HIGHEST RELIABILITY
Double modulation technology ensures stability and reduces the possibility of unwanted activations from ambient light.
COMPACT DESIGN
TXF-20TDM features a slim,
compact design with quick access to the wireless transmitter/battery holder for easy maintenance.
SAVES TIME AND MONEY
Designed for compatibility with leading wireless systems,
TXF-20TDM dramatically reduces the time and cost of installations by requiring no wiring or civil engineering work,
ideal for rapid deployment in temporary or permanent secure perimeter intruder detection systems.
LONG BATTERY LIFE
4×3.6V (17Ah) batteries (TX:2pcs, RX:2pcs) can power TXF-20TDM for up to 3 years of service,
with the option of battery sharing for wireless transmitter units.
OTHER FUNCTIONS
Enhanced features include a drip-proof housing designed to channel precipitation away from the face of the beam,
anti-bird spikes (option) to prevent our feathered friends from alighting on the units,
a sound check function for easy alignment, and lightning surge protection.
