This manual is intended as a complete guide to the 4 zone conventional Surveyor ENVOY MINI 4 fire
alarm control panel. Installation and commissioning instructions are provided in the first part of the
manual with the following sections dealing with technical details and operation. A separate Log Book is
also provided.
System Design and Planning
It is assumed that the system, of which this control panel is a part, has been designed by a competent
fire alarm system designer in accordance with BS 5839 Part 1: 1988 (from 15th July 2003 this will be
BS5839 Part 1: 2002) and with regard to BS EN 54 parts 2 and 4 in the case of control equipment and
power supplies. Design drawings should be provided to clearly show the position of any field devices
and ancillary equipment.
Panel Types
FCPENV-MINI 4 – A four zone, non extendable control panel with an integral 1.0 Amp PSU and
space for 2 x 12V S.L.A batteries. Cabinet size: 277mm Wide x 200mm High x 97mm Deep
General
The control panel is a micro-processor controlled, conventional fire alarm control system, comprising of
one circuit board. The enclosure consists of back box and hinged, removable lid. Constructed of 1.2mm
(18swg) zintec mild steel and powder coated in textured light grey. The enclosure is designed to give
protection to IP30 level (for indoor use only)
The control panel is available as a 4 zone only and has no provision for repeater panels.
These panels are designed to comply with the requirements of BS EN 54 part 2 1998, but include
integral facilities to enable connection to older systems, which may not comply with current standards.
The control panels are compatible with a wide range of detection and alarm devices. Refer to technical
specification for details. The ENVOY MINI4 control panel has integral detector removal monitoring and
no special active end of line units are required.
ENVOY MINI4 control panels are simple to install and operate. Control functions are enabled by code
entry. The panel fascia is retained by a security cam lock . No internal access is required under normal
usage.

MENV-MINI4-02 Issue2 June 2006
SECTION 2 – INSTALLATION
General
•
The installation of fire detection and alarm systems should be carried out in accordance with
current IEE wiring regulations and in line with B.S.5839 British Standard codes of practice for fire
alarm installations. The installation should be carried out by suitably qualified and experienced
technicians.
•
Care should be taken with regards to avoiding the close proximity of high voltage cables or areas
likely to induce electrical interference. Earth links should be maintained on all system cables and
grounded in the control panel.
•
Any junction boxes used should be clearly labelled FIRE ALARM.
•
Any ancillary devices, e.g. door retaining magnets, must be powered from a separate power
source.
•
Any coils or solenoids used in the system must be suppressed, to avoid damage to the control
equipment.
ESD PRECAUTION
Electronic components are vulnerable to damage by Electrostatic Discharges (ESD). An ESD wrist
strap, suitably grounded, should be worn at all times when handling pcbs. These wrist straps are
designed to prevent the build up of static charges, not only within a persons body, but on many other
materials. ESD damage is not always evident immediately, faults can manifest themselves at anytime in
the future.
All pcbs should be stored in static shielded bags (silvered) for safe keeping, when not mounted in the
control panel. Do not use “black” or “pink” bags and never allow pcbs to come in contact with bubble
wrap or expanded polystyrene (packing chips).
Static shielded bags and disposable wrist straps are available from the manufacturer.
Warning, Control Panel Access Keys
The keys to the control panel must be kept, safely, by a responsible person. Hazardous voltages may
be present. Access to the inside of the panel is not normally required. Disconnect mains supply prior to
opening cabinet.

MENV-MINI4-02 Issue2 June 2006
Cable Types and Limitations
All System wiring should be installed to meet BS 5839: Pt 1: 1988
(from 15th July 2003 this will be BS5839: Pt 1: 2002) and BS 7671(Wiring
Regulations). Other national standards of installation should be used where applicable
To comply with EMC (Electro Magnetic Compatibility) regulations and to reduce the risk of electrical
interference in the system wiring, we recommend the use of screened cables throughout the
installation. Acceptable, commonly available, screened cables, which can be used on both the sounder
and detector circuits include FP200™, Firetuff™, Firecel™, MICC (Pyro™) or any other cable
complying with BS 6387 categories C, W, Z.
Mains Wiring
The mains supply to the fire alarm panel should be hard wired, using suitable three core cable (no less
than 0.75mm2 and no more than 2.5mm2) or a suitable three conductor system that meets the
appropriate national national wiring regulations. The panel should be fed from a double pole, isolating,
switched, fused, spur, fused at 3A. This should be secure from unauthorised operation and be marked
‘FIRE ALARM: DO NOT SWITCH OFF’. The mains supply must be exclusive to the fire panel.
As an alternative to a switched fused spur, a double pole isolating device may be used (see diagram)
providing it meets the appropriate national wiring regulations.
NOTE: Any isolating device used, must have a minimum 3mm contact gap.

MENV-MINI4-02 Issue2 June 2006
Planning the Cable Layout in the Panel
The detector and sounder circuit cabling is classed as extra low voltage and must be segregated away
from mains voltages. Careful planning is needed to ensure this, refer to Figure 1 (below) for guidance
and important information on how to remove the panel’s knockouts. Always ensure that if a knockout is
removed, the hole is filled with a good quality cable gland. Any unused knockouts must be securely
blanked off.
Figure 1 : Location of knockouts for cable entry and knockout removal details
Fixing the Cabinet
Remove outer cover by unlocking the door, drop down fully, remove Earth connection, slide lid to the
right, then pull gently towards you. Disconnect transformer and earth connections at top l/h corner of
PCB using small terminal driver. The terminals are marked ac (white wires) and Earth (green and
yellow wires). Remove circuit board from back box by unscrewing 3 in number M4 cross headed screws
from the circuit board supports. Place circuit board, lid and fixings in a safe position.
Secure cabinet to the wall using the four indented holes in the back box (see figure 2). Ensure that the
box is mounted in a convenient location where it may be easily operated and serviced and where it is
away from possible sources of vibration or shock, i.e., on partition wall next to a slamming door.
External cables should be glanded via pre-formed knockouts at the top and rear of the box as provided.
The enclosure should be cleaned of swarf etc., prior to refitting of printed circuit board.
Disconnect the battery leads from the circuit board by a pull out connector at the top l/h corner of the
PCB. Insert batteries and connect the battery leads to the battery terminals before replacing circuit
board. Ensuring the white link lead is also connected.

Mains Connections
The general requirements for mains wiring is described on page 5.
Do not connect the mains supply to the panel until you are fully conversant with the layout and features
of the equipment. A rating plate is fitted in the bottom left hand corner of the panel describing the nature
of the supply permitted.
The incoming mains supply should be brought into the panel in the bottom left hand corner, via the
knockout provided. A suitable cable gland must be used to secure the outer sheath of the cable used.
The earth must first be connected to the primary earth stud (peg) marked with a
crimp provided.

SECTION 4 – COMMISSIONING
General
The commissioning procedures should be completed one step at a time, as described below, to avoid
unnecessary problems. By following a logical sequence any faults that may occur can be quickly
identified and rectified before moving on to the next step.
Before connecting external circuits to the control panel it is recommended that the panel is powered up
and tested, and any faults cleared before proceeding.
Ensure that 4K7 resistors are fitted into zone and sounder circuit terminals before applying power.
To clear the battery fault indication when the mains is connected, a battery must be connected to the
battery terminals; it is not possible to inhibit the battery fault by the insertion of a resistor.
The system may be operated on the battery supply, i.e. if the mains supply is not available.
Powering the Panel
Remove the fuse from the mains input. Connect the supply wiring to the terminal block. Check that all
connections are sound and that 4K7 EOL resistors are fitted to zone and sounder circuits.
Refit the fuse and switch on the mains supply. The panel LEDs are illuminated momentarily, the ARW
LED remains lit and a battery fault is indicated. The internal buzzer sounds.
Connecting the Battery
The standby battery comprises two 12V, S.L.A. cells of a capacity suitable for the required standby
period and total alarm load.
Batteries may be located in the panel or in a separate cabinet depending on the battery size.
Battery leads are provided, including a battery link.
The SUPPLY HEALTHY LED should now be illuminated. The ARW LED should be illuminated and the
internal buzzer pulsing.
Enter Activate Controls code, (default code is 1234 ENTER) and press RESET.
All the LEDs are lit momentarily, the ARW LED should extinguish and the buzzer should be silent. The
panel is now operating correctly in the quiescent mode.
Any faults that are indicated at this stage should be investigated and cleared before proceeding. If
necessary refer to the fault location chart on page 13 for further information.
If unfamiliar with the Surveyor ENVOY Series equipment, it is advisable to explore the panel operation
and become conversant with the controls before proceeding. Faults can be simulated by open and
short circuiting zone and sounder circuits, fire alarms can be generated by shorting the zone terminals
with a 470R resistor. Refer to the Operation section if required.
Disposal of Batteries
Respect the environment. Batteries must be disposed of responsibly and in accordance with any local regulations.
12
MENV-MINI4-02 Issue2 June 2006
Zone Circuits
The default mode of operation assumes that the zone circuit is configured for open and short circuit fault
monitoring, and detector removal monitoring, i.e. detector bases are fitted with a suitable diode.
If these conditions do not apply, e.g. when connecting a circuit from an existing system, the operating
parameters for each affected zone must be changed. Refer to the Engineering Options section for
details.
It is recommended that each zone is connected in turn and its operation proved before moving on to the
next zone.
Check that all detectors are fitted into their bases and that a 4K7 Ohm resistor has been fitted to the last
device. Remove the 4K7 Ohm resistor from the selected zone terminals and connect the zone pair,
observing polarity.
If a zone fault is indicated, investigate and clear before proceeding to the next circuit. If necessary refer
to the fault location chart on page 13.
Continue to connect each zone circuit until all are connected and fault free.
It may be preferable to test the operation of zone devices before proceeding with the connection of
sounders.
Sounder Circuits
The MINI 4 has two common sounder circuits. .
Polarised and suppressed sounders should be connected in a parallel circuit with no spurs or tees.
Ensure that the load of the sounders is within the individual circuit limits, and that the total load does
not exceed the panel limits, taking into account any additional load imposed by auxiliary circuits,
repeaters, etc.
Remove the 4K7 Ohm resistor from the relevant sounder circuit terminals and connect the circuit pair,
observing polarity. Ensure that a 4K7 Ohm resistor is fitted in parallel with the last device on the circuit.
Clear any faults before proceeding – refer to the fault location chart on page 12 if necessary.
Sounders can be tested by operating the SOUND ALARMS push button.

MENV-MINI4-02 Issue2 June 2006
SECTION 5 – FAULT FINDING
General
A fault is indicated by the illumination of the SYSTEM FAULT LEDs and a buzzer tone. Specific faults
are identified by additional fascia indicators, e.g. zone fault. The buzzer tone varies depending on the
fault and may, or may not, be silenceable.
Fault Latch
If an intermittent fault exists, it is possible to make all fault indications latch, to help identify problems. To
activate fault latch, select option DIL switch 1 to ON.
Zone Fault Indications
Steady zone fault LED =
Zone in test or disabled
Pulsing zone fault LED =
Zone in fault condition
Identify the nature of the zone fault with the following method. When a zone fault is present:
Press and hold:
Button 1 to identify open circuit fault
Button 2 to identify short circuit fault
Button 3 to identify detector removed fault
If the zone fault indication remains when any of the buttons are pressed then that is the fault identified. If
the indication clears when the button is pressed then that fault is not present.
14
MENV-MINI4-02 Issue2 June 2006
Fault Finding Chart
The following chart identifies the indications that may be displayed, with the possible cause and the
recommended action. Fault location should be tackled logically by isolating fault paths until the source
is apparent, e.g. disconnecting zone and sounder circuits to prove if the fault is on the circuit or in the
panel, etc. Faults on external circuits can be traced by breaking down the circuit, e.g. placing the EOL
at the mid point of the circuit and determining which half is affected.

MENV-MINI4-02 Issue2 June 2006
Routine Maintenance and Testing
It is essential that the fire alarm installation is checked regularly by a responsible person for correct
operation in accordance with EN54 Part 2 or BS5839 Part 1. or applicable standard.
CLEANING
The exterior of the cabinet may be cleaned when required using a clean, moistened cloth. Do not use
solvents or abrasives as these will damage the panel.
ROUTINE TESTING
Routine checks should be carried out as detailed in this section of the manual. It is essential to keep the
log, in order to maintain a record of tests, checks, alarms and faults. A log book is provided with this
instruction manual. The log book should be kept with the panel and be available for inspection by an
authorised person.
DAILY
Check that the green, “SUPPLY HEALTHY“, indicator is lit. If the indicator is not lit, record the fact in the
log book and call for a qualified electrician to check the power supply.
WEEKLY
Carry out the daily check.
Operate one detector or call point on one zone and check that the panel responds to the alarm and
operates the warning devices. Record the results of the test and the zone detector/call point operated,

When fully satisfied that there is no fire, return to the control panel and press the RESET button,
see fig 3. Once the system has been reset the light on the detector should extinguish and only the
green SUPPLY HEALTHY lamp should be lit on the control panel.
If the system continues to false alarm, call an engineer.

engineer.
The internal fault buzzer can be silenced by pressing the ENTER button. DO NOT RESET THE
SYSTEM UNTIL AN ENGINEER HAS INVESTIGATED THE FAULT.
See relevant section in the installation and operating manual for details of disabling and
