8.2
Mounting.
1
Remove front cover.
2
Hang the control panel base onto the wall with the central mounting hole using one of the screws and plugs
provided.
3
If possible use a spirit level or some other means to position the control panel squarely then drill the remaining
holes into the wall to locate the screws and plugs.
8.3
Mains connection.
1
The mains supply connector should be carefully wired to an ac mains supply using a suitably rated 3 core cable
with a current carrying capacity of not less than 5 Amps. It should be connected to a fused spur with a fuse rating
of not more than 2 Amps.
2
The mains connections at the power supply terminal block are coded as follows:
L
:
LIVE
:
EARTH
N
:
NEUTRAL
8.4
Battery capacity.
It is recommended that the rechargeable battery used with the Octagon II control panel should be capable of powering
the alarm system for a minimum of 8 hours, and that this time period include 20 minutes of bell/strobe operation.
The minimum battery capacity should be calculated from the current consumption of the individual system components.
A typical example is shown below:
Non alarm current for control panel ( 7 hrs 40 min)
:
174mA (0.174 A)
Steady state current for detectors
:
120mA (0.12 A)
(e.g. 8 x 15mA for 8 hours -Pyronix PIRS)
Typical stand-by current for external sounder
:
50mA (0.05 A)
(e.g. Self Actuating Bell for 8 hours)
Typical on state current for external
:
350mA (0.35 A)
sounder (20 mins)
Alarm state current for control panel (20 mins)
:
140mA (0.140 A)
Typical current for external strobe (8 hours)
:
150mA (0.150 A)
Total battery capacity
= (Panel stand-by current x 7hrs 40min)
+ (Detectors, SAB and strobe current x 8hrs)
+ (Panel in alarm with external sounder x 20mins)
i.e.
0.174 X 7.67HRS
+ (0.12 + 0.05 + 0.15) X 8HRS
+ (0.40 + 0.35) X 0.33HRS
~ 4.1 Amp Hours
For example it is recommended that you use a battery of not less than 4.1 Ah, the nearest size above this being 6Ah.
8.4.1
Battery Charging.
This Octagon II has a fast battery charge circuit capable of recharging a 6Ah battery in 12 hours
NB: 1)
Do not allow any cables or wiring to touch the battery charge resistor ( See diagram on Page 9 )
High resistor temperature during battery charging will damage insulation to wires touching this resistor, resulting in
incorrect operation of the control panel.
NB: 2)
Do not use a battery of less than 2.8Ah capacity
