ALARM HISTORY
  • ALARM AS A DETERRANT
  • A physical deterrent by the noise and attention
  • A psychological deterrent if a perpetrator knows
    or beliefs a building has an alarm system

WHY PEOPLE NEED AN ALARM SYSTEM

ALARM HISTORY
  • McCULLOUGH LOOP
  • McCullough Loop basically a single telephone line
    that is linked from site to site with a
    transmitter at each site.
  • When the alarm is tripped at that site, the
    transmitter signals a series of signals (similar
    to a telegraph key).

ALARM SYSTEM
Basic Alarm Circuitry
  • In a normally open loop there is not a complete
    loop from one side of the power source to the
    other

ALARM SYSTEM
Basic Circuitry Contd
  • In order for the loop to become a closed loop,
    the switch (or sensor) needs to be activated and
    moved to the closed position. When this switch
    is closed, we have a complete or closed loop
  • TCLEOSE Course 2101 Crime Prevention Part I
    Curriculum is the intellectual property of ICJS
    (2009)

46
ALARM SYSTEM
Basic Circuitry Contd
  • When the loop is closed, electronic pulse flows
    from one side of the control unit through the
    loop to the other side. With signal now flowing
    through the loop, the relay is energized and the
    alarm activates

ALARM SYSTEM
Basic Circuitry Contd
  • The biggest problem with this type of loop is any
    part of the loop may be cut without detection.
    For this reason, a normally open loop is referred
    to as unsupervised and is not commonly used by
    itself in alarm systems.
  • TCLEOSE Course 2101 Crime Prevention Part I
    Curriculum is the intellectual property of ICJS
    (2009)

49
ALARM SYSTEM
Basic Circuitry Contd
  • This configuration allows pulses to flow in the
    loop and keeps the relay energized. In this
    loop, as long as the relay is energized, there is
    no alarm. However, when the relay is
    de-energized, by activating the switch, the alarm
    alerts

    Curriculum is the intellectual property of ICJS
    (2009)

50
ALARM SYSTEM
Basic Circuitry Contd
  • If additional switches sensors are added to the
    normally closed protected loop, they must be
    inserted in such a way that opening any one of
    them causes an open circuit. To provide this
    feature the switches are hooked in series to one
    another (i.e., one right after another).

    Curriculum is the intellectual property of ICJS
    (2009)

51
ALARM SYSTEM
Basic Circuitry Contd
  • A normally closed loop is referred to as a
    supervised circuit since cutting any of the wires
    in the protective circuit activates an alarm
    condition.

53
ALARM SYSTEM
Basic Circuitry Contd
  • A basic weakness in a normally closed system is
    the switches may be "jumped out" or shorted
    across without initiating an alarm when that
    particular switch is activated. This
    characteristic of the closed loop is used when
    installing a device known as a shunt lock or
    shunt switch.

55
ALARM SYSTEM
Basic Circuitry Contd
  • The shunt switch is used to bypass a selected
    detector or zone, for instance, on the front
    door, so the premise is entered by authorized
    persons without sounding an alarm. By turning
    the shunt lock to the unlocked position a jumper
    or shunt is created around the selected
    detector(s).

  • Supervised Loop can be combination of open and
    closed loops monitored by computer that is
    constantly checking each individual sensor every
    few seconds. Cutting or splicing wires will not
    disarm the supervised loop

  • Remember that a Shunt Switch is used to bypass
    selected zone or detector for closed alarm
    system to allow entry into a zone without
    setting off the alarm.
