▪ Keypad Test
▪ Ext Comm Loop Test (see “Appendix 6 - Connection to Other Devices” for details)
▪ NRM Relay Test (tests the relays on any connected TT-NRMs)
▪ Ground Fault Test
The Self-Test menu is password-protected to prevent inadvertent emergency response
activity, because in many installations the leak relay or 4-20 mA output may be connected
to external systems. Always notify the appropriate response personnel before using the
Relay Test or 4-20 mA Test to alter their outputs.
The rst three tests are also accessed by pressing the Test key when the display is in the
Current Event/Status Display mode. This key is not password protected.
