3.3.12  TPPR Modules 
TPPR is of modular construction so it can be easily expanded if required. The quantity and mix of I/O modules is optional 
and expandable. 
  Power Supply Unit (PSU) modules accept AC 120 – 240 V at 50/60 Hz single phase and are available in three power 
outputs: 24 VDC @ 120, 240 or 480 W. 
  The optional DC-UPS is an uninterruptible DC power supply that links to and charges the optional 2 x 12 V Sealed 
Lead Acid backup batteries. 
  The optional Redundancy Module (RDN) can control two DC 20A power inputs. If one input supply fails, the 
Redundancy Module will switch over to the other, maintaining the DC output. Alarm relays will open if one of the input 
supplies fails. 
  The Ring Coupling Module (RCM) enables fail-safe bi-directional (ring network) communication between modules and 
the controller. An RCM is required for each backplane in the system. 
 
Various types of I/O modules are available, each containing four channels. A single TPPR system can contain up to16 input 
modules offering 64 input channels and up to 32 output modules offering 128 output channels. 
 
Analogue Input Module 4–20 mA (AIM mA) 
4-channel Analogue Input Module for 2 or 3 wire 4-20mA sensor signals 
Analogue Input Module mV Bridge (AIM mV) 
4-channel Module for mV-Bridge signals; supports up to 4 catalytic bead 
flammable gas sensors 
Digital Input Module (DIM) 
4-channel Module for switched input devices such as manually operated 
push buttons. Can also be used for remote access to alarm acknowledge, 
reset and output inhibit inputs 
Relay Output Module (ROM) 
4-channel Module incorporating qty 4 SPCO (NO/NC) relays; suitable to 
activate field mounted external alarms, actuators, drenching or shutter 
systems, or to de-activate magnetic exit controls etc.

3.3.13  Sensor Catalogue 
The TPPR Controller is pre-loaded with an updatable sensor catalogue that lists all of Honeywell Analytics’ current gas 
sensors, each with a full default configuration setting that can be loaded when commissioning the Input modules. The full 
configuration can be viewed afterwards, and individual parameters changed if desired. 
The full procedure is explained in the Commissioning chapter.
