(C1635 – Monitored, C1634 – Non-
monitored). 
o  Type 3 – Sounder output module (C1635). 
o  Type 4 – Voyage data recorder output 
module (C1714). 
•  Pre defined zone group allocation for types 1, 2 
and 3  which  allocates  a group of 8 sequential 
zones to each board as follows. Zone groups 
are: 
Zones 1-8, 9-16, 17-24 and 25-32 
•  All terminals for field cabling are suitable for 
2.5mm conductors. 
•  Ribbon Cable connection to panel providing 2-
wire RS485 Serial Communications to all boards 
and DC power for C1634 (and other signals). 
•  DC Power supply input from panel or an external 
PSU depending upon application. 
•  A maximum  of  thirteen  output boards  can be 
connected to a single panel [4 off type 1, 4 off 
type 2, 4 off type 3, 1 off type 4]. 
Overviews for the C1630 interface and the C1714 
Voyage Data Recorder are provided below, further 
details of the Output Expansion Modules can be 
found in the Output Expansion Module Manual. 
4.2.9 C1630 Output Interface 
This PCB is fitted as standard to the T1216-C and 
T1232-C motherboard and is required when output 
expansion modules are used. It provides the 
communication path between panel and output 
modules. A 7-way DIL switch is used to set up the 
total quantity of each type of O/P board connected 
to the panel. 
4.2.10 C1714 – VDR Output Module 
The VDR output module provides outputs to signal 
critical Fire Alarm Panel conditions to the vessel’s 
Voyage Data Recorder unit. It is fitted as standard 
to the T1216-C  and T1232-C.  The VDR is not 
supported on the T1204. 
Five volt-free changeover contacts provide the 
following signals: 
•  Common Fire. 
•  Machinery space fire detected. [Any zone or 
number of zones can be configured to operate 
this output]. 
•  Common Fault – Fail-Safe. 
•  Mains Failed – Fail-Safe. 
•  Back-up Supply Failed – Fail Safe. 
A 2-wire serial data output (RS422) is also 
provided, which conforms to IEC 61162-1.  This 
provides zonal status information  as well as the 
above signals (see section 10. on page 24). 
4.3  T1200-C Repeater Description 
The repeaters use the same display (de-populated 
& different overlay)  and enclosures as for  the 
T1216-C  & T1232-C  fire alarm panels.  The 
motherboard is a de-populated C1626 board. The 
repeater and fire panel mechanical arrangements 
are similar. The C1631 Repeater interface board is 
fitted to the repeater motherboard and must also be 
fitted to the fire panel motherboard. Repeaters are 
powered directly from the 24Vdc output from the 
T1216-C & T1232-C  panels. An optional Muster 
Interface  board  (C1665)  is available  and  must be 
fitted to all repeater panels and the fire alarm panel 
if a muster fire condition is required to be initiated 
from repeater panels. 
Repeaters are not provided for the T1204.
