HatchSecure Hatch Intrusion Detection System

Description

The HatchSecure system is a hatch detection system designed to protect access covers, particularly on secure sites. 
It's capable of detecting intrusion attempts through a variety of sensors that can identify tilt, impacts, sustained attacks, and the use of cutting torches. 
The system offers programmable outputs and software API for interfacing with other systems.
Managed by a central controller, it can monitor and control multiple sensor units and output cards.
The HDS uses MEMS accelerometers for detection of physical attacks such as impact and sustained attack from drills and cutting discs. These also provide tilt detection if mounted on the hatch lid.

The HDS has ambient light detection to detect the use of cutting torches to penetrate the hatch. General alarm inputs allow the use of contact switches to detect the hatch being opened and extra detection such as floats.

Equipment tested on a Steelway Brickhouse SA47 (SR4 rated) Upstand Single Hatch without moat drainage.
Equipment tested:
•    SA4000 Hatch Sensor (Standard Form Factor Enclosure), Firmware: vA1.44, Hardware v1.4
•    SB401 Output Card, Firmware: VA1.1, Hardware: V1.1
•    SB400 Controller, Firmware: VA1, Hardware: V1.1
•    Harper Chalice Secure Hatch Detector Config Application – Version 2.3
 

 

Requirements to maintain NPSA assurance:


-    An SR4 rated hatch must be used as a minimum, with a comparable lock.
-    SR4 rated hatches that do not have a self-drain moat require a float sensor. Self-draining SR4 rated hatches do not require a float sensor to be installed.
-    If the sensor is not mounted on the outer lid as a minimum a BS EN 50131 Grade 3, Class III magnetic switch or comparable device must be fitted to the hatch and utilised within the HatchSecure system as an input sensor.
-    Sensors must be mechanically fixed to the hatch. Chemical bonding must not be used.
-    The SA4000 sensor must use the small enclosure.
