Approved Document Ref: UI-ESA-01 Issue 1.0
PRODUCT OVERVIEW
Quality, reliability, ease of use and feature rich are attributes that are consistent across the
entire range of Haes fire alarm control panels. The ESPRiT Addressable panels encompass
all these attributes, to provide the fire alarm engineer’s panel of choice.
For the fire alarm engineer, the panel has been designed to be easy to install and to
minimise labour costs, by providing ample room for tasks such as wiring and changing
batteries. Activation is via key switch or access code, which means you should always be
able to work on the panel and the one man walk tests will help reduce the cost of
maintaining the fire alarm system.
The ESPRiT-Argus Addressable fire control panel is designed to be intuitive and flexible for
the fire alarm engineer to programme and incorporates a large 240 x 64-pixel graphical
display, with an easy-to-navigate menu system, which uses simple discernible icons in each
section.
Simplicity is one of the most important aspects when considering the end user of a fire alarm
panel. The easy to read control panel, with its graphical LCD display and five marked control
buttons, and the 3-step silence functionality gives non-technical people the confidence to
correctly manage their fire alarm system.
All inputs and outputs are fully programmable and there are options to have delays to the
outputs. The programming features also include 3 different modes to help reduce false
alarms. Local fire authorities are demanding this type of functionality to reduce unwanted
callouts from alarm receiving centres.
As an addressable panel, signals from detectors, manual call points or any other devices are
individually identified at the control panel’s LCD graphical display. In addition, the control
panel LED indicators will provide a simple ‘at a glance’ overview of which zone or zones
have gone into the alarm condition, showing the extent of fire or smoke spread.
The panel supports connections for up to sixteen Remote Status Units (RSUs), remote
control call points and repeaters, via an RS-485 Peripheral BUS (PBUS) circuit. The PBUS
circuit is not intended for networking.
ESPRiT Addressable panels are approved to European standards EN54-2 & 4, Fire
Detection and Alarm Systems –Control & Indicating Equipment.
This product has been designed and manufactured in the United Kingdom.
General Description of the Equipment
The control panel cabinet comprises of a sheet steel enclosure, suitable for wall mounting,
with a hinged lockable front access door. Cable entry is via 20mm ‘knockouts’ at the top and
rear of the cabinet.
Different key types are used for the door lock and the ‘activate controls’ key-switch.
This control panel is available in either 1 to 2 loops or 1 to 4 loops, in two different enclosure
sizes. Each loop can have up to 240 devices connected (480 or 960 devices in total).
This product has been designed to support Argus protocol.
The panels are supplied with one of two different internal power supply modules (depending
on panel size); 35W, 1.2Amps or 100W, 3.4Amps, each rated at 230VAC, 50/60Hz. These
modules comply with the requirements of EN54-4: 1988 and provide temperature
compensated battery management charging.

Approved Document Ref: UI-ESA-01 Issue 1.0
DESIGN CONSIDERATIONS
System Design and Planning
Note: This guide is intended as an aid to designers and installers of fire detection systems. It
is NOT to be used as a substitute to BS5839 which should be read in full.
What is a detection zone?
In order to direct those responding to a fire alarm signal, particularly the fire service, to the
area of a fire, all buildings, other than very small buildings, need to be divided into detection
zones. Detection zones need to be small enough for a fire to be located quickly.
If the total floor area of the building is greater than 300m2, each zone should be restricted to
a single storey
If the total floor area of the building is less than 300m2a zone may cover more than a single
storey
For voids above or below the floor area of a room, these may be included within the same
zone of the room, provided that the void and the room constitute a single fire compartment.
Any enclosed stairwell, lift well or other enclosed flue-like structure should be considered as
a separate detection zone.
The floor area of a single zone should not exceed 2000m2.
Zone indication should be given at the fire alarm control panel.
Detectors
The sensing element of a smoke detection device should not be less than 25mm and not
more than 600mm below ceiling
The sensing element of a heat detector should not be less than 25mm and not more than
150mm below ceiling
When mounted on a flat ceiling, smoke detection devices have an individual coverage of
7.5m radius. However, these radii must overlap to ensure there are no ‘blindspots’.
Therefore, individual coverage can be represented by a square measuring 10.6m x 10.6m
giving an actual coverage of 112m2 per device
When mounted on a flat ceiling, heat detection devices have an individual coverage of 5.3m
radius. However, these radii must overlap to ensure there are no ‘blindspots’. Therefore,
individual coverage can be represented by a square measuring 7.5m x 7.5m giving an actual
coverage of 56.3m2per device.
Call Points
A person should not have to travel more than 45m along an escape route to reach a Manual
Call Point (25m if disabled person to operate, or rapid development of the fire is likely).
Manual Call Points should be sited at all stair wells and exits from the building.
The frangible element of the manual call point should be positioned 1.4m (+/- 200mm) from
the floor level. (Unless a wheelchair user is likely to be the first person to raise the alarm).
Sounders
Sounder device cabling should be arranged so that in the event of a fault, at least one
sounder will remain operational during a fire condition.
The minimum sound level should be 65dB(A) or 5dB(A) above a background noise which is
louder than 60dB(A) (if lasting more than 30 seconds) and at a frequency of between 500Hz

ESPRIT-Argus User Manual DESIGN CONSIDERATIONS
17
Approved Document Ref: UI-ESA-01 Issue 1.0
and 1000Hz. The maximum sound level should not be greater than 120dB(A) at any
normally accessible point. This may be reduced to 60dB(A) in stairways, enclosures up to
60m2and specific points of limited extent.
For areas where people are sleeping, sounder devices should produce a minimum 75dB(A)
at the bed-head with all doors shut. In buildings providing sleeping accommodation for a
significant number of people, all bedrooms should have both audible and visual alarms.
Beacons
Visual alarms such as beacons, should always be mounted at a minimum height of 2.1m
from floor level.
General
Fire Alarm Control Panels should be installed at a location appropriate for staff and fire
fighters
All mains supply isolators must be double pole and suitably marked
All joints to be fire resisting, junction boxes to be labelled ‘FIRE ALARM’.
All cables to be fire resisting with a minimum cross-sectional area of 1mm2.
Cable using trunking as a means of containment must be clipped using fire resistant
supports WITHIN THE TRUNKING.
Zone charts should be fitted in all appropriate locations (adjacent to control equipment and
repeaters).
Cable Types and Limitations
To comply with EMC (Electro Magnetic Compatibility) regulations and to reduce the risk of
electrical interference in the system wiring, we recommend the use of screened cables
throughout the installation.
Acceptable, commonly available, screened cables, which can be used on both the sounder
and detector circuits include, NoBurn™ FP200™, Firetuff™, Firecel™, MICC (Pyro™) or any
other cable complying with BS 6387 categories C, W, Z.. Refer to BS 5839 pt1 clause 26 for
detailed information on cables wiring and interconnections.
Cabling
Suitable cables should be brought into the cabinet using the knockouts provided via a
suitable cable gland recommended for use with that cable. The screen or drain wire of
circuits should be bonded to earth at one location only and should be continuous throughout
the circuit. Drain wires should be terminated in the cabinet using the earthing terminal
provided.
Cable Lengths
The maximum recommended cable length for a zone or sounder circuit is 1Km. This,
however, is highly dependent on the number and type of devices connected.
If in doubt, cable load and resistance calculations should be undertaken to ensure devices
are working within specified limits.
Mains Provision
The mains supply to the fire alarm panel should be hard wired, using suitable three core
cable (no less than 1.0 mm² and no more than 2.5mm²) or a suitable three conductor system
that meets the appropriate national wiring regulations. The panel should be fed from an
isolating switched fused spur, supplied directly from the Main Distribution Board, fused at 3A.

This should be secure from unauthorised operation and be marked ‘FIRE ALARM’.
The mains supply must be exclusive to the fire panel.
As an alternative to a switched fused spur, an appropriately fused double pole isolating
device may be used providing it meets the appropriate national wiring regulations.
Note: All system wiring should be installed to meet BS5839 Pt 1: 2002 and BS7671 (Wiring
Regulations). Other national standards of installation should be used where applicable.
