Chapter 11 Page 11 - 11
H: OUTPUTS WIRING
When wiring outputs, do NOT exceed the maximum rating
for individual outputs, or for the system power supply.
(i) SAB Connections
OUTPUT RATING
Strobe and Siren Outputs are
rated for 800mA each. Note
that the 'Hold Off' fuse is rated
as 800mA. This may be
upgraded to 1.25A (only on End
Stations with PSU of 1½ Amps
or higher) with care, ensuring
that the total current drain
does NOT exceed the maximum
rating of the power supply.
Ensure that the system power
supply is not overloaded.
NOTE for Euro-44+ Issue 1 PCBs
only:
Whilst the Strobe and Siren outputs
are capable of powering up to 800 mA
individually, the combined loading of
these outputs must NOT EXCEED
800mA.
The maximum current that can be
drawn from the Hold Off terminals
(B4,5) is 650mA continuously, or
800mA for the duration of an alarm
only.
If a higher current sounder is to be
used, and which draws all current from
the Hold Off connections (ie uses the
‘Siren’ feed solely as a ‘trigger’), the
additional current may be supplied by
using terminals H9,10 for the Hold Off
connections, and uprating fuse F1 to a
suitable value – eg 1.0 or 1.25 Amps.
Current Available:
O/p 1 (Siren):
800mA
O/p 2 (Strobe):
800mA
Hold Off:
800mA
Note tamper return is
NEGATIVE.
On Euro
-
44+ issue 1 End
Station PCB there is NO
fuse to remove to test
SAB action.
