![]() If the output is being used remove the wires from O1 and AUX+ and measure the resistance of the wires.If the output is not being used make sure a 1K resistor (brown, black, red) is connected between O1 and AUX+.Put a 1K resistor (brown, black, red) across Bell+ and Bell- to verify the trouble condition clears.Īn open circuit is present on output #1 of the PC5204 module.If an open circuit is measured there is a break in the wiring or the siren is defective. Ensure the module is getting proper AC power.If an open circuit is measured there is a break in the wiring or the device connected is defective. ![]() Remove all devices connected to the AUX+ terminal of the PC5204 and measure the voltage between AUX+ and BLK of the KEYBUS.Measure across the two AC terminals of the module and ensure the AC input is between 16 and 18VAC. Modules are immediately enrolled and supervised when detected on the KEYBUS.The panel has lost communication with one or more modules on the KEYBUS or a keypad has been assigned to a different slot If the tamper input on the modules connected to the KEYBUS are not being used, connect a short between the Tamper terminal and COM on every module (PC5100, PC5108, PC5200, PC5204, PC5208, PC5320, PC5400, PC5401, PC5700).To disable RF Jam enable Option in Program Section, subsection Īn open circuit is present on the tamper input of one or more modules.Check the installation for other sources of 433MHz wireless signals (could also be nearby transmission tower, airport, military base).The wireless receiver has detected excessive noise in the 433MHz range (Power432, 632, 832 only) Check the connected printer for trouble (no power, out of paper, jam etc…).The printer connected to the PC5400 is off-line If the voltage is below 13.75VDC the module is defective. To reset module supervision enter Program Section.View the event buffer (via DLS or LCD5500 keypad) to view the specific module(s) in trouble.If a module has been removed, or if the slot assignment of a keypad has been changed, module supervision must be reset. The wireless receiver has detected excessive noise in the 433MHz range (Power864 only) To view what modules are connected to the KEYBUS enter Program Section.Press and wait 1 minute for the panel to rescan the KEYBUS. With the battery connected remove AC from the module and measure across the battery terminals.The trouble condition will not clear until the battery is at least 12.5VDC under load. ![]() The phone line voltage across the main panel TIP and RING terminals is less than 3 VDC Trouble – Telephone Line Trouble Secondary Trouble Measure across the two AC terminals of the panel and ensure the AC input is between 16 and 18VAC.No AC present across the panel AC terminals Measure across the two AC terminals of the module and ensure the AC input is between 16 and 18VAC.If the voltage is below 12.5VDC replace the battery.
