Magnetic Contacts will be placed on doors. When activated they produce a magnetic field between them. This magnetic field will be broken when a door is opened as one of the
contact will be fixed on the door frame and another, on the door itself.
Heat Sensors also detect the presence of fire, but in a different way than smoke sensors do. Heat sensors are useful in an area, where generated fire may not emit
smoke.
Passive Infrared Sensor or PIR is a motion sensing device. It operates in two phases. First it registers the different temperature zones with respect to the ambient
temperature, namely the body heat of an intruder. In the second phase it observes if the perceived temperature mass moves across the area covered by the PIR. PIR spreads
infrared pulses in passive and negative modes alternatively. Any movement within the area naturally cuts the positive and negative pulses which are invisible. This pulse
cutting results in a confirmed intrusion and a relay signal will be delivered to the intrusion alarm control panel for further action. All PIR units will have lines for
power, relay and tamper. Hence tampering the cables or opening the PIR case results in an alarm activation.
Smoke Detectors will sense the presence and level of smoke density, which is sufficient enough to catch fire. Each sensor covers an approximate 200 square feet unhindered
area (with no partitions and connected sections), at an average height of 8 feet from the ground.
Glass Break Detectors - Modern architecture and interior designing now-a-days demand glass encased structures and interiors. Protection of these glasses demand specific
sensors, which exclusively take care of protecting the same.
Photo Electric Beams will be used to detect intrusion along the compound or perimeter walls. A transmitter and receiver unit are mounted on the two extreme ends of the same
wall (which are in straight line and with no angular deviations in between). An invisible photo electric beam will pass between the two. Anyone trying to jump the wall will
cut the beam and hence an intrusion signal will be generated. Photo electric beams are available in single, dual and quad beams to suit the conditions which are dependent on
the level of risk and possibility of false signals.
