Description
' : 1 s IMPROVEMENTS IN O~_R~LATING TO P~RSONN~L
fi~E~Y ARRANG~MENTS
.
This invention relates to personnel ~afety arrangements, and it relates e6pecially though not exclusiYely to such arrangements for a~sisting the evacuation of perl30nnel from bulldings or other enclosed areas, or areas with restr1cted 5 egre6s and access polnts, under emergency conditions. Typlcal emergency conditions include (without limitation) ~tructural damage due to fire or other cau~e~, terror~st activities or threat thereof, escape~ of toxic fumes, mob violence etc.
~ In many such circumstances it is considered desirable to t lO provide an arrangement which automatically guides evacuees toward exits. Such arrangements are described, for example, in Briti6h Patent No. 1,498,483 and United States Patent ~ No. 4,347,499. A difficulty with such arrange~ent6, however, is l~ that unless special step~ are taken to the contrary, it i6 ~-~ lS possible to direct personnel in the immediate vicinity of the ¦; emergency toward exits which are unusable or, wor6e still, towardthe cause of the emergency. -~
Thi6 invention aims to reduce the above-mentioned difficulty and thus, in acordance with the invention, there i6 20 provided an emergency evacuation arrangement for a structure or region having limited egress locations, the arrangement including a plurality of sensor mean6 each for sensing an emergency situation at a respective zone of said structure or region, and ..
for generating electrical fiignals indicative of at 25 leaRt the exi6tence of an emergency situation and the location of the zone associated with that sensor, processing means arranged to receive electrical signals from said sensors and to process said signals to generate alarm indication signal~ and escape route indication signals, and means responsive to the 30 indication signals generated by said processing means to supply alarm indication ~ignal6 only to any zone in which the existence of an emergency ~ituation is sensed thereby to generate in any such zone n warning of sald emergency situation without escape route indication, and to supply e~cape route indication signals 35 together with alara indication signals to other zones, thereby to -' ' ~
: 2 s generate in said other zones a warning oP said emergency situation and a route for safe eBress for personnel in ~aid other zoneA.
The arrangementa of the invention thus warns personnel ln the zone at which the emergency situation has been ~ensed that the emergency situation exist~ but does not attempt to direct such per~onnel with regard to egress from that zone. In other zones, per~onnel are both warned about the emer~ency situation and guided ~ -~
to 6afe egress locations.
In order that the invention may be clearly understood and ~ -readily carried into effect, and embodiment thereof will now be described, by way of example only, with reference to the accompanying drawings of which: -Flgure 1 shows a schematic layout of a structure from which - ;~
~ egress of personnel is to be controlled $n an emergency situation, -~
1 15 Figure 2 show~ a schematic electrical system for controlling! the egress of personnel from the structure of Figure 1~ and Figure 3 shows a route marker suitable for use with an arrangement in accordance with the invention.
Referring now to the drawing6, the structure shown in Figure 1 comprises a galleried layout although this i~, of course, in no way material to the invention. The structure 1 comprises a ~ peripheral gallery 2 which communicates with four main external ¦ doors, 3-6, and with various internal door6 7-10 which, in turn communicate with respective internal zones 11-14 ~-of the structure 1.
There are additional zones 15-18, and further internal doors 19-29 wh~ch permit communication between various of the zones but which do not directly communicate with the gallery 2. -The zone~ may be rooms, offices, laboratories or may indeed have any kind of function. Each of the zones 11-18 is provided with a respective sensor device 30-37 which, in each case, may be capable of sens~ng the existence of one or more alarm-worthy situations. Each sen60r, for example, may have the ability to detect smoke, flame, heat and vibration or any of these or other possible indicationa of the existence of an emergency s~tuation.
,~ ,, .

~ : 3 S
., , i The ~ensor devices generate electrical ~ignals indicative of the ~ ex~stence of an emergency situation (and possibly al~o of the type;~ of emergency if the devlces are capable of responding to a number of stimuli) and these signals are fed into a central processing unit 38.
The unit 38 receives and correlates all input 6ignals from the sensor devices 30-37 and also i~: preferably arranged to carry out regular check~ on the functionality of the devices. The unit 38 i~ also capable of ascertaining in which zone each detector device is located. This may, for example, be achieved by each device generating an identity code which is transmitted to the ~-unit 38 for correlation with a look-up table held within a ¦ non-volatile memory in the unit 38 or in any other convenient manner. ~n ~l 15 By the above means, the unit 38 is rendered aware of the ~
exi6tence of, and possible also the nature of, an alarm worthy ---situation and of the zone in which such a situation has occurred.
Each zone has an alarm indicator, shown as an acou~tic generator 39-46, although warnings other than, or in addition to, audible warnings can be given f desired, and escape route direction mark~ngs along approved routes therein. The escape routes are indicated as pathways by dashed lines in Figures 1 and by blocks 47-54 in Figure 2.
In response to the detection of an alarm-worthy situation, 25 the unit 38 iæ effective to energise the acoustic alarm indicators -~
39-46 in all ~ones and to energise the escape route direction markings 47-54 in all zones other than the zone or zones in which the alarm-worthy situation i8 sensed to exist.
For eaæe of explanation, it will now be considered that an alar~-worthy condition has been detected in zone 11 by the ~ensor device 30 located therein. An electrical signal indicative of the existence of the sensed alarm-worthy condition and of the ldentity of sensor device 30 (and thus of the zone 11) ls generated and conveyed to the unit 38. Unlt 38 respond6 to this signal by energisin8 the acoustic alarm indicators 39-46 in all zoneæ and ::
I : 4 s ~, ,, , , .
~ the e~cape route direction markings 48-54 in all zones except the ~-} zone 11. Extra e~cape route direction markings can be provided in the gallery 2 if desired. ~
The energ~OEation of all acoustic alarm indicators 39-46 and -, all e~cape route direction markings except for those indicated at 47 in zone 11 is illustrated in Figure 2 by 6chematic indications of sound wave6 and the inclusion of arrows in boxe6 48-54;
box 47 being empty to indicate that the relevant escape route direction marking6 are not energi6ed.
In Figure l, single-headed arrow6 are u6ed to indicate the direction of egress advised under the control of unit 38 ln certain zones. It will be ob6erved that, in some zone6, double-headed arrow6 are shown. Thi6 indicates that, for the relevant paths and for the particular alarm fiituation envisaged, - ;
it is feasible for personnel to leave in either direction. In such circumstances, the unit 38 may be conditioned 60 as not to ener~ise the route direction markings. Alternatively, and preferably, the unit i6 conditioned to review the overall egre situation and to select, for path6 and zone~ where more than one escape direction is fea6ible, that route which i8 most appropriate in the prevailing situation, bearing in mind that crowding at some egress polnts might be avoidable if per60nnel from certain zone6 are guided to other egre6s points and bearing in mind the desirability, where possible, of directing personnel away from the zone 11 at which the emergency has arisen.
The aforementioned de6irable conditioning of the unit 38 can, for example, be achieved by pre-programming suitable provisions for a number of pos6ible contingencies into the unit so that the appropriate reaction is automatically selected. In addition, as shown in figure 2, a manual input arrangement, via a keyboard 55 or any other convenient interface, can be provided whereby a controller can select certain modes of operation for the unit 38 and its associated components in dependence upon the actual situat~on as perceived by the controller, who may be based locally 35 to the 6tructure 1 or remotely therefrom but in visual ~
~'' ~'' s communication with the structure 1.
Figur~ 3 show6 a typical example of a vi~ual indicator or route marker unit 56 6uitable for use with an arrangement in accordance with the invention. These marker units such a~ 56 are ~-distributed along the various escape routes and, in particular, at decision points therein. They are capable of showing, on approach thereto from each of two directions, either a green arro~ or a red cross, depending whether or not a given route is to be followed in accordance with the evacuation programme selected by unit 38 The string of marker units such as 56 along any route can, lf de~ired, be repeatedly pulsed in sequence to encourage personnel to evacuate at a reasonable speed as well as in the desired direction. Pulsing may usefully occur between a "dim" condition and a '~right" condition, (rather than on-and-off) to ensure that at least some indication is always present of the preferred direction of evacuation.
Usefully, an audible warning can be associated with the units such as 56 and may be built into the same hou6ing or mounted closely thereto. If the audible warning is so distributed, it can 20 be advantageous to use the sound as a sonic arrow, by pul~ing -~
and/or frequency changing the emitted sound, in known manner. If this is done, even if smoke, dust or other material obscures the lighted direction markers such as 56, evacuating personnel can be guided by the sonic arrow toward the desired egress point.
The entire arrangement is, of course, preferably connected to the emergency power supply of the structure or other region in question and moreover the unit 38 is preferably conditioned so that, in the event of failure it maintains communication with the zones in accordance with the last instruction which it received.
