4.2.1
Loop status LED
The loop status LEDs (paragraph
4.2 - [B]
and paragraph
4.2 - [C]
) provide visual information relating to
the communications between the control panel and its detectors. They indicate that the panel is
interrogating its devices, the protocol it is using and whether or not the interrogated devices have
responded.
• The green LED on the right will flash each time a loop device responds. The control panel interrogates its
devices at regular intervals, starting from address 1 through to the last address (for information
regarding which devices can be connected to the loop, refer to
Appendix A
,
Appendix B
and
Appendix C
).
• The red LED in the centre will blink each time a command is sent through the loop for a device using
either Enea (
Appendix A
) or Argus (
Appendix B
) protocol.
• The red LED on the right will flash each time a command is sent through the loop for a device using
Apollo (
Appendix C
) protocol.
Under normal operating conditions, the red LED (relating to the protocol in question) will blink rapidly and
the green LED will flicker indicating the device response. The flickering phase depends on the number of
devices connected to the loop. The more devices the longer the LED will flicker.
4.3
LED panel
SmartLoop/P control panel models are equipped with a LED panel (located on the front of the control panel
enclosure) which is connected to the keypad/display board (paragraph
4.1 - [C]
).
This panel has 48 red LEDs which provide one or more signals (configured during the programming phase).
The On/Off logic of each LED can be set up individually.
[T]
PL
PL and GND terminals for disconnected-battery signalling In the event of primary and
secondary power failure (mains and batteries), the PL terminal will connect to GND. Under
normal operating circumstances, the PL terminal is disconnected.
[U]
AUX
24V output for the external power load, protected by a 1.8A self-resettable fuse
[V]
AUX-R
24V output for external loads, protected by a 1.8A self-resettable fuse (with "Power Cutoff"
during reset.) Suitable for powering devices which require power loss in order to reset (e.g.
beam detectors)
[W]
RS485
REPEATER
RS485 Bus terminals for repeater connections (accommodate up to 14 Repeaters)
[X]

ALARM NAC
Supervised alarm NAC output protected by 1A self-resettable fuse
[A2]
NAC1,
NAC2,
NAC3
Programmable NAC outputs protected by 1A self-resettable fuse
[A3]
