TAMPER TROUBLE (XR PANELS ONLY)

TAMPER –TRBL displays when the enclosure is opened or removed or the tamper header goes open, resulting in a signal

transmission to the central monitoring station�

If this occurs when one or more areas are armed, a tamper ALARM message is sent�

If this occurs when all areas are disarmed, a tamper TROUBLE message is sent� The tamper header is

for use with an optional DMP Model 306 Tamper Harness� The harness connects to one or more tamper

switches mounted inside the panel enclosure to detect unauthorized opening or removal of the enclosure�

To clear TAMPER -TRBL from the display:

When the panel tamper is not being used, a jumper should be placed on both pins of the tamper header�

When the Model 306 is installed, place a jumper on the tamper header� Does the display clear?

YES - Close the tamper switch(es) and check the Model 306 for continuity� If harness or switches

are bad, replace the Model 306�

NO - Enter Programming and Initialize EVENTS� Exit Programming� If the trrouble does not clear

the panel needs to be repaired�

Note: Initializing EVENTS erases ALL EVENTS in the Event Buer�

WIRELESS TROUBLE

When WIRELESS -TRBL displays, it means that the panel has a House Code programmed in System Options and has

either lost communication with the 1100 Series Wireless Receiver, or the tamper switches on the receiver (1100X or

1100XH only) are not fully depressed�

To troubleshoot the cause on an XR panel, the X-BUS option in diagnostics will display the receiver’s ﬁrmware version if

the panel can communicate with it� Is the receiver ﬁrmware and date code displayed on the keypad?

YES - The panel is able to communicate with the receiver� Check the tampers on the receiver by pressing

the switches by hand�

NO - The panel cannot reach the receiver or the receiver cannot reach the panel� Verify the receiver is

connected to the panel correctly� On XR panels, use the X-BUS header� Check data bus voltages� If there

is an open or short on the line, bring the receiver back to the panel and connect it using a short wiring

harness and verify the WIRELESS -TRBL message has cleared�

XT panels do not have the ability to test communication with the wireless receiver from the keypad� Voltage at the panel

and the receiver can test the connection between the two� Wireless receivers connect to the keypad bus terminals (7-10)

on the panel�
