Custom Electronics AOV Multi Zone - Manual (Page 13)

7) Connection Guide
1.1 Actuator Connections
Each actuator requires a 2 core cable wired direct to the control panel and each pair must be connected to its
relevant zone via the terminal blocks numbered J28, J34, J40, J46, J52 on the zone distribution PCB. (This PCB
is numbered CUS-268A)
Refer to section 4 diagram 1 which shows the actuator connections labelled “LOAD” at the top of the PCB.
1.2 Smoke Detector Connections
Each smoke detector requires a 4 core cable which can be wired individually back to the control unit or can be
“daisy chained” in and out back to the control panel. 2 cores are required for the power (24vdc +Ve/-Ve) and 2
cores for closed circuit switching.
Refer to section 4 diagram 1 showing the connections. The detector 24Vdc supply is taken from the terminals to
the left side of the PCB labelled ‘24V output’ - observe polarity! The other 2 cores from the detector are
connected to relevant zone at terminals labelled “Link” at the top of the circuit board. As many smoke detectors
can be used as required providing a SERIES connection closed loop is created between each detector. Each
‘Link’ terminal fires its own zone actuator.
1.3 Standard Call Point – VCS-001
The standard yellow manual control point comes with “Break Glass” element.
These units require 2 core cables which are also connected to the ‘LINK’ terminal blocks in the control panel.
These can be installed as a stand alone unit on each zone or connected in SERIES with a smoke detector or
other call points.
NOTE: The LINK connection terminal blocks are 24v + positive and it is essential that no negative wire should
be applied to these terminal blocks or the power supply/AOV board will be seriously damaged.
1.4 Manual Control Unit Yellow with Open/close illuminated switches. – VCS-002
The manual control point is a feature only available with the extra manual control circuit board. For the multi-
zone configuration the AOV system must be ordered with the “Manual Control” PCBs fitted in the unit as an ex-
works optional extra. The call point requires a 5 core cable.
These connections are label: Negative, Open, Close, Power LED, Manual LED.
These connections are common throughout both the manual control point and the manual control circuit board
and correct wiring MUST be observed with close attention.
1.5 Keyswitch Yellow Call Point – VCS-003 (open/close)
The keyswitch yellow manual control point is fitted with an open and close key switch.
This unit requires a 2 core cable which is also connected to the ‘LINK’ terminal blocks. They produce the same
input to the AOV board by turning the switch as a smoke detector activating. This can be installed as a stand
alone feature for each zone or connected in SERIES with the smoke detectors.
NOTE: The LINK connection terminal blocks is 24v + positive and it is essential that no negative wire should
be applied to these terminal blocks or the power supply/AOV board will be seriously damaged.

1.6 Keyswitch Call Point yellow – VCS-004 (auto/open/close)
The fire override call point comes with a three position key switch. These positions are AUTO, OPEN and
CLOSE. In its standard AUTO position the AOV will perform in it usual manner. If the Key is turned to OPEN,
all zones will open regardless of the state of any other trigger input connected to the system. If the key is turned
to CLOSE, all zones will close regardless of the state of any other trigger input connected to the system.
NOTE: The AOV main board includes an on board override switch to CLOSE the outputs as an aid to
commissioning and service. This is located on the lower left of the board labelled ‘Fire Override’ (SW1).
1.7 Illuminated switch Call point – VCS-005 (open/close)
• Observe 4 wires, red – positive, black – negative, blue – switch.
• Connect red and black cables to 24V outputs (- , +) J3-J7.
• Connect blue cables to upper Link terminals for individual triggering.
• Connect blue cables to left Link terminals for multiple triggering.
Further information can be obtained from the Commissioning Manual.
