LONG RANGE ALARM APPLICATION

Application of Long-range alarm system


Possible configurations of long-range alarm system

Firstly, there are many possible configurations for the panic alarm system. A few combinations include one transmitter to many receivers and vice versa. However, complex architectures, like many transmitters to many receivers is also possible. Pressing alarm button from a location can activate either a siren or a set of sirens. Please note, not to extend the wire between the panic button and transmitter more than 10 meters. Though the transmitter to wireless siren distance can be over 3-4 Kms in open line of sight.

Alarm system configurations:

  • A transmitter-receiver set, with a panic button
  • Remotely activated siren (remote range around 100 meters)
  • A panic button transmitter to many receiver sirens
  • Many different ways to trigger a transmitter
  • Many transmitters can trigger siren (display to showcase transmitter number)

Wireless transmitter-receiver design and applications

Introduction

Long range alarm solution is a complete set of products for open area security. Moreover, consumers are quite impressed after using the long range alarm from past many years. Besides, the long range alarm solution gives a feeling of security for sensitive areas.
The majority of customers are from border security forces, army, and factory security. Consumers use it for vast oil field security and even for open factories for perimeter security. Furthermore, it is possible to use the solution at any location that needs an alarm button at a place and sirens at remote locations.

Centralized alarm

Components of the long range alarm:

  • High power long range transmitter
  • Siren alarms of various loudness
  • Panic alarm push button
  • Handheld remotes to trigger the alarm

Problem statement

Security needs to alert control room and other posts, in an event of an emergency. The distance of the control room and other posts are three to four kilometers away. Many places the GSM network is not always available.

Solution

Variation in the configuration:

  • Security room has a long range alarm transmitter. Attached to it is a panic alarm button. On press of the panic button, the alarm sounds in the control room
  • An alternate solution is also provided to activate the alarm. A time when the security personnel is not present near the panic button. He can press a handheld remote control to trigger the alarm
  • A control room has a display on which the security room number is visible
  • The complete system works on the latest RF wireless technology. Neither any installation nor any future maintenance needed

Long range transmitter models

Wall mount transmitters

Push button panic alarm mechanism connects an alarm button to the transmitter unit. However, the siren unit can be at a distant location. In rather emergency, a person needs to press the alarm button. As a result, the transmitter sends alarm signals to the far location sirens. Therefore, this activates the siren. Whereas, releasing the button turns off the siren. However, the wire length between the panic button and transmitter should not exceed 10 meters. Moreover, the transmitter-receiver distance can be over 3-4 Kms in open line of sight.

Transmitter features:

  • Single channel and multi-channel transmitter
  • 6-8 Kms range of communication (in open line of sight)
  • 2-3 Kms in urban areas
  • Operating frequency 380-480MHz
  • Operating voltage 12VDC @ 500-800mA
  • With/without weatherproof housing (as per requirement)

Wireless sirens

108/118/130 db sirens

Firstly, the receiver unit comprises of the radio receiver unit and a high decibel siren. When the transmitter triggers and transmits alarm signals, it reaches the receiver. Following this, the unit decodes the conveyed message and turns on the alarm siren. However, the receiver siren alarm comes 3 variants. First, a siren with 108 decibels loud sound, whereas the other unit’s sound is as high as 118-decibel volume. Moreover, 130 decibel sound wireless sirens are also available. Due to the blinking synchronization signal user can check the range of the receiver. And finally, for improving the range of communication, the receiver should mount at height. The extended antenna cable helps in improving the range even further if elevated. The reaction time of the panic button press to siren active is less than a second.

Features:

  • 108, 118 and 130-decibel siren sound
  • Less than 1 second reaction time
  • Sync indicator to check if the machine is in range
  • Operating voltage 12VDC @ 500-800mA

Wireless receiver indicator

The receiver unit comprises of radio receiver unit with 7-segment display. When the transmitter triggers the corresponding number flashes. However, the receiver siren comes 5 variants. Display with flashing light or even a code red/code blue. Moreover, this sort of display receiver flashes the calling transmitter number. Further, this accompanies with beeping sound from the unit to alert.

Features:

  • 7-segment display, flashing light or revolving light
  • Less than rather 2 second reaction time
  • Sync indicator to check if the receiver is in range
  • Operating voltage 12VDC @ 500-800mA
