The range of NTR gas release panels are state-of-
the-art intelligent panels, which enable a wide
variety of gas release applications to be
implemented. The panel is provided with default
settings to suit most INERGEN
®
, FM200™ and
CO
2
applications and can be programmed to suit
most other gas releasing applications. For
compatibility with latest standards the panel
complies with all relevant parts of EN54 part 2
and 4. The NTR panel is designed to comply with
BS7273 and can be installed to fully comply with
BS5839 Pt 1 and BS6266.
System Operation (Default UK Operation)
Stage 1 - The panel stays in Stage1 Fire Alarm
until the fire or false alarm source is removed and
the panel is reset or Stage 2 ensues.
Stage 2 - The panel stays in Stage 2 for 30
seconds (adjustable) to provide a Pre-release
Warning during which time the HOLD or ABORT
sequences can be initiated.
Stage 3 - The panel remains in Stage 3 Gas
Release for the solenoid firing time or until the
release confirmation is received from the High
Pressure Switch.
Stage 4 - The panel remains in the Fire Alarm
condition and indicates the gas released
message until the system is silenced and reset.
Failure to receive a release confirmation will
initiate a fault.
The user interface is provided through a
combination of LEDs and a 2 x 40 character LCD
display. The LCD display provides a full customer
definable text display of the alarm or fault
condition whilst also displaying zones in alarm,
fault or isolate status. The display also indicates
the outputs that have been activated.
