2.1.3.3
INPUT OUTPUT RESPONDER (IOR)
The Input/Output Responder (IOR) provides up to 32 digital inputs and up to 32 digital (or
relay) outputs, depending on its setup and the termination boards attached to it. To the FIP,
the IOR appears to be up to 8 ADRs (or ARR). The IOR is ideal for when a large number of
switched inputs or outputs are required at the same location.
2.1.3.4
MULTI-PROTOCOL RESPONDER (MPR)
The Multi-Protocol Responder (MPR) allows up to 200 analogue addressable devices to be
connected on a loop of its own. These devices may be analogue addressable smoke
detectors, addressable thermal detectors, addressable device units (ADU) that provide
specific input and output facilities, or addressable monitor and control modules. The
addressable devices may be mapped to zones in the same way that ADR circuits are.
MPRs with V1.01 or earlier software are limited to devices using the EWD protocol, ie Nittan
analogue addressable smoke detectors, ADUx I/O devices and the Z54A addressable base.
The operation of these MPRs is similar to the AAR.
MPRs with V2.00 or later software are able to communicate with one of two device families,
i.e.
(a)
EWD Devices
,ie Nittan analogue addressable smoke detectors, ADUx I/O devices
and the Z54A addressable base; or
(b)
"130 Series" Devices
, ie smoke detectors, thermal detectors, monitor modules and
control modules.
EWD DEVICES
"130 SERIES" DEVICES
C7xA Smoke
C131A Smoke
P7xA Smoke
P131A Smoke
ADU002 Input
T131A (with Type A or B operation) Heat
ADU003A Output
ADM130 Input
ADU004A Output
ADM131 Input
ADU006 Conventional
ADM133 Input
Z54A Heat Base
ADC130 Output
The device family is programmable on a per MPR basis, and an F4000 system can support
"130 Series" MPRs on the same F4000 responder loop.
2.1.4 F4000 COMMUNICATION LOOP
The F4000 "COMMUNICATIONS LOOP" is a 4 core loop that runs from the FIP, through
each Responder, and back to the FIP again. The loop powers the responders, and allows
the FIP to receive the circuit status from the responders and control their outputs.
The 4 wires of the communications loop are:
(a)
Responder Power - 24V DC
(b)
0 Volt Common
(c)
Communications Path 1
(d)
Communications Path 2
The loop structure is such that it provides a very high degree of immunity against fault
conditions. A short circuit between any two wires or an open circuit in any wire is detected
and isolated so that the FIP is still able to power and communicate with all Responders.
