Revamping Armscor Head Office
On the fire detection and suppression side of the business Firetech Projects was recently awarded a contract to revamp the entire system at the Armscor head office and the adjacent Defence Headquarters (the security system in these buildings was carried out by Firetech some years ago). In the fire installation, some 15 Ziton ZP3 fire control alarm systems were linked on a peer to peer basis over optical fibre back to a PC in the control room operating a SCADA system with Firetech's developed software. Some 3000 devices (detectors, monitors, relays etc.) are monitored and backed up with five standalone audio racks feeding more than 2000 speakers located in over 30 zones.
The existing halon 1301 gas extinguishing system was replaced with a NAFS III gas system with more than 2000 kg of gas being available. The new extinguishing gas is environmentally friendly so the installation is now in full compliance with environmental directions to remove halon gases. A novel feature of the installation is that the on-site gas is not strictly zone allocated and in emergency the total amount can be used to control one devastating fire outbreak on one or several floors (and/or zones). The system will provide the threatened zone with alert and/or evacuation signals and extinguishers are automatically switched on. In the case of evacuation the system links in automatically to the access control system and all escape route doors are opened while captive fire doors (still easily opened for evacuation) are released to prevent spread of the fire. No water is used in this installation as it would, unlike the NAFS gas, cause enormous damage to computer and other electronic systems. This installation was commissioned at the end of March.
Maintaining Key Accounts
Firetech Intesol Projects was awarded the R7 million contract for the installation of the access control, fire detection and suppression system for the new domestic terminal at Johannesburg International. Firetech Projects Pty Ltd itself has an ongoing maintenance contract for the entire fire detection system at this airport.
Firetech Projects is also closely involved with the telecommunications industry in the area of fire detection and suppression, restricting the spread being essential for continued telecommunications operation in the event of a disaster. Installations have been completed in many of the fixed line operator's automatic exchanges and key buildings. The latter include the country's switching centre in Charles Street in Bloemfontein where the premises is protected with some 180-200 Bar Inergen gas cylinders, once again operating on a cross-over basis where maximum suppression can be focussed on the seat of the fire. A more recent installation was carried out at Telkom's new Centurion Extension which came on line at the end of June with 360 Inergen cylinders, one of the largest such installations on this continent.
The new SP warehouse for MTN in Midrand has an integrated system installed by Firetech Projects Pty Ltd that addresses intrusion detection, intercom, CCTV, Cardex access control, fire detection, evacuation and an electric fence. This was once again a fast-track installation and was tackled in three phases, namely the warehouse, the administration block and finally the canteen and main gate. The installation of the system in the critical warehouse area was completed in a record time of just three weeks and the total value of the contract was R2,8 million.
