AB.12 INTRUSION ALARM SYSTEM

AB.12.1 General The primary purpose of an intrusion detection system (IDS) is to detect and signal the presence of an intruder or an intrusion attempt into a secured area. A secured area can be a selected room, an entire building, or group of buildings. The term 'supervised area/premises' herein after is used to describe the protected area or building. In principle, a basic intruder detection system will comprise a means to interface with the system user(s), e.g. a keypad with alpha-numeric display permitting authorised persons to interact with the system by setting and un-setting the IDS and viewing status indications. Control electronics connected to the user interface will perform the set and unset functions and will have provision to receive inputs from detection devices distributed throughout the supervised area/premises in strategically located positions. The action of signalling the intrusion event (or to use the correct terminology, ‘to notify’) is also made by the control electronics. The component parts of an IDS should be housed in discrete enclosures having a back-up a power supply. The system will have multiple detectors and a means of raising the alarm (sounders). This should be by means of audible siren, visible indicator (e.g. a strobe light) or a transceiver capable of sending an electronic signal or message to a monitoring centre or guarding force located either at the supervised premises or on another site remote from the supervised premises.

AB.12.2 Intrusion Alarm System General Requirements The system shall be able to interface with an electronic perimeter intrusion detector system comprising vibration sensitive piezoelectric microphonic cable directly attached to the fence and connected to dual zone electronic signal analyzers. The perimeter intrusion detector system shall be capable of detecting intruders cutting, climbing or jacking the fence. The system shall be capable of discriminating between intruder generated events and those generated by the environment and small animals.

AB.12.3 Intrusion (PIR) Detection & Burglar Alarm Systems Control Panel

The system shall be a modular type IDS system providing the option to expand the installation in future by means of expansion modules. Modules should be connected to a common bus at the most convenient location and their zone inputs shall be assigned to the desired zone and partition. Keys-witches, remote controls, and unused module inputs not to use zones. Once installed, all common bus modules (including motion detectors) should be able to be programmed remotely via a keypad.

SECTION IV: PRICED ACTIVITY SCHEDULE Procurement Reference Number: W/RFQ/AGRI – 01/2019-2020 REFER TO THE ATTACHED BILL OF QUANTITIES. The objectives of the Bill of Quantities (BoQ) are:

a) to provide sufficient information on the quantities of Works to be performed to enable bids to be prepared efficiently and accurately; and

b) when a Contract has been entered into, to provide a priced BoQ for use in the periodic valuation of Works executed.

The General Conditions of Contract, the Special Conditions of Contract (if any), the Specifications and the Drawings are to be read in conjunction with the BoQ. The BoQ comprises items covering the Contractor's profit and costs of general liabilities and of the construction of temporary and permanent works. The Bidder is at liberty to insert a rate of his own choosing for each item in the schedule and his attention is drawn to the fact that the Contractor has the right, under various circumstances, to payment for additional works carried out and that the Project Manager is obliged to base his assessment of the rates to be paid for such additional work on the rates inserted in the schedule by the Contractor. Unless otherwise stated, items are measured net in accordance with the drawings, and no allowance has been made for waste. The prices and rates to be inserted in the BoQ are to be the full inclusive prices to the Employer for the work described under the several items. Such prices shall cover all costs and expenses that may be required in and for the construction of the work described, and shall cover the cost of all general risks, liabilities, and obligations set forth or implied in the documents on which the Bid is based. The Bidder shall ensure that his rates are exclusive of Value Added Tax (VAT) as laid down in existing legislation. A price or rate is to be entered against each item in the BoQ, whether the quantities are stated or not. An item against which no price is entered will be considered to be covered by the other prices or rates in the BoQ. The Bidder must price each item in the Schedule in BLACK INK. The quantities of this BoQ shall be regarded as approximate and not necessarily the actual amount of work to be done nor shall these quantities be considered as limiting or extending the amount of work to be done or material to be supplied by the Contractor. The Contract Price for the completed contract shall be computed from the actual quantities of work done and valued at the unit rates and Bid prices against the respective items in the BoQ. The BoQ must not be used for the ordering of materials and the Contractor is advised to acquire his own information from the Specifications and Drawings and to consult with the Project Manager before materials are ordered.
