2.4. RF Detector Switch Set-up
2.4.1. RF Detector Switch LED Indicators
The MAXNET II MPRFA/B RF Detector Switch has three LED indicators: PWR, A and B.
a) The PWR (Power) LED verifies that the RF Detector Switch module is receiving power from the
MAXNET II Power Supply through the 24 VDC Chassis Bus. The PWR LED is always solid green when the module is
powered. If no powering is available then the PWR LED is off. The PWR LED does not have a flashing condition.
b) The A LED indicator will:
i) be green if RF on input A is above the software set threshold and the switch is currently on position A.
ii) be off if RF on input A is above the software set threshold, but the switch is currently on position B and the
default position is set to B in software.
iii) flash red if the power is below the threshold, or if the switch position is not the same as it’s
default position.
iv) flash red/green if the switch is on position A, but the module has some other alarm.
c) The B LED indicator will do the same as the above, but switch the A and B designators.

If the ALM LED is flashing red at a slow rate of approximately 1s on-1s off, this is indicative of a communications failure between this module and
the chassis. See Troubleshooting section.
