option with requirements.
…………Signal representing the flow of extinguishing agent to indicate the released
condition. EN12094-1 Section 4.18 option with requirements.
…………Monitoring of the status of components by way of a low pressure switch input.
EN12094-1 Section 4.19 option with requirements.
………….Emergency hold device to enable the extinguishing delay time to be
extended. EN12094-1 Section 4.20 option with requirements.
………….Contro l of flooding time to deactivate the releasing output after a set period of
time. EN12094-1 Section 4.21 option with requirements.
…………Manual only mode to disable the release of Extinguishing via
automatic detection devices. EN12094-1 Section 4.23 option with requirements.
…………Triggering of equipment outside the system by way of first and
second stage contacts, extract fan output etc. EN12094-1 Section 4.26 option with
requirements.
…………Activation of alarm devices with different signals to indicate pre-
discharge and released warnings using d ifferent sounds. EN12094-1 Section 4.30 option with
requirements.
……….Emergency Abort device to inhibi t the extinguishing signal until the emergency abort
device has been deactivated and the panel has been reset. EN12094-1 Section 4.27 option with
requirements.

2 Safety
Suppliers of articles for use at work are required under section 6 of the Health and Safety at
Work act 1974 to ensure as reasonably as is practical that the article will be safe and without
risk to health when properly used.
An article is not regarded as properly used if it is used ‘without regard to any relevant
information or advice’ relating to its use made available by the supplier.
This product should be installed, commissioned and maintained by trained service personnel
in accordance with the following:
(i) IEE regulations for electrical equipment in buildings
(ii) Codes of practice
(iii) Statutory requirements
(iv) Any instructions specifically advised by the manufacturer
According to the provisions of the Act you are therefore requested to take such steps as are
necessary to ensure that you make any appropriate information about this product available
to anyone concerned with its use.
This equipment is designed to operate from 230V 50Hz mains supplies and is of class 1
construction. As such it must be connected to a protective earth conductor in the fixed wiring
of the installation and a readily accessible double pole disconnect device meeting the
requirements of EN60950/IEC950 which disconnects live and neutral simultaneously shall be
incorporated in the fixed wiring. Switch disconnect devices such as MK Sentry 63A or similar
are suitable for this.
WARNING:
adequately bonded to the protective earth will render the equipment unsafe.
This control panel is environmental class A and is designed for indoor use only at
temperatures between -5
95%.
The IP rating for the enclosure is IP30.
Operation outside of these limits may render the equipment unsafe.
Failure to ensure that all conductive accessible parts of this equipment are
0
C (+/- 3) and +400C (+/- 2) and with a maximum relative humidity of
3 Mounting
The ECU should be mounted on a dry, flat surface, at eye height to the displays and in a level
position such that the enclosure is not distorted.
Screws or bolts of a minimum of 5mm diameter must be used to mount the enclosure in all
four mounting positions.
It should be positioned in an accessible place as agreed with the end user.
Suitable fixings should be used at all fixing points such that the unit is securely mounted and
is not liable to move once fixed.
The ECU should not be mounted in another enclosure or near sources of excessive heat.
Cables should be connected using suitable cable glands fitted to the knockouts provided. If
additional cable entry points are required, all swarf and debris caused by drilling of additional
cable entries must be cleared before power is applied to the panel.
TM206 5 of 35 Issue 1.0
Cables should not be installed in the bottom of the enclosure. This space must be kept free
for batteries

6 Removing the equipment chassis
Open the control panel lid using the two 801 lock key.
Before the chassis can be removed it will be necessary to disconnect the power cables from the
connector terminal block on the left hand side of the PCB.
The chassis is held in place by two screws. Undo the two screws and lift the chassis gently away from
the box towards you.
With the chassis removed, there is much more room inside the panel for making off and dressing cables.
When cabling work is complete, the chassis can be re-fitted and the power cables reconnected.
Important! Ensure the power cables are connected correctly.

8 Connecting to the circuit board
All connections for field wiring are to rows of terminals along the top and bottom of the circuit board.
Shielded fire alarm cable such as FP200 and metal cable glands must be used for all connections to the
panel.
The shield of the cable must be bonded securely to the enclosure earth via a metal cable gland.
The resistance of any core of any cable must not exceed 25 ohms. The shield of the cable must be
bonded securely to the enclosure via the metal gland.
Wiring should enter the enclosure at the top or back of the panel using the knockouts provided and be
formed tidily to the appropriate terminals.
Terminals are capable of accepting wires of up to 2.5mm
Wiring must not go across the front of the circuit board. If cable entries need to be in positions other than
at the knockouts provided, wiring must be fed behind and well away from the surface of the circuit board.
The space at the bottom of the enclosure is largely occupied by the standby batteries so this must be
borne in mind when considering cable entries.
8.1 Sounder circuit wiring
All sounders must be of the polarised type. If non-polarised sounders are used the control panel will
permanently show a fault condition. See table 2 for a list of compatible sounder types.
Sounder circuits are monitored for open and short circuit faults by placing a 10K 0.25W end of line
monitoring resistor across the last device on the circuit.
Sounder circuits must be wired as a single, radial circuit with no spurs or T junctions to enable the
monitoring circuit to work correctly.
