Circuit Description/Function
TPCA34 –SZAOV Master Card
PSU (- - + +)
Monitored 28VDC input from power supply module. Diode protected for reversal and
independent short circuit. Maximum input current, 5 Amps. Input voltage 22 to 32VDC.
DETECTOR (- +)
Conventional / Twin Wire fire alarm zone circuit input (latching by default). Monitored via a
6K8 end of line resistor. Monitoring current limit is 50mA, fused at 500mA. Up to 20
detectors may be used on this circuit. These may use schottky diode bases for detector
removal monitoring, ensuring that if a detector is removed, other devices on the cable are
still functional.
The circuit can be used in ‘Twin Wire’ mode by selection of DIL switch 4 on the main PCB.
This allows use of 24v alarm sounders in reverse polarity on this circuit. Note: In this mode
the detectors require special ‘Sav-Wire’ bases.
An alarm on the detector circuit will activate the vent outputs, in the same way as activation
inputs from the Fireman switch, local vent control switches, or other activation inputs.
Some programming options are available for this circuit, please refer to the programming
and set up section.
OPEN (- +) | CLOSE (- +)
Fused motor drive inputs from an external fire or SZAOV panel, not normally powered (non-
latching by default). Used to force the vent either open or closed, depending on its current
condition, when the external panel goes into an alarm condition.
Alarm activating input; 2K7 alarm, 6K8 Ohm, 5% 0.25W, EOL resistor. Monitoring current
limit 14mA, unfused.
MANUAL (CL COM OP)
Control inputs for manual operation of the vent by a local 3-way control switch. Moves the
vent by 10% increments when activated for less than 3 seconds, otherwise the vent is fully
operated.
•CL –Close vent
•COM - Common reference
•OP –Open vent
These inputs can be configured to also operate as a thermostatic control of the vent.
Replace the 2K7 resistor in the diagram above with a 10K resistor and the vent will open or
close to a pre-configurable position.

Single zone AOV User Manual PRODUCT OVERVIEW
17
Approved Document Ref: UI-SZAOV-01 Issue 2.01
FIREMAN (CP COM OP)
Control input from external 3-way fireman control switch, for manual control of the vent:
•CL Activates the vent output (fully close vent)
•COM Common reference
•OP Activates the vent output (fully open vent)
In default condition, operation of this switch will fully open/close the vent, overriding local
switch settings/vent positions.
Note: If neither input is activated, vent follows panel automatic control.
ACT (+ -)
Dual polarity reversal vent drive actuator outputs - 28VDC, max 8A, protected by a current
trip circuit. Not normally powered. Operated by the inputs from either the main fireman
switch, or the local vent control switch; for a configurable time-period of 10 to 300 seconds.
The default setting is 60 seconds, during configuration of the panel, this should be set to the
time-period required to open/close the vent fully. Polarity is reversed for vent closure.
The resistance of the actuator is monitored. When above 10KΩ it is considered an open
circuit and less than 10Ω it is considered a short circuit. This monitoring is only active when
the actuator is in the fully open or fully closed position. A configuration option allows the
short circuit monitoring to be completely suppressed. This option might not meet the
requirements of local regulations. When used in this mode, connecting resistances of less
than 1Ω can cause damage to the circuitry of the actuator driver.
On commissioning, the vent should be set to the fully closed position prior to connection.
The actuator outputs may be changed to a continuous, maintained operation using DIL
switch 3, ‘ACT POWER’. The control logic can be inverted using DIL switch 1, ‘ACT
INVERT’.

AUX (+ -)
A maintained magnetic vent 28v output for external magnetically controlled devices.
Switches off to release magnet in the alarm condition. The output can be inverted using DIL
switch 2 ‘AUX INVERT’ on the main PCB.
May also be used as an alternative vent auto close output.
FIRE (NO NC COM)
Common alarm changeover relay contacts, max 3A at 30VDC (unfused). Activates when an
alarm condition exists on the open/close input or detector circuit.
FAULT (NC NO COM)
Common fault signal changeover relay contacts, max 3A at 30VDC (unfused). Normally
energised (failsafe) contacts change-over when any fault is active on the panel or in the
event of total power loss.
SENSOR (+ -)
Connections for battery temperature sensor.
BATTERY (+ -)
Output connections for 7Ah 12Volt batteries charging (temperature compensated). 27.3VDC
output at 20C, Max. charging current: 700mA.

PIR/BMS Plug-in Card (2-Way) –PIR-0-10-3041-212 (TPCA029) (Optional)
Although the PIR card is designed as a two-way card, when used on the SZAOV panel only
one side of PIR and BMS connectors can be used. This means only one PIR can be fitted in
the system.
PIR 1/PIR 2 (+ -)
The PIR input is available to monitor a typical security type PIR with N/C alarm and tamper
contacts. The PIR requires a 12VDC supply, taken from the boards 12V output. The input
requires a 10KΩ impedance to trigger, with a 6K8Ω 5% 0.25W EOL resistor. Monitoring
current limit is 14mA, unfused.
When operated, the PIR alarm prevents the vent from closing to guard against entrapment
injury. The PIR should be mounted in accordance with the manufacturer’s instructions, to
detect any presence in the vicinity of the entrapment risk.
BMS 1/BMS 2 (0V IN OUT)
Building Management System control interface, using 0-10 volt proportional control signals:
•0V –Common 0V output. This is 0 volts common reference for 0-10V input and
output
•IN –Positional voltage input. Accepts 0-10 volt (DC) signal in 1 volt steps per 10% of
motor time. Vent position is determined by running time, which by default is 60
seconds, i.e. 10% = 6 seconds running time, 50% = 30 seconds etc. Max input is
10VDC, with 75kΩ impedance.
•OUT –Positional voltage output. This output represents the position of the vent in
10% steps of motor run time. Provides feed-back of the 0-10V input status and vent
positional information. Max output is 10VDC 2mA. Max 20KΩ load and 680R
impedance.
RAIN (+ -)
Signal input from wind/rain sensors. Typically, a wind/rain sensor will have a closing contact
alarm signal and may require a 24V supply. The input requires a 2K7Ω impedance to trigger,
with a 6K8Ω 5%0.25W EOL resistor. Monitoring current limit is 14mA, unfused. Any one of
the wind/rain sensors can close a manually opened vent but will not override an alarm signal
input.
