19. Panel Specification Summary
19.1. Recommended Cables
All field wiring should be installed using a shielded twin core cable (ideally with a blue outer sheath to allow easy
identification). The minimum cross sectional area should be 1mm although in the case of the detection loops this
depends upon the length of the cable and the number and type of devices fitted. Loop length calculators for
various cable types are available. Drain wires of any field wiring should be maintained throughout the length of
the cable and terminated at the panel via brass cable glands. Refer to
Section 4.1
for loop earth termination
requirements.
19.2. Sounder Load
Panel Sounder - Two 24 volt sounder circuits, each fused with a 1 Amp self-resetting electronic fuse. Each
sounder circuit is monitored using reverse polarity and a 10 k
Ω
ohm end of line resistor.
19.3. Current Consumption
1 loop panel current consumption
130 mA (power fault)
300 mA in alarm (no alarm load)
2 loop panel current consumption
195 mA (power fault)
370 mA in alarm (no alarm load)
I/O board current consumption
20 mA (quiescent), up to 1A in full alarm
8 way relay card current consumption
10 mA (quiescent), 250 mA in full alarm
6 way sounder card current consumption
30 mA (quiescent), 260 mA in full alarm + sounder load
4 way zone board current consumption
70 mA (quiescent), 250 mA in full alarm
19.4. Power Supply

19.5. Field Devices
Vimpex
127 devices per loop
Per 1 loop panel
127 ID Addressable modules
Per 2 loop panel
254 ID Addressable modules
Sub-address total
800 addresses and sub-address limit per panel.
19.6. Water Leak / Alarm / Fault Relay Ratings (see also Section 12)
All panel relay contacts are rated at 30 VDC and 1 Amp maximum.
Under no circumstances should voltages or currents outside of these limits be connected.
19.7. Zones
All panels have 16 Zonal LED indicators fitted. Care should be taken to ensure that no more than 32 devices will
affected by a single short or break in any detection circuit.
19.8. Remote Control Inputs (see also Section 16)
Unmonitored digital inputs, activated when connected to the Remote Control 0V terminal with an in line
resistance of less than 50 Ohms.
Note: Remote control inputs must be restricted by the Access Level requirements. Therefore it should not be
possible to remotely reset, silence or operate the alarm devices without some means of gaining access to this
function.
19.9. Auxiliary 24 Volt Monitored Output (see also Section 15.1)
Permanent 24 volt output protected by a 500 mA self-resetting electronic fuse, monitored for fuse failure.
