If you are responsible for Fire safety or are a resident of a high-rise, multi-occupancy property you will be only too aware of the increased awareness of the need for enhanced fire detection and evacuation processes.
The former ‘stay put’ guidance is now regarded as unsafe and has been replaced by a ‘simultaneous evacuation’ strategy.
Many properties have deployed a waking watch service; this is a fire protection service and involves marshals patrolling to lookout for potential signs of a fire. They are also responsible for raising the alarm.
These services are costing property owners and residents thousands of pounds. A Waking Watch service can be replaced by a wireless Fire Detection System. This meets all the required standards and is quickly and easily installed. The total one-off cost of a Fire Detection System can be less than 10 weeks of a Waking Watch service.

Platform for new services (e.g. video verification)
Needs no investment in new alarm panels
IRIS 800 sets up TCP/IP connection to IRIS Polling Engine and sends its identification (account number)
IRIS Polling Engine issues a random ‘challenge’ to authenticate the caller
IRIS 800 encrypts the challenge using its preloaded security key and sends the result back to Polling Engine. Status of all local comms lines also reported to Polling Engine
Polling Engine checks result and matches what it gets when it encrypts the challenge with its local copy of the keyIf OK, Polling Engine downloads any new parameters (e.g. poll period) to the remote unit and reports any comms status changes to ARC. Overdue polls reported to ARC
Alarm Transmission Procedure
Alarm dialler goes off hook, receives local dial-tone from the IRIS 800 and dials IP address of IRIS Receiver
IRIS 800 makes TCP/IP connection to IRIS Receiver and is authenticated, as with Polling
IRIS 800 issues ‘Handshake’ tone to alarm dialler and collects alarm signal. Alarm protocol (FF, CID or SIA) is auto-detected
Alarm signal is encrypted and sent to IRIS Receiver where it is forwarded to the ARC
IRIS Receiver confirms receipt to IRIS 800 which sends ‘Kiss-off’ to the alarm dialler
Benefits of IRIS Approach
IRIS Polling Engine does not need to know IP address of IRIS 800 – An alarm system can operate through Fire Walls, NAT Servers, Public/Private Gateways and over GPRS
High level of security – authentication and encryption using MD5 and RC4 algorithms – Security key itself is not transmitted
Each transaction has a random element so will appear different to interceptors
Every IRIS 800 has its own security key of up to 256 bits
Alarm signals passed transparently from dialler to ARC
Any interruption of transmission causes dialler to retry
