Signal Level Requirements - EMS FireCell Programming Manual

Signal Level Requirements

To ensure the signal levels for each wireless device and each RCC are at an acceptable level the Global
Sig Stat menu should be checked. This menu will display the signal levels in dB for each wireless device
and RCC over a 24 hour period. This is listed in Loop and Address Number order. After the system has
been running for a 24 hour period the signal levels should display 20dB or above. If any devices are
under the signal level requirements, check the owchart On How to Improve Device Signal Levels
section for guidance.
