Summary of Terminations & Cautions
MCP LOOP
Used for the looping of the manual call point to a particular zone chosen for indication. This is achieved by
wiring from the zone, to the MCP, to the MCP loop then out to the field with the EOL across the last
detector. The MCP is the first device on the circuit and both fault and alarm conditions will be indicated.
(Refer to Section 4.5 for more details.)
DETECTION ZONES
Refer to list of compatible actuation devices for detectors which may be used (Table 4-1). Any other hard
contact device may be used on these detection zones. An end of line resistor (E.O.L) of 4K7 ohms is
required.
RELAY OUTPUTS
Relay outputs are voltage free change over contacts rated at 24VDC 1Amp (resistive). DO NOT attempt to
switch 240VAC with these relay contacts.
BELL OUTPUTS
This output is fused at 1 Amp and can drive up to 10 NIFS bells as specified. Output is also monitored and
if no bells are connected an EOL resistor (4K7 ohms) is required across the output terminals.
ACF OUTPUTS
This output is fused at 1 Amp. Output is also monitored and if no ancillary devices are connected, an EOL
resistor (4K7 ohms) is required across the output terminals.
WARNING SYSTEM
Connection to the warning systems such as “Occupant Warning System” or “electronic sounders”.
DOOR HOLDER OUTPUTS
When a door holder transformer is fitted to the panel, this output becomes functional. Output is rated at 3
Amps maximum and can power up to 30 NIFS style door holders continuously. (Nom. 80mA each).
Output is separately fused at 3A (FS-1). Jumper JP3 if fitted will disable this output, i.e. 24V DC output all
the time. The Door Holder Output can be isolated using the ACF Isolate function.
AUXILIARY POWER & MIMIC POWER (For IFS-2005 & IFS-2006 Boards only)
A total auxiliary power draw of 500mA is available from the auxiliary power and mimic power terminals.
This output is fused at 1 Amp (FS-3) and is battery backed.
MAF ISOL & TRANSPONDER 0V
A 0V signal is switched back from the transponder test switch and is used for indication purposes at the
FIP. This will indicate as MAF ISOLATED and initiate a common fault. It can also used for an external
device to indicate a fault.
NOTE:
Relay contacts shown at Terminals (NC, C, NO) are for the Relay in a De-energised
State.
