The Elpas Low Frequency (LF) Exciter from Visonic Technologies is a supervised, short-range, UHF emitter that adds pin-point detection functionality to any Elpas safety, security or monitoring installation.
The LF Exciter is engineered to emit spherical, low-power electromagnetic fields (125 KHz) of up to 3 m (10 ft) in radius. These harmless LF fields are user-adjustable, so that they can be tuned to precisely cover most indoor doorways or entrance/exit areas. So, whenever an individual or asset bearing an Elpas active RFID tag enters the electromagnetic field generated by the exciter, the mobile tag is prompted to transmit its pre-programmed data messages (including the exciter’s Neuron ID). The messages are instantly detected by the Elpas RF reader infrastructure and are locally processed and/or relayed over the LonTalk network to the EIRIS server machine in support of the configured Elpas application.
The LF Exciter also includes an onboard UHF (433.92 MHz) transmitter, which continuously broadcasts real- time device supervision alert messages for keeping repair personnel informed of possible maintenance issues related to the device.
Architecturally attractive and unobtrusive, the Elpas LF Exciter is easily surface-mounted on solid walls and ceilings or flush-mounted into dropped (false) ceilings. The exciter is deployable as a standalone device, designed to cover normal interior single or double doorways or in a flexible master–slave configuration suitable for coverage in large, open indoor spaces.
