SECTION 1 – INTRODUCTION About This Manual 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.
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.
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.
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.
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.

SECTION 3 – ENGINEERING OPTIONS General The panel has various options which are programed by the selection of DIL switches. This section explains which switch relates to which option. DIL SWITCHES ON MASTER PCB, PCMINI4 Switch Function when ‘off’ Function when ‘on’ 1 Faults non latching Faults latch.
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.
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.
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.
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.
SECTION 6 – TECHNICAL DATA • • • • Mains input voltage ; 230Vac, 50-60 Hz (Harmonised) +10% to -15% compliant with BSEN54 Pt4 : 1997 for fire alarm power supplies. Nominal system voltage 24V dc.

SECTION 7 – OPERATOR INSTRUCTIONS Controls and Indications SEE TABLE 1 Enter code to activate keypad controls.
Controls and Indications Continued TABLE 1 A SUPPLY HEALTHY Indicates permanently when panel is correctly powered. B TEST MODE Pulses when the control panel is in engineer’s test mode. The individual circuit fault lamp will be on (steady) whilst the circuit is in test mode. It is not possible to test a disabled zone. See page 20 “Test Mode” for more details. C DISABLED Indicates when a zone or sounder circuit has been disabled using the disable button on the keypad.
Controls and Indications Continued TABLE 2 P TEST MODE “Test mode” button. Puts zones into test mode. See relevant section, page 20. Q DISABLE “Disable” button. To disable or isolate zones or sounder circuits. See relevant section, page 21. R TEST LEDs Pressing this button will cause all LEDs to illuminate briefly. S ENTER “Enter” button. Used to acknowledge selection of zone or sounder circuits for disablement.
Test Mode ZONE TEST To put zone(s) into test mode, enter code to activate controls and press the TEST MODE button on the keypad. Now use buttons 1 – 4 to select which zone(s) to put into test mode and press ENTER when all selections have been made. The test mode entry will “time out” within 5 seconds if the ENTER button is not pressed. It is possible to have any or all zones in test mode at the same time. The Test Mode LED will be on.
Disable Zones or Sounders DISABLE ZONES To disable / isolate zones , enter code to activate controls and press the DISABLE button on the keypad Now use buttons 1 – 4 to select which zone(s) to disable and then press ENTER when all selections have been made. The disable mode will “time out” within 5 seconds if the ENTER button is not pressed. It is possible to select any, or all zones, to be isolated at the same time. The disabled LED will be illuminated.
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.
USER INSTRUCTIONS Alarm Condition If all sounders or bells are ringing, the system is in an alarm condition. YOU MUST EVACUATE THE BUILDING OR FOLLOW YOUR NORMAL FIRE DRILL PROCEDURES. A responsible person should then:1 2 3 4 Check the control panel to see which area or zone has caused the system to go into alarm. The zone in alarm will be indicated by a red, flashing, light on the front of the control panel, see fig 1. Go to the area which has caused the alarm to check if a fire exists.
