Control Buttons (internal) - Four pushbuttons give access to current and latched display information,
operator functions and to the programming facility (described later):
“Current Defects” shows all defects currently present.
“Latched Defects” shows all defects since last Panel Reset, including those currently present.
“System Status” shows current status conditions (including groups and switches).
“Function” gives access to the Function menu (see “Function Menu” and descriptions below).
In some menus, buttons have a slow/fast automatic increment mode if pressed and held.
Panel Reset - To clear latched conditions, modes, and indications, select Panel Reset (Pr) on the Function
Menu and press "Select".
Self-Test - Self-Test (St) is selectable on the Function menu. Press "Select" to commence test.
Self-Test automatically performs internal RAM and EEPROM checksum tests, and also exercises all
zone circuits. Order of testing (indication in brackets): (St), 1 - 8 Alarm (A), All Normal (n), 9 - 16 Alarm
(A), All Normal (n), All open-circuit (o), All Normal (n), then each enabled zone individually short-circuit
and back to normal (1), (2), (3) etc. to (16); (St) flashes until all RZDUs complete their test.
Self-Test failure results in a pulsing buzzer and failure code display (see “Self/Auto Test Failure Codes”)
Self-Test will not run (long beep) if there is a Fire or Defect indication (latched or current), or if a brigade
connected panel is not Brigade Isolated or in Brigade Test. Non-brigade calling zone circuits in offnormal conditions are omitted from the test, but do not prevent it from running.
Automatic Test - An automatic version of the Self-Test runs at the beginning of every daily charger inhibit
period. This can be initiated manually by selecting "Ci" on the Function menu.
Lamp Test - To initiate a lamp test select (Lt) on the Function menu. Press any button to cancel.
The door may be closed during a lamp test.
Non-Latching Test (NLT) Mode - NLT (walk test) mode (nL) is selectable through the Function menu.
A double beep every thirty seconds and an "nL" displayed, indicates entry into this mode. All enabled
zone circuits are temporarily set to indicating, non-latching, bell-ringing, non-brigade calling, with no
delays or gating regardless of their programmed selection.
In NLT mode, when any circuit is placed into alarm, its zone indication is latched on with the most recent
type of alarm, and the evacuation (Bells) output is activated for 0.5 seconds. Groups and ancillaries do
not operate.
A long beep indicates NLT mode cannot be entered - this could be a Fire or Defect condition (latched
or current), or if a brigade-connected panel is not Brigade Isolated or in Brigade Test. Panel Reset clears
NLT mode.
History Recall - History Recall is an interrogation feature available in the Function menu.
The most recent 15 significant events per board are stored in chronological order in RAM and will be
lost if power fails. There is no time/date "stamping". (See “Display Codes” for details of operation).
Zone Isolation - Individual zone isolation/de-isolation (toggle function) is available on a board-by-board
basis in the Function menu. Isolated zones are indicated on the displays. Power failure will clear.
