MGC DSPL-420-16TZDS Main Display or Control Interface
DSPL-420-16TZDS
The DSPL-420-16TZDS is a main display / control interface for a main panel in
a FleX-Net, MMX, or a classic FX-2000. It is designed to mount in any standard
display window cut out found on the doors in the FleX-Net, MMX, and FX-2000
series. This display is functionally equivalent to the FleX-Net and classic
FX-2000 main display, but more compact.
The DSPL-420-16TZDS has a 4 line, 20 character back-lit LCD display with 4
cursors buttons and an Enter button to navigate the LCD menu items, as well as
Menu, Cancel and Information buttons. The display also features 16
configurable bi-coloured LEDs, 4 Queue Buttons with LED Indicators, and 8
control buttons, each with it’s own LED Indicator. The display also includes
LEDs to indicate AC On, Ground Fault and CPU Fault.
Indicators and Controls
Figure 1 Indicator and Control locations on the DSPL-420-16TZDS
LED indicator are amber (trouble or supervisory), red (alarm), or green (AC On), and may illuminate continuously (steady) or at one of two flash rates:
- Fast Flash: 120 flashes per minute, 50% duty cycle
- Trouble flash: 20 flashes per minute, 50% duty cycle
Note: The General Alarm LED and pushbutton, and the Automatic Alarm Signal Cancel LED and pushbutton, are active only on a system configured for “Two Stage”.
Paper Labels for Buttons and Indicators
Buttons and indicators are supplied with paper labels. These labels slide into
the plastic label templates on the face of the panel. Paper labels allow for
easy English / French selections and custom printed zone information.
Common Indicators
| Indicators | Description |
|---|
Buzzer
| The Buzzer is activated by any of the following:
Fire Alarm – Steady Supervisory Trouble – Fast Rate Trouble – Trouble Rate
Monitor – Configurable for silence or for sounding at the Fast Rate.
Note: To meet UL-864 requirements, set the Monitor buzzer for silence.
If the Buzzer is turned on in response to a Non-Latching Trouble or Supervisory, it will be turned off if the condition causing it goes away and there is no other reason for it to be on.
AC On LED
| The AC On Indicator is activated steady green while the main AC power is within acceptable levels. It is turned off when the level falls below the power-fail threshold and the panel is switched to standby (battery) power.
Alarm Queue LED
| The common Alarm LED flashes red whenever the Panel is in Alarm. An alarm results from any alarm on any point or input programmed as Alarm or activation of the manual red General Alarm Button (if the panel is set for Two Stage Operation). The Alarm Queue LED will go steady, once all alarms in the queue have been reviewed using the Alarm Queue button. Since all Alarms are latched until the Panel is reset, the Common Alarm LED will remain on until then.
Supervisory Queue LED
| The Common Supv. (Supervisory) LED flashes amber at the Fast Flash Rate when there is a Supervisory Alarm in the Panel, as the result of any Latching or Non-Latching Supervisory Circuit. The LED turns off if all Non-Latching Supervisory Circuits are restored and there are no Latching Supervisory Circuits active. The Supv. Queue LED will go steady, once all supervisory alarms in the supervisory queue have been reviewed using the Supv. Queue button. Latching Supervisory Alarms remain active until the Panel is reset.
Trouble Queue LED
| The Common Trouble LED flashes amber at the Trouble Flash Rate when there
is any Trouble condition being detected on the panel. It is turned off when
all Non-Latching Troubles are cleared. The Trouble Queue LED will go steady,
once all troubles in the trouble queue have been reviewed using the Trouble
Queue button.
Monitor Queue LED| The Monitor Trouble Indicator flashes amber at the
Trouble Flash Rate when there is any Monitor condition being detected on the
panel. It is turned off when all Monitors are cleared.
CPU Fault LED| ****
The CPU Fault Indicator flashes yellow if the CPU is faulty.
Fire Drill LED| The Fire Drill Indicator turns on steady amber while the
Fire Drill is active.
Automatic| If the Panel is configured as Two Stage, the Automatic Alarm
Signal Cancel Indicator flashes amber at the Fast
Alarm| Flash Rate while the Auto General Alarm Timer is running. It
turns on steady amber when the Timer is cancelled by
Signal| activating the Automatic Alarm Signal Cancel or Signal Silence
buttons. If the Auto General Alarm Timer times
Cancel LED| out and puts the Panel into General Alarm, the indicator
is turned off.

General Alarm LED
| In Two Stage Operation only, the General Alarm Indicator is activated
steady red when General Alarm is activated due to the red General Alarm button
being pushed, a General Alarm Initiating Circuit being activated, or the Auto
General Alarm Timer timing out. Once the General Alarm Indicator has been
turned on, it will stay active until the Panel is reset.
Signal Silence LED| The Signal Silence indicator is flashed amber at the
trouble rate when the Indication Circuits are Silenced either by the Signal
Silence button, or by the Auto Signal Silence Timer. It is turned off when the
Signals are re-sounded by a subsequent Alarm.
Ground Fault LED| The Ground Fault Indicator flashes amber at the
Trouble Rate when the Ground Fault Detector detects a Ground Fault on any
field wiring. It turns off immediately when the Ground Fault is cleared.

Queues are displayed on the screen according to a priority sequence. Queue priority ranking from highest to lowest is as follows: alarm, supervisory, trouble, and monitor. If, for example, you are viewing a monitor queue and an alarm occurs, the display will immediately display the alarm condition. Also, if there is no activity on the system for 10 seconds after you have pressed a queue button, the display will switch to the highest priority condition.

Signal Silence Button
| Activation of the Signal Silence button when the Panel is in Alarm turns on
the Signal Silence Indicator and deactivates and Silenceable NACs. Non-
Silenceable Circuits are unaffected. Signals will re-sound upon any subsequent
Alarm. This button does not function during any configured Signal Silence
Inhibit Timer period. It also does not function if the NACs are active as the
result of a Fire Drill. In a Two Stage System, if the Auto General Alarm Timer
is running, the Signal Silence button also performs the same function as the
Automatic Alarm Signal Cancel button.
Fire Drill Button| The Fire Drill button activates all programmed and
non-Disconnected NACs, but does not transmit any Alarms via the City Tie, or
Common Alarm Relay. Fire Drill may be programmed to operate specific NACs.
Fire Drill is cancelled by pressing the button again (toggle switch), or if
the Panel goes into a real Alarm.
Automatic Alarm Signal Cancel Button (Two Stage Only)| If the panel is
not configured for Two Stage Operations, this button does nothing. If the
Panel is configured for Two Stage Operation, activation of the Automatic Alarm
Signal Cancel button while the Auto General Alarm Timer is running (there is
an Alarm in the Panel, but it is still in the First Stage), that timer is
cancelled, and the Automatic Alarm Signal Cancel Indicator is on steady amber.
General Alarm Button| If the panel is not configured for Two Stage
Operation, this button does nothing. If the Panel is configured for Two Stage
Operation, activation of the General Alarm button immediately sends the Panel
into Second Stage — General Alarm. It will also re-activate the Signals if
they have been Silenced during General Alarm. The General Alarm condition
remains active until the Panel is reset.
Visual Indicator Test Button| Activations of the Visual Indicator Test
button turns on all front panel Indicators on steady in whichever colour they
would normally be activated and turns on the buzzer on steady. If the Visual
Indicator Test is active for more then 10 seconds, Common Trouble is
activated.
