IAS-2 Product Guide
3.1.1 BATTERY Terminal
The IAS-2 unit is designed to run from a 24 VDC supply. The supply should be connected to the two-way
BATTERY connector on the main circuit board ensuring that the wires are correctly orientated. The minimum
recommended wire size is 16 x 0.25 mm (18 AWG), or larger if the supply is further than 5 m (16.4 ft) from the
system.
A ferrite core is provided for EMC compliance. This should be fitted to the supply wiring as shown in Figure 3-
2.
The power requirements are dependant on the fan speed – please see table in Section 11: Specifications for
details.
3.1.2 LOOP IN / LOOP OUT Terminals
The LOOP IN and LOOP OUT terminals are connected to the detector terminals on the display board. This
provides a convenient means of connecting the loop/circuit wiring to the unit and allows the display and
detectors to be removed during servicing by simply disconnecting the ribbon cable.
The loop/circuit wiring can also be connected directly to the detectors if required.
The loop/circuit wiring can also be connected directly to the detector mounting base if required.
Note: A ferrite core is provided for EMC compliance. This should be fitted to the Loop Lines wiring as shown
in Figure 3-3
3.1.3 Fault Relays
In the event of a fault condition, the FAULT1 and/or FAULT2 relay will change state. The terminals provide for
Normally Open (NO) or Normally Closed (NC) operation and can be wired to terminating resistors to simulate
a zone fault on a conventional control panel or a loop interface module for an analog addressable panel.
Note: NO/NC refers to the un-powered state of the relays. Under normal operation (non-fault conditions), NO
is closed and NC is open.
Note: Please note that the faults for Channel 1 will actuate the FAULT1 relay and faults for Channel 2 will
actuate the FAULT2 relay.
