The internal pushbuttons can be used to view the dynamic state of all signal inputs by
pressing and holding the internal Test pushbutton for 10 seconds.
LED-1, located above the test pushbutton, slow ashes to indicate the Annunciator is in
monitor mode.
Whilst in this mode the individual channel LED provides the dynamic status of the
associated eld contacts.
• If the LED is ON the eld contact is CLOSED.
• If the LED is OFF the eld contact is OPEN.

used during commissioning or fault nding.
The contact monitoring function times out after 1 minute and the unit automatically
returns to the normal run mode and LED-1 reverts to steady ON.
