Periodic Scheduled Testing; Introduction - Honeywell Touchpoint Plus Technical Handbook

8.3 Periodic Scheduled Testing

Periodic Scheduled Testing should only be carried out by a Honeywell authorised technician or a qualified person
trained in accordance with this manual.
The following tests will show as a Fault on the events log.

8.3.1 Introduction

The Touchpoint Plus system has two test modes available, which together enable a full system test.
The test modes are:
•
Field Inputs Test this tests all input channel devices without affecting any outputs.
•
Cause and Effect Test this test forces the Touchpoint Plus input channels to known states to test that the
correct relay output channels are activated.
The Touchpoint Plus system is not operational while in Test Mode, and all field device inputs
Test output conditions will be simulated and relays will be activated during the Cause and Effect Test.
When a test mode is activated the System Failure relay indicates that the safety function of the system is not
operating. A Fault will be seen on the User Interface and a Fault event will be recorded in the Event log.
Once a test mode is active, the system will remain in test mode per the timeout setting. User shall operate the test
mode prior to timeout setting value. (Refer to Ch.7.4 for timeout setting) The only exception is in the case of a power
cycle, when TPPL will restart in normal mode.
All events generated while the system is in test mode will be logged in the event history, which can be viewed by
selecting [ Menu>Information>Event History

Routine Maintenance and Scheduled Testing
Ensure that alternative safety arrangements are maintained during test, and
ensure that Normal Operation is restored as soon as testing is completed.
Ensure that relay activated output systems (i.e. emergency deluge / sirens etc.)
are isolated before starting the test.
Ensure that the system is returned to normal operation once testing is completed.
WARNING
will be ignored.
