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 230V AC (176 to 264V AC) 47 to 63 Hz
Switch Selection Option 110V AC (88 to 132V AC) 47 to 63Hz
DC Low Voltage Powered 18 to 30V DC
NOTE: Operation on an incorrectly selected supply voltage will damage the controller
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 55 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 supply. The Control Panel is designed to operate within
specification for ambient temperature between 0 C and 55 C, relative humidity up to 95% ( non-condensing ).
On installation alarms will need to be configured to signal when monitored gas levels have breached safe limits. The
control panel will be shipped in a semi-configured state which must be checked and configured during commissioning to
match the applications cause and effect requirements. Failure to do so will result in an ineffective system.

Control panels are usually shipped pre-configured with a basic alarm strategy. Before installation check the
documentation provided to ensure the programmed cause and effect matches the site requirement. If it does
not then the system will need to be re-programmed by the installer using the embedded panel software or
PC based T700 setup software.
When first powering systems which include an IGD battery backup the batteries MUST be connected first for
correct operation. During initial startup the panel software will check the battery condition, if mains power is
applied first then the batteries cannot be functionally checked and the panel will report an error.

In all cases switched loads should have appropriate EMC protection as indicated in the diagram above.
Loads should be fused. DC inductive loads should not be powered from the controller PSU. Inductive
loads such as solenoids or motors can have high in-rush currents well above the steady state current
indicated on data sheets. These high in-rush currents can interfere with the correct operation of the
controller and so powering from the control panel is to be avoided.
Page 18 of 52
Powering Third Party Devices
In general third party devices should only be switched and NOT powered from the
Tocsin 700, (with the exception of beacons and sounders).
The Tocsin 700 controller has been extensively third party tested to ensure electrical
safety and EMC compliance in a number of installation formats.
Connecting third party devices which may place unknown power demands on the Tocsin
700 can result in damage and/or unintended operation and so is NOT recommended.
The requirement to power gas shut off solenoid valves is common and so has been
tested. The following tables and wiring arrangement will allow a suitable solenoid to
operate correctly from the control panel.
Note this connection is
direct from the 700
PSU. Incorrect
connection can
damage the 700 and
power supply. Check
polarity before
powering

an alarm
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 1' (max 8 characters)
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 preconfiguration 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.
Page 20 of 52
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
Panel indicates which channel is in alarm
Panel indicates which alarm level has tripped
Panel indicates how many alarms in total have tripped
CH1 AL 1 TOTAL 2

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
Step 2. Operator Accepts The Alarms
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:
WARNING
CH1 AL 1 TOTAL 2 OF 4
CH1 AL 1
It is important to have a site health and safety
PRESS RESET ALL
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
f a i l s a f e s y s t e m . .
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 it will not be possible to reset the alarm.

The menu system is accessed by firstly selecting a channel. This is done by rotating the Jog Wheel.
Clockwise increases the channel indicated. Anti clockwise decreases the channel indicated. When the
switch is rotated the back light illuminates and the unit stops it's auto scrolling function. If no channel is
selected or if the button is not rotated within a minute then the unit returns to it's normal auto scrolling
mode. In auto scrolling mode each channel fitted to the control panel is sequentially displayed for a
fixed time period.
To select a channel to work on the Jog Wheel is pressed. This takes the user into the main menu.

These outputs start their numbering from 4201. Up to 32
addressable relay output nodes can be added to either
addressable cable 1 or 2 (C1,C2).
This example shows an alarm set once 50ppm is exceeded
on channel 01. The relay activated if this occurs is on the
addressable highway at address 4201 connected to port 1 (C1).
The alarm is Rising and Latching in operation and so must be
manually reset at the Tocsin 700 panel (RIS&L). If the T700 jog
wheel is pressed the alarm will Mute (De-activate) as the action
is set to M.

5.8 Common Alarms
The common alarm menu provides another method to
01 FROM =1 TO =1
AL1 RELAY = 0
When using common alarms there are some restrictions to bear in mind when planning both the
layout of the channels and alarms:
activate alarm outputs. The menu option provides a
method to ‘group’ together channel alarms to a common
alarm output.
As an example if channels 1 to 6 on the control panel all
need to activate a beacon sounder on first alarm: then
this is simpler to set using the common alarms menu
rather than programming on each channel alarm.
This also free’s up the channel alarms for other outputs.
1: Common alarms work best with consecutive channels so if there is a requirement for a common
alarm output to work with a number of detectors in an area, make sure the detectors are on
consecutive channels.
2: If you use a relay output on a common alarm DON'T also use that relay on a normal channel
alarm. doing so runs the risk that a channel in the common alarm group can be trying to ‘set’ a relay
whilst an individual normal channel alarm can be trying to reset the same relay. This can result in
unpredictable alarm operation and is to be avoided.
3: There are 16 common alarms
4: If using addressable relay outputs or nodes, these must be on Cable Highway 1
Programming Example
Common alarm number 3
03 FROM =1 TO =6
AL1 RELAY = 4219
From channel 1 to channel 6 any AL1 on these channels activates addressable relay 4219

Analogue channels must be set up manually. The control panel accepts input from any 4-20mA device,
not necessarily gas detectors. For flexibility the channel setup function allows the gas type, range and
units to be configured. Most standard gas types, ranges and units can be selected from the preconfigured lists. However if the required gas type, range or units are not present on the preprogrammed lists then up to four user configurable types can be added. Adding user types is detailed
later in this manual. Note that channel setups can be copied to speed set up in a similar manner to the
way alarm setups are copied.

The FIND Command
If addressable gas detectors are cabled to either port 1 or 2 of the control panel then the FIND
command can be used to automatically install these detectors onto the panel. Note this option is usually
only run the first time detectors are connected and will already have been run if factory configuration
has been requested and undertaken. Running the FIND command again will overwrite any previously
stored information. This will include any alarm level set up as a newly installed detector will have default
alarm levels set automatically as part of the FIND function.

USING THE 485RPT MODULE TO SPLIT THE MAIN DATA HIGHWAY
In some circumstances more than one data highway may be required as well as a host Modbus
connection. This can be achieved by fitting 485RPT modules to the main highway port. If this is
to be implemented then one 485RPT module will be required per extra highway. The Tocsin 700
operates in the normal manner but it should be noted that there is still a limitation of 32 devices.

Integrated Battery Backup
The standard i700 is shipped with a 1.2AH Battery Backup Module
The battery is shipped separate from the control panel. Locate the battery in the panel once it is
mounted as indicated in the overview diagram. The batteries are shipped ready charged for
operation. Connect the battery to the charge management PCB with the cable provided
If required an additional 1.2AH battery pack can be fitted. This is supplied with a specific IGD
cable set to add the battery in parallel to the existing battery. Third party units must not be used.

Test Points
The Single Pole relay changes state when mains power is
lost and the Tocsin 700 runs on the battery pack. It can
therefore be used to remotely indicate mains power loss.
The relay is rated at 7A 250V Non Inductive. Note the
relay is powered in normal operation and opens on alarm
or power loss.
Page 46 of 52
Front Panel Status LED’s
Mounted on the front panel of the battery backup module are two status LED’s. The Following
table indicates their operation.
The Mains power LED will be on when the unit
is operating from 110/230V AC. In this mode
the battery backup module is inactive and
being charged if required. The LED’s will
indicate the charge level as the battery is
being re-charged.
If the Mains power LED is off, then the battery
pack is active and providing backup power to
the TOCSIN 700 controller and associated
detectors. In this mode of operation the charge
level indicator LED’s indicate remaining
battery power.
The battery pack will automatically switch into
operation once the incoming 24V DC power
rail drops below 22V.
Once battery power drops below 20V DC the
controller determines that the battery pack is
exhausted and power to the TOCSIN 700
controller will be turned off.

Note that the status LED’s take up to one
minute to show correct status.
Both LED’s will flash at start up as the
controller makes an assessment of the
battery and mains power status.
As soon as mains power is restored the
controller will start re-charging the battery
pack. The charge status will be indicated on
the charge LED’s. Typical re-charge time from
flat will be approximately 5 hours.

PCB DIP Switch Selection.
The DIP switches fitted to the charge control PCB, control
some of the operational features of the controller as
follows:
By default all switches are in the OFF position.
DIP switch 1 is used to set battery size, set to OFF for
1.2Ah batteries. Set to on for 7Ah batteries
DIP switch 2 sets the charge rate. set to OFF for max
300mA charge, this is the default max. Set to ON for
100mA charge, this setting is typically used in conjunction
with the TOC-625 controller fitted with more than 4
detectors to limit the battery charge rate due to the smaller
size of the TOC-625 PSU.
Note that the DIP switch setting is only read at power up.
The system must be powered on and off (batteries
disconnected) before the new setting takes effect.
For a new installation.

1. Connect the batteries allow system to power up on battery power
2. Switch on the mains power to the control panel
During this process observe the LED status and see the battery charge status
then the switch over from battery power only to mains and battery charge.

Assessing A typical System For Battery Life
Use a table similar to the one indicated below to make an assessment of the system power
requirement.
System Component Alarm Mode Current Quantity Totals
Tocsin 700 0.25Amps 1 0.25Amps
Tocsin 920 0.5Amps NA NA
Tocsin 102 IR HC Detector 0.05Amps 4 0.2Amps
Tocsin 102 Pellistor HC Detector 0.13Amps 0 0
Tocsin 102 Toxic Gas Detector 0.02Amps 5 0.1Amps
Audible Alarm (Typical Example)** 0.12A 0 0
Visual Alarm (Typical Example)** 0.15A 1 0.15Amps
Additional Relay Units (8 Per Card)* 0.01A/Relay 0 0
Total System Current 0.7 Amps
The batteries used are 1.2AH units so using the previously indicated de-rating factors the
expected battery life will be as follows:-
Expected Operating Battery Life= Battery Capacity x de-Rating Factor
Total System Current
= 1.2AH x 0.75 = 1.3 Hours
0.7A
Note that in this example whilst the de-rating factor indicated was just 10% of battery capacity the
next de-rating factor up was chosen.
Values indicated in the system component table are those for alarm condition to take account of
the greatest possible current draw.
Page 49 of 52
Assessing Battery Life
Battery back up life is dependant on the power consumption of the main control panel and the
consumption of the detectors connected to it. The following table indicates how to assess the likely
back up period for a system. Other factors can have an influence particularly how many
charge/discharge cycles the batteries have been subjected to and the age of the batteries. It is
recommended that batteries are replaced every two years as a matter of course.

Battery De-Rating Factors
It is normal practice to de-rate battery performance with increasing current draw. The
following table indicates the de-rating factors recommended to be applied in
calculating the time any given system will run on battery battery power.
