INFINITY 8 INSTALLATION MANUAL 1. INTRODUCTION THIS FIRE ALARM CONTROL PANEL IS CLASS 1 EQUIPMENT AND MUST BE EARTHED. This equipment must be installed and maintained by a qualified and technically experienced person. 1.1 HANDLING THE PCBS If the PCBs are to be removed to ease fitting the enclosure and cables, care must be taken to avoid damage by static. The best method is to wear an earth strap, but touching any earth point (e.g. building plumbing) will help to discharge any static.

INFINITY 8 INSTALLATION MANUAL 2. FIRST FIX All wiring must be installed to meet BS5839: Pt1: 2002 and BS 7671 (Wiring Regs) standards. Other National standards of fire alarm system installation should be adhered to where applicable. 2.1 RECOMMENDED CABLE TYPES AND THEIR LIMITATIONS Screened cables should be used throughout the installation to help shield the Panel from outside interference and ensure EMC compatibility.
INFINITY 8 INSTALLATION MANUAL page). Other makes of detector will have different connections, but in general they are wired +IN & +OUT to same terminal, -IN to stripe side of continuity diode, -OUT to non-stripe side of continuity diode. Some makes will connect the +ve to a 470R load resistor, or a polarisation diode, to enable the detector to work correctly.
INFINITY 8 INSTALLATION MANUAL The termination for the above inputs must be as indicated on the main PCB (See page 15). The Earthing of the cable screens should be as shown on page 9. Approved Document No. GLT-201-7-1 Issue: 1.
INFINITY 8 INSTALLATION MANUAL 3. MOUNTING THE FIRE ALARM PANEL It is recommended that the panel’s door be removed to avoid accidental damage. Also, the termination PCB could be removed and stored in a safe place, while fixing the back box to the wall. 3.1 PLANNING CABLE ENTRY Fig.2 below shows the location of the cable entries to facilitate planning of wiring (home runs) to be brought to the panel. The grommets can be easily removed by a push from inside the control panel box.

INFINITY 8 INSTALLATION MANUAL 5. FIELD DEVICE TERMINATION 5.1 TERMINATING THE DETECTION AND ALARM (SOUNDER) CIRCUITS All cables entering the enclosure should use cable glands. The Detector and Sounder circuits should be connected to the appropriate connector block on the Termination PCB as shown in Figure 6 below.
INFINITY 8 INSTALLATION MANUAL 6. SOUNDER ACTIVATION DELAY 6.1 DECIDING TO USE A DELAY A delay of up to ten minutes from the Fire Alarm Panel being triggered, to its Alarm sounder outputs being activated, can be programmed into the panel by the Engineer. This is a particularly useful feature for schools, nightclubs and other public places where the nuisance and panic caused by a false alarm must be avoided. It should be noted that the delay period will apply to ALL DETECTOR zones.
INFINITY 8 INSTALLATION MANUAL 7. ZONE DISABLEMENT 7.1 WHY USE ZONE DISABLEMENT To aid commissioning and assist routine maintenance checks, any of the zones or the sounder circuits can be disabled. When a zone (or sounder cct) is disabled, the panel will not respond to any fault or fire signals it receives from that zone. This might be used if the system requires routine maintenance, and the customer needs the system to continue running, but doesn’t want spurious false alarms.
INFINITY 8 INSTALLATION MANUAL 8. ZONE TEST 8.1 WHY USE ZONE TEST To aid commissioning and assist routine maintenance check, a non-latching ‘one man test’ facility is available. When a detector or manual call point is triggered on any zone in Test, the Alarm sounders operate for approximately five seconds on and seven seconds off.
INFINITY 8 INSTALLATION MANUAL 9. GENERAL FAULT FINDING 9.1 ZONE FAULTS To assist in fault finding, the infinity panel will display zone faults as follows. The general fault LED will flash if a fault is present. On the first flash, any zones showing O/C will flash. The second time the General fault LED flashes, any zones with a Short Circuit fault will flash in conjunction with the General S/C LED. The cycle then repeats, showing O/C & S/C faults on alternate flashes.
INFINITY 8 INSTALLATION MANUAL a. The batteries have reached their final voltage. If the panel is not charging them, they will need to be replaced. 4 Flashes - Battery internal resistance too high a. The batteries have a high internal resistance, and will need to be replaced. 5 Flashes - Charger fault a. Check that the charger disable link J2 has not been removed b. If (a) is OK, then the charger circuit on the PCB has been damaged, and the PCB will need to be repaired or replaced 9.
