Panel sounders
Panel sounders are attached to the panel in two ways:
Standard built-in sounder outputs, a quantity of 4 – paired on 2 addresses
Optional sounder outputs, quantity dependent upon the number of boards installed.
Sounders can be connected directly to panel outputs, or to remote panel outputs. All sounders
can be programmed to operate on a "common alarm", or to be individually configurable by
means of I/O-mapping. All sounder outputs have their own panel point address. The point
address of each panel output which is connected to a sounder must be specified as a "sounder
output", in order for it to behave correctly. Panel sounders are usually powered from the panel
power-supply, but can also be powered by an external power supply. This is dependent upon the
number of sounders, the required sound output (in decibels), and whether the sounders are
connected to the panel, or to a remotely located RCU-panel.
Z-loop isolators
Number of loops, and number of loop-isolators on each loop, must be specified. In addition the
location of each isolator must be shown either on the schematics, or on the layout drawings. Up
to 16 loop isolators (limited to 11 to comply with EN54 specification) can be installed on a loop.
The panel includes 2 built-in isolator relays, giving a total of 12 isolated sections of cable.
Common relays
The normal state for common fire and fault relays must be defined. The defaults are; fire relay
(normally de-energised) and fault relay (normally energised).
Printer
Specify whether a panel printer is to be fitted, and specify the type of events that must be printed.
Events are categorized into Fire Alarms, Fault Alarms, Panel Operations and Outputs Activated.
Alarm time display
Specify whether the time of each alarm must be displayed on-screen or not. This information is
always printed on the printout.
Silence delay
A delay can be programmed to the SILENCE ALARMS key in order to prevent the system sounders
being silenced (turned off) too soon in the event of a fire alarm. The time can be set between 0 (no
delay) and 600 seconds.
