Technical information

This marine approved range is designed and
manufactured to a high standard and approved
by Lloyds Register to BS5839 part 4 and to
Marine ENV1 & ENV2.
Each panel in this series offers extensive
configuration options, in combination with
simplicity of panel installation, programming and
operation. This is supported by comprehensive
documentation relating to commissioning,
operation, maintenance and fault identification.
The precept marine panel is supplied in 2, 4,
8,16 or 32-zone formats. Panels are housed in
well-designed enclosures with partially glazed
doors. Steel parts are finished in durable epoxy
paint.
The motherboard and display electronics are
fixed to a detachable chassis, thus facilitating a
completely empty enclosure for first fix
installation. The motherboard is microprocessor-
based and includes all of the panel’s electronics.
Top-entry plastic grommets, bottom-rear entry
plastic grommets (for mains) and rear-entry
knockouts are designed to assist with cable
termination. All panels are designed for use with
marine-approved detectors.
All zones are monitored for both open and short
circuit fault conditions. To enable compliance with
BS5839 part 1, active end of line terminators are
provided to enable detector removal to be
monitored, whilst maintaining fire response from
the remaining detectors. Two alarm circuits are
provided as standard, monitored for both open
and short circuit faults.
Two changeover relay contacts operate on any
fire condition and latch until reset. One non-
latching changeover relay contact operates on
any fault condition. Zero volt open collector
outputs are provided for zonal fire conditions and
common fault. Three normally open inputs
provide for remote evacuate, silence alarms and
reset control.
