Question 5

What RF antennas are available for Australian fire alarm monitoring panels?

Accepted Answer

Xtend Communications supplies the DG900MB-HG High-Gain Multiband Omni (680–960 and 1710–2700 MHz, 7 dBi across 700–1000 MHz) for fire alarm monitoring applications. This antenna is the preferred RF component for Centaur and Centair 2 monitoring modules used across Australian fire and security monitoring networks. The 7 dBi low-band gain makes up for cable losses in plant room and rooftop installations.
