as a guide.
Fit 1.5mm SQ cable for analogue systems
Fit 2.5mm SQ cable for addressable systems
Use
Pirelli LSX type cable for office/light commercial
un-zoned installations
Steel Wire Armored or CY cable for medium/heavy
industrial un-zoned installations
Mineral Insulated Pyro cable for all hazardous
area zoned installations.
Note in all cases the T700 Panel must be installed outside
of any hazardous area and must be supplied via
a fused spur.

The Tocsin 700 series gas detector control panels are designed to be as flexible in operation as
possible. The system software allows the owner/installer to configure the following functions:-
Configure input type, not only the selection of pre-programmed input gases but also the option
to define an input type and scale the incoming 4-20mA signal to match. For example,
pressure, temperature, distance etc
Decide alarm levels for each input and decide, rising,falling or latching alarms and which relay
to asign to which inputs to allow, zoning etc
Logical naming of inputs, for example 'boiler room 1'
Set the display scan rate
Zero and calibrate each channel from the control panel.
In addition the Tocsin 700 control panel can be 'hooked up' to a PC or PALM device via its serial
programming link to allow system configuration using Oliver IGD software. This allows not only pre-
configuration of the panel prior to commissioning but also a record of how the system was set up.
+Always refer to the shipping manifest and test schedule for confirmation of the shipped
configuration.

Accepting and Reseting Alarms
For most of its operating life the Tocsin 700 control panel and associated sensors will monitor for
whichever hazard it is configured for. The only requirement from the plant operator is to have the
system regularly calibrated, typically every 3 or 6 months depending on the nature of the gas
hazard. This section describes what happens at the control panel should the system detect a hazard
and go into alarm and how to accept the alarm and reset the control panel.

Step 1. The panel detects a gas hazard
Step 2. Operator Accepts The Alarms
Panel indicates which channel is in alarm
Panel indicates which alarm level has tripped
Panel indicates how many alarms in total have tripped
Relay outputs will activate dependant on the
system configuration
Alarm outputs (beacons and sounders) are active
if fitted.
The user programmed description for the sensor is displayed
Pressing the jog wheel will accept the indicated alarm. If there is more than one alarm tripped then
the next alarm is indicated on the display. Note that the total number of active alarms is indicated in
the top right of the display.
Once all alarms have been accepted the sounder output from the panel is de-activated, if a sounder
has been fitted it will silence. The relay outputs associated with the active alarms will still be
energised until the gas hazard has been cleared and the panel reset.
Once all active alarms have been accepted the display will read as follows:
Pressing the jog wheel at this stage will reset the system. This de-activates any energised alarm relays
depending on the panel user alarm programming and the 'beacon' output. If the gas hazard is still present
then the panel will go back into its alarm state after a few seconds otherwise the system reverts to normal
operation.
WARNING
It is important to have a site health and safety
response in place in the event of alarm activation.
Gas detection systems are an indication that a
problem may exist but should not be relied on as a
failsafe system. .
