5.4.5 Sounder Fault Monitoring
•
Once commissioned any open or short circuits occurring on any of these inputs, either on-board or remote, are
automatically detected, recorded in the event log and displayed. For example:
! WARNING ! SOUNDER B SHORT CIRCUIT
5.5 Relays
•
Most of the programming and functions of the relay outputs are the same as for the programmable sounders. The
exceptions are:
1. There is no circuit monitoring on any relay outputs and as such any open or short circuits occurring on any
external wiring can not be detected and is therefore ignored.
2. Unlike the programmable sounders, the relay outputs can not be programmed to pulse.
5.5.1 Fault Relay
•
The EN54 specification requires that a fault relay be permanently energized and de-energizes under fault
conditions. Relay No.1 is pre-programmed to function in this manner.
5.6 PC (Remote Programming)
•
This configuration option allows a PC connected to the serial port to control the panel for uploading and
downloading panel text and configuration details. It is possible to prepare or alter installation information using an
IBM compatible PC and upload the data from a portable PC into the panel. This is particularly convenient when
large amounts of text, or complex ringing patterns are required. In this way, a backup copy of the site
configuration can be kept to allow rapid reprogramming if required. Refer to the PC programming manual (P/N
996-076) for details.
