Installation Guide LF Location Units TD 92082GB PRELIMINARY 1 Introduction Figure 1. L951LP Locator, L951A1 Antenna Unit and L951A2 Antenna Unit. The Locator L951LP is a dual output low frequency (LF) inductive location transmitter. It is used in the Ascom Paging System and Ascom IP-DECT System, when location function is required. It generates coded signals to modulate a magnetic field carrier. Alarm Transmitters designed for LF can be used to identify the location from where an alarm is generated.

Installation Guide LF Location Units TD 92082GB PRELIMINARY 3.5 Locator Monitoring The monitor output is a galvanically isolated relay contact (< 15 ohm) used for supervision of the locators. The relay contact becomes open circuit (> 1 M ohm) if a fault is detected. It can be a collapse of the magnetic field due to a discontinuity in the antenna loop, or the tamper protection has been triggered.
Installation Guide LF Location Units TD 92082GB PRELIMINARY Depending on the type of Alarm Module and the supply voltage in the monitor loop, the following number of units can be connected to the same input: 3 4 Supply Voltage 12 V DC 24 V DC T941AM32 Max no of units: 2 9 T941AM8 Max no of units: 5 12 Reed relay (SW03 on Locator and SW01 on Power Amplifier) is connected in series with the monitor output. The relay closes if a magnet is placed near to and parallel to it.
