Common Faults:
Devices not learning in?
•
The No.1 reason is Frequency. Confirm Dipswitch 3 & 4 are set correctly for the desired frequency.
The Dipswitches are only assigned on power up, so a power/down, power/up many be required.
A simple Test is to look at the RX-16 and trigger your wireless device. LED 1 should turn on Green.
If the LED doesn't turn on, its not on the correct frequency or there is a connection problem.
Note. The LED turning on doesn't mean the device is learnt in, just that it is being detected by the RX-16.
•
Wiring could be a problem, because the RX-16 is connected to the keypad bus you can use your multi-
meter to measure the voltage to the terminals. Please use the same Voltage tests as showing in the Key-
pad Bus Checking page.
Another simple test is to look at the RX-16 when trying to learn in, LED 1 will flash in sink with the key-
pad beeps. If the LED doesn't flash there is a communication problem.
•
A device can only be learnt in once, so if you try to learn the same button or PIR into a different slot the
Elite-S system wont let you. What you can do is a search for loaded Pendants and Detectors.
The Programming address for Users/Pendants is P 20 E 0 E (when beeping starts trigger device)
The Programming address for Zones/PIR is P 166 E 0 E (when beeping starts trigger device)
If the device is loaded the slots number will flash up on the display.
Poor Range?
•
The No.1 cause of poor range is RX-16 location.
Ideally the RX-16 should be mounted in a elevated position and away from metal objects.
Inside a plastic box is fine, but in a metal cabinet is bad, even if the antenna is put externally.
•
Other Wireless equipment can cause problems, watch out for wireless doorbells & garage door openers.
Unplug them and try again, switching to another frequency may fix the problem.
Cellphone towers, Radio transmitters and Power pylons can be a problem, try another frequency.
Adding more RX-16’s in different locations will increase your wireless coverage.
