Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: This wireless door/window transmitter, made by Visonic, is
designed for use with advanced, high-security alarm systems, such as the
Smarthome SecureLinc Wireless Home Security System (item # 72673903W). It can be
used to protect doors and windows using a built-in magnetic contact that
operates in conjunction with a magnet to detect the opening and closure of a
door or window. It is powered by a replaceable, long-life 3V Lithium battery.
The transmitter sends a "low battery" message to the receiver to alert you to
change the battery.
Auxiliary Input: The transmitter has an auxiliary hard-wired
input, programmable as either NC (normally closed) or EOL (end of line), for use
with additional sensors, such as pushbuttons, detectors, door contacts, etc. An
on-board DIP switch allows you to disable the magnetic-operated reed switch if
only the auxiliary input is needed.
PowerCode: When activated, the magnetic contact and the
auxiliary input initiate an individual 24-bit PowerCode ID message, which
identifies it to the target receiver as a separate transmitter. Each ID code is
randomly selected from 16-million possible combinations, and is therefore unique
and virtually impossible to accidentally reproduce. In addition, a smart,
anti-collision algorithm prevents signal jamming by simultaneous transmission
from multiple devices. Periodic transmission of supervision signals is used to
confirm system connectivity at all times.
Tamper Switch: The unit has a tamper switch which is activated when
the cover is removed. A tamper report is sent every 3 minutes until the tamper
switch is restored.
Supervision Message: A periodic supervision message is transmitted
automatically. The target receiver is thus informed, at regular intervals, of
the unit's active participation in the system.
LED: An LED lights whenever alarm or tamper events are reported. The
LED does not light while a supervision message is being transmitted.
