Analogue Addressable Fire Alarms
Analogue Addressable Fire Alarm Systems
These systems differ from conventional systems in a number of ways, adding more flexibility, intelligence, speed of identification and scope of control. Addressable systems are usually installed in larger premises where detailed location information is required. This can then be provided to the Fire Service, minimising search times. Typical applications are schools, colleges, hotels, hospitals, industrial premises, nursing homes and complex offices
There are several key differences with analogue addressable fire systems :
Each detector, or call point has its own unique address and descriptive text which, is displayed on a control panel when the device activates.
Analogue sensors are wired on a continuous loop of cable with zones programmed via lap top computer not hard wiring. Sounders may either be conventionally wired or by using addressable sounders, wired upon the "loop" thereby making considerable savings in terms of cable and labour.
The system may contain one or more loops depending upon the size of the system and design requirements. The fire control panel 'communicates' with each detector individually and receives a status report e.g. Healthy, In Alarm or in Fault etc. As each detector has an individual 'address' the fire alarm control panel is able to display/indicate the precise location of the device in question, which obviously helps speed the location of an incident and for this reason 'zoning' of the system is not strictly necessary, but is often done for convenience.
Analogue smoke detectors can be programmed to warn of a nearing false alarm condition by triggering a local alert at the control panel known as a Pre-Alarm.
The programming of an analogue addressable system can be very complex allowing complex cause & effect to be programmed to assist with phased evacuation. Depending upon the requirements, limitless fire plans may be configured.
AFP 1 or 2 Zone Fully Analogue Addressable Fire Alarm Panel
Fully compliant with EN54 parts 2 & 4, this panel offers high performance at a competitive price.
Attractively designed, easy to use and simple to install, the AFP's improved specification now includes delay timers, phased evacuation facilities, adjustable contamination levels, the programming of non-fire events and additional auxiliary inputs and outputs.
These new features, combined with the panel's comprehensive range of existing features and straightforward programming via the AFP's intuitive upload/download programming software, make it the obvious choice for all one or two loop analogue addressable fire alarm applications.
Panels are supplied with an integral loop driver already fitted and are expandable to two loops via the AFP702 plug-on loop driver. For basic single loop applications that do not require repeater panels, a low-cost non expandable version of the AFP is also available.
- Compatible with Apollo XP95, System Sensor or Nittan protocols.
- 16 zonal alarm leds, expandable to 32 via the AFP703 extension LED kit
- Powerful short circuit protected loop drivers, capable of supporting up to 32 loop powered sounders per loop.
- Four separate independently programmable conventional sounder circuits.
- Alert, Reset, Silence and Class Change inputs.
- Fire, Fault, Remote, Pre-Alarm, Reset and 24V outputs.
- Comprehensive auto-learn facility allowing the panel to self-configure to devices connected to the loop(s).
- Integral 24V 3A EN54 switch mode PSU rated @185-260 Va.c, 50/60 Hz (1.5A PSU on AFPE).
- Programmable sounder / remote output delay facilities (per zone).
- Adjustable contamination levels.
- Earth fault monitoring.
- Phased evacuation facility.
- Push button access code entry to Access Levels 2 and 3.
- Sophisticated test and maintenance facilities.
- Intuitive easy-to-use Windows 95/98/2000 based upload/download PC programme.
- Space available for 7Ahr VRLA back-up batteries.
- Easy to read, 80 character back-lit display.
- 40 characters of custom text per device.
- 999 event monitoring.
- Optional AFP Network Driver Card allows the connection of up to 15 AFP repeater panels (this feature is not available on AFPE economy panels).
XFP 1 or 2 Zone Networkable Fully Analogue Addressable Fire Alarm Panel
Fully compliant with EN54 parts 2 & 4, the new range of networkable analogue addressable fire panels offer high performance at a very competitive price.
Available in two different versions (a cost-effective single loop 16 zone panel in a plastic enclosure and a robust 1 or 2 loop 32 zone metal panel), they offer an array of user and installer-friendly features, including:-
- Full compatibility with Hochiki's ESP and Apollo's XP95, Discovery and Xplorer protocols
- The ability to interconnect up to eight XFP main panels (any variant) plus an additional four XFP repeaters per main onto two wire RS485 networks
- Two independently programmable conventional sounder circuits
- Two programmable inputs
- A fault output relay and three programmable relay outputs with voltage free changeover contacts
- A day/night (building occupied/unoccupied) function
- An investigation delay period function (programmable for length of time, which zone(s) it applies to and whether or not it operates in day/night mode)
- Individual sensitivity settings for each device
- A phased evacuation facility
- An alarm counter that records the number of times the panel has been in an alarm state (to meet clause 7.13 of EN54-2)
- Powerful short circuit protected loop drivers, capable of supporting up to 40 loop powered 10mA sounders per loop
- An integral EN54 switch mode PSU rated @ 185-260V a.c. 50/60Hz (1.4A on 16 zone panel, 3A on 32 zone panel)
- Adjustable contamination levels
- Earth fault monitoring
- Push button access code or keyswitch entry to Access Levels 2 and 3 (depending on model purchased)
- An easy to read, 80 character back-lit display
- 40 characters of custom text per device
- 999 event monitoring
- Comprehensive test, maintenance & commissioning functions (including auto-learn loops, monitor a point, test outputs, one man walk test and loop continuity test)
