CONNECTING ALARM DEVICES
The 95/TX provides three SPDT alarm relay outputs and one dedicated fault relay output. Terminals are
labeled “NO” (normally open), “NC” (normally closed) and “C” (common) and are located on the power
supply board located in the back of the enclosure. The power supply board also provides contacts for a
remote “alarm acknowledge” button. Power for 24V strobes or horns can be taken from spare “+” and “-“
pins on TB1.

ANTENNA SELECTION
MONOPOLE AND COLLINEAR OMNI-DIRECTIONAL ANTENNAS
The 95/TX Wireless Alarm Station includes a standard “rubber duck” omnidirectional antenna. “Omni”
antennas are the most commonly used antenna for portable and semi-portable equipment. When
mounted vertically, they provide good all-around (“omnidirectional”) reception and transmission from
horizontal directions, and are generally rugged and when sealed properly against moisture can provide
years of quality service.
The 95/TX is also available with a flexible omnidirectional antenna that is more resistant to damage in
field applications. The flexible antenna offers the same gain and reception pattern.
Collinear antennas are similar in appearance to ‘rubber duck’ antennas, but are more sophisticated and
combine several vertical antennas that operate in parallel to increase signal gain by focusing the reception
pattern in a more horizontal plane. Collinear antennas should be used where additional signal gain is
required.
