contacts on doors and windows is the usual way to sensor these openings.
Most often they are concealed and home run to the alarm control
panel. Alarm screens which cover the entire window (allowing light
and air) maybe used instead of window frame opening contacts. Alarm
screens protect the entire window opening and detect attempted intrusion
before a burglar gains entry thru a window.
Motion Sensors: These products are designed to detect
motion within a protected area. They are passive infrareds, photoelectric
beam sets, ultrasonics, and microwave units. The best motion sensor
to use to suppress false alarms, is to utilize a dual technology
sensor. Passive infrared and microwave units are an example of a
combined technology that can surpress false alarms from environmental
conditions, yet detect an intruder. In homes that have pets, photoelectric
beam sets are used to prevent accidental activations of the alarm
while it is armed.
A manual alarm can be instantly activated by two means:
- From any
keypad by pushing a single or combination of numbers.
- From a wireless
transmitter button, used with a receiver connected to the control
panel. This feature is always available and has no bearing on
the status of whether the burglar alarm is armed or not. Panic
alarms usually activate the bell/siren to alert others and the
central station that there is an immediate personnel hazard occurring.
This gets a high response from our central station over any burglar
All of our systems offer a feature to have the means to send a silent
ambush signal to our central station. In the event that an operator
is under duress or ambush condition to disarm the system, or has
an emergency, a silent signal will be sent to our central station,
which also has a high priority of response.
Supervised: Usually used on
business/commercial security systems to remind employees to arm
the system by a certain pre-designated time. It can also determine
if employees disarm the system outside of pre-designated times.
Individual codes can further be assigned so that each arming and
disarming signal is logged to the individual employee or user.
Usually used for home security systems. It does not require arming
or disarming times, and one code can be shared for all family members
or individual codes could be assigned as well.
