In response to your letter M&U-13-0024 dated October 10, 2013, we have the following comments;

1.	The Perimeter security system is designed according to HCIS SEC-02, clause 4.3 for Category 1 fencing system. Maintaining the functionality of Category 1 layers as separate entities "sharing a common border" or "contiguous" is crucial to design of the security system in this category with a layered approach and as described in the very first paragraph of the afore-mentioned clause and also in clause no 4.2.2 of SEC-02.

2.	Keeping in view the available space and existing facilities/utilities, maximum caution has been exercised to maintain the integrity of the layers as per requirements of HCIS. Any conflicts or deviations as mentioned in SEC-02, Para 1.3 shall be resolved by HCIS. SAPMT is of the view that KAUST preferences can be incorporated if a waiver is acquired from HCIS by KAUST.

3.	The current arrangement provides coverage over the ditch by one (1) system (Fix Camera) where an ALERT will be generated upon intrusion. An ALARM will be generated when intrusion continues after the ditch. The current arrangement of layers provides two levels of detection within defined security zone where both systems can generate an ALARM that will constitute an ALERT as per scope system configuration requirements. 

4.	Security Lighting System intensity is designed to provide the required lux as per SSD-13 within the defined security zone where clarity of intrusion image over the entire ditch is not guaranteed.
