3.4.7 Auxiliary Relay Outputs
-
The small enclosure is used for the DXc1 Series panels.
EN54-2: 8.8
Fault Output:
Relay 1 is configured
for failsafe operation
as standard.
EN54
!
-
Relay 1 (FAULT) is normally held in an energized state. It
will de-energize under fault conditions.
-
The DX Connexion Series Fire Alarm Control
Panels have three, unsupervised, relay
outputs, with volt-free (dry contact) changeover
contacts.
-
These are assigned to Fault, Fire Alarm and
User Programmable conditions respectively.
-
Each output is rated at 24V AC/DC, 1 Amp,
0.6PF.
-
Connect the screen drain wire to the nearest
earthing point in the enclosure – see loop-
wiring section for example.
Do not connect any wiring to the relay
contacts that is not power limited.
Route wiring away from power limited
signal cables.

3.4.8 Auxiliary Supply Outputs
-
The DX Connexion Series Fire Alarm Control
Panels have two power-limited, unsupervised
auxiliary (AUX O/P) 24V-output supplies rated
at 250mA each/ 250mA total maximum for both
circuits.
-
The normal AUX 24V can be used to power
Remote Annunciator (Repeater) units and other
peripheral loop units or other signalling loop
units.
-
The Switched AUX24V is switched (turned off)
on reset for ‘5’ seconds. This reset period is a
requirement of input devices such as flame or
beam detectors.
-
Shielded cable should be used for all AUX
circuits.
-
Refer to
Appendix 1 Specifications
for a list
of recommended cables.
-
Connect the screen drain wire to the nearest
earthing point in the enclosure – see loop-
wiring section for example.
