For your safety:
This equipment is to be installed, serviced and maintained by a suitably qualified
technical person with the requisite knowledge of electrical and fire safety installations.
The Noby-65 is intended to be permanently connected to the 230VAC house wiring via a
2A fused spur and in accordance with local wiring regulations.
Part of the internal circuitry operates at 230VAC and presents an electrical shock hazard.
Do not attempt to open, dismantle, repair or tamper with this equipment without first
disconnecting the 230VAC supply voltage.
This is Class-1 electrical equipment and must be earthed.
Please read this Installation Manual carefully and retain for future reference.
We strongly recommend that the Noby-65 is first powered up with all 10K End Of Line resistors fitted at the panel,
as supplied by the factory. In this way you can gain confidence that the panel is operating correctly before
introducing detector and sounder circuits.

IMPORTANT: TAKE CARE TO CONNECT THE BATTERY CORRECTLY.
Whilst there is a measure of protection against accidental reverse connection of the battery, such action will almost
certainly blow fuse F3, and may cause permanent damage to the Noby-65 panel. Such damage is identifiable to
Noby UK Ltd. and is not covered by the warranty.
The PSU provides a regulated voltage rail of 13.6v (nominal 12v), with a continuous current rating of 1.5A, and a
20-minute rating of 2.0A. The PSU is designed to meet the internal standby power requirements of the Noby-65
and also to charge and maintain the 7Ah SLA battery in optimum condition. The battery standby time is dependant
upon the overall system current drawn, including all connected equipment. Also it is strongly recommended that the
continuous system standby current does not exceed 1.0A, because some reserve PSU capacity must be available
to recharge the battery following an alarm condition or a prolonged period of 230VAC power loss.
The Noby-65 enclosure can accommodate one 12v/7Ah SLA battery.
The PSU is monitored for loss of 230VAC power, low battery voltage, and a Battery-Condition load test is
performed every 12hrs. PSU faults are indicated by a flashing Power LED and the Fault LED, together with an
audible pulsing fault tone at the Buzzer output.
Always ensure that the maximum current drawn in alarm does not exceed the 3.0A battery fuse limit (F3).
The PSU is monitored for:
PSU Fault LED Status
i) 230VAC Absent or Fuse F2 blown: Power LED is off. (after a 10s delay).
ii) 230VAC Restored: Power LED flashes. (memory).
iii) Low Battery Voltage: Power LED flashes.
Fault LED is lit when the voltage <10.0v
iv) Battery-Condition or Fuse F3 blown: Power LED flashes
Fault LED is lit.
INPUT & DETECTION CIRCUITS
Figure 2 shows the detector wiring diagram for a typical residential alarm system.
Fire Detectors A03 & A04 24hr circuit. 24v optical & ionisation smoke, or rate-of-rise heat detctors.
Water Detectors A05 & A06 24hr circuit. Water float switches.
Sabotage Circuit
(Anti-Tamper)
A07 & A08 24hr circuit. This circuit Includes the Noby-65 lid microswitch.
End Of Line Resistors
The Noby-65 requires that all detection circuits be terminated with a 10K End Of Line resistor, to facilitate opencircuit fault monitoring. For maximum security the EOL resistors should be connected at the last detection device
at the end of each cable run, and for this reason it is advised to ‘daisy-chain’ the cable, with no ‘T’ junctions. Only
one EOL resistor is permitted on each circuit, such that in steady-state condition the Noby-65 sees a circuit
resistance of 10kohm. Any detection circuit not being used must have its EOL resistor connected at the Noby-65
terminals.
Auxillary 12v Detector Supply [A01,A02]
A 12V supply fused at F500mA (F2) is provided at terminals A01 & A02 to supply power for PIRs and other low
power electronic detection devices.
There are three intruder circuits: Zone-1, Zone-2 and Exit/Entry. Each detection circuit may comprise any
combination of:
i) door or window magnetic contacts.
ii) electronic detectors - PIR, ultrasonic or doppler-microwave.
iii) window foil.
iv) vibration or glass-break detectors.
v) pressure mats.
Zone-1 is the main intruder detection circuit, and is armed when the keyswitch is turned to FULL or PART.
Zone-2 is the secondary intruder detection circuit, and is armed only when the keyswitch is turned to FULL. Zone-
2 is normally used to protect the night-time living area in a house, such that the occupants can freely move around
without causing an alarm, whilst the rest of the house is protected in Zone-1.
Exit/Entry is the area covering the direct path between the Noby-65 and the final exit door. This circuit allows the
keyholder to safely leave the property within a preset Exit-Time. On re-entering the premises the Entry-Tone will
start, and the keyholder must proceed directly to the Noby-65 panel and turn the keyswitch to OFF. Straying off
the Exit/Entry route into an area protected by Zone-1 or Zone-2 will trigger an immediate alarm condition.
Electronic detection devices (e.g. PIRs) are powered from the Auxillary 12v supply terminals (A01 & A02), fused at
500mA (F2). Warning: do not to overload this 12v supply. As a rough guide each PIR draws 25mA. The latching
LED function of PIRs can be controlled by connecting the appropriate PIR terminal (often called SW+, Set, C or
Control) to the SW+ signal appearing at terminal B13. This signal is normally 0v and switches to 12v when the
Noby-65 is fully armed i.e. after the Exit-Time period. This SW+ signal can also be used to signal a System-Set
(Open/Closed) signal for Remote Signalling Equipment.
Pressure Mats must be connected between the two cores of the detection circuit, such that the EOL resistor
becomes short-circuit in alarm.
The cable for each circuit may require up to 7 cores: 2 cores for the alarm detection circuit, 2 cores for the detector
supply, 1 core for the SW+ signal, and 2 cores for the Sabotage circuit (Anti-Tamper). Any spare cores should be
used to ‘stiffen’ the detector 0v power connection.
Duress / Panic (Personal Attack) [A09,A10]
Activating the Duress / Panic Circuit will trigger a silent Duress response at signal output B12. A silent Duress
alarm is sometimes the preferred option for systems employing Remote Signalling Equipment. For personal safety
reasons Duress is the default mode of operation, as supplied from the factory. Alternatively, the Noby-65 can be
configured to give a full local audibles Panic alarm:
To configure the Panic Option:
i) remove all power from the Noby-65 – both battery and 230VAC power supply.
ii) press the Panic Button such that the Panic Circuit is open-circuit.
iii) reconnect the power supply to the Noby-65.
iv) reset the Panic Button.
v) reset the Noby-65 by performing a System Reset.
Important: the Panic option will revert back to Duress in the event of total power loss to the Noby-65.
Sabotage Circuit (Anti-Tamper) [A07,A08]
The Sabotage circuit protects the Noby-65 from criminal interference or accidental damage. This is a single circuit
and should be routed around all the intruder detection circuits, and through all lid switches. The Noby-65 is
supplied with an internal lid microswitch pre-wired and fitted with a series 10Kohm EOL resistor at terminal A08.
To insert new sabotage loops: First unscrew the wire at terminal A07, and then connect any newly created loops
between A07 and the free end of the microswitch wire. For typical installations it is recommended to leave the EOL
resistor in its original position at terminal A08.
Fire Detection Circuit [A03,A04]
The Noby-65 incorporates a low power 12v/24v invertor which permits the use of industry standard 24v
conventional smoke detectors. Any combination of conventional optical or ionisation smoke detectors, or rate-ofrise heat detectors can be connected. The total steady-state current taken from the Fire Detector terminals A03 &
A04 must not exceed 1mA. Typically this equates to a maximum of 10 detectors, assuming a rated current of
100uA per detector. The Fire Detector Circuit is monitored for open-circuit faults.
Water Alarm Detection Circuit [A05,A06]
This circuit is intended to accomodate water level float switches for use in flood detection. Once triggered the
Water Alarm Output can be used to shut off a water solenoid operated valve as shown in Figure 3.
Although this circuit is labelled ‘Water’, it can be used for other purposes e.g. a 24hr freezer alarm to give a
warning of rising freezer temperature.
Figure 3 shows the alarm outputs wiring diagram for a typical residential alarm system.
Intruder Alarm Relay Output [B01,B02,B03,B04]
The Noby-65 alarm siren output is provided at terminals B01 to B04. Terminal B01 is 0v, and terminals B02, B03
and B04 are a set of make/break relay contacts. For most installations a Siren will be driven from this relay, and
for convenience the centre contact is connected to 12v via fuse F5 on the PCB. This 12v feed can be diconnected
by removing fuse F5 – leaving a clean set of voltage-free contacts rated at 30V/2.5A.
This alarm output relay is activated for a preset Siren-Time, adjustable from 10s to 360s (P3).
It is recommended to use polarised sirens or bells fitted with a suppressor.
Fire Alarm Ouput [B05,B06,B07]
The following two fire sounder outputs are fused at F1A (Fuse F4):
i) the 24hr terminal (B05) gives a fire alarm at all times, even when the keyswitch is OFF.
ii) the 12hr (or SET) terminal (B07) activates only when the keyswitch is turned to FULL or PART.
Both terminals are open-collector pnp transistor outputs and switch to +12v during a fire alarm condition.
It is recommended to use polarised sirens or bells fitted with a suppressor.
Water Alarm Output [B08,B09]
Terminal B08 is a 12v supply fused at F1A, sharing a common fuse (F6) together with the Buzzer Output. Terminal
B09 is an open-collector npn transistor output, switching from 12v to 0v on detection of a Water Alarm condition.
This output is suitable for driving a siren, bell or sounders.
Alternatively, it is possible to activate a Solenoid Water Valve to disconnect the water supply. Note that in most
cases a 230VAC isolating relay is required to operate the Solenoid Valve. It is recommended to fit a suppressor
diode across the relay coil to prevent damage due to high voltage transients, as shown in Figure 3. Some relays
are supplied with a suppressor fitted internally.
IMPORTANT: DO NOT CONNECT 230VAC DIRECTLY TO THE NOBY-65 TERMINALS.
Internal Warning Buzzer Output [B10, B11]
This output is provided at terminals B10 & B11 for audible indication of warning and fault conditions. Terminal B10
is a 12v supply fused at F1A, sharing a common fuse (F6) together with the Water Alarm Output. Terminal B11 is
an open-collector npn transistor output, switching from 12v to 0v.
The Noby-65 emits the following Buzzer tones:
It is recommended that the Internal Warning Buzzer (or piezo sounder) can be heard outside the Final Exit Door,
so that the keyholder can hear the Exit-Time finish and be confident that the Noby-65 is fully armed.
Following an alarm condition the Buzzer will continue to sound until the keyswitch is turned to OFF.
Duress / Panic Signal [B12]
A positive going 12V/10mA signal output (B12), which latches on receipt of a Duress or Panic alarm condition. This
output is cleared by performing a System Reset. This signal is provided to trigger Remote Signalling Equipment.
PIR Memory SW+ Signal [B13]
A positive going 12V/10mA signal output B13, switching to 12V when the Noby-65 is either Full-Set or Part-Set.
This signal can be used to control the latching LED function of PIR detectors connected to Zone-1 or Zone-2.
To reset a latched PIR detector:
The SW+ signal can also trigger Remote Signalling Equipment to transmit an Open/Close signal to a central
monitoring station.
Note: Some PIR detectors require a 10K pull-down resistor to be connected from terminal B13 to 0V.
The Noby-65 has an internal keyswitch fitted as standard, supplied with 4 keys. The switch has the following
positions:
i) OFF: All Intruder circuits are disarmed. Other 24-hour circuits remain active.
ii) FULL-SET: All Intruder circuits are armed. Noby-65 is Full-Set after the Exit Time.
iii) PART-SET: Noby-65 is Part-Set after the Exit Time, with Zone-2 isolated.
External Keyswitch Connections[B14,B15,B16,B17]
The Noby-65 can be operated remotely by connecting an external keyswitch to terminals B15-B17 as shown in
Figure 3. Note that switching terminal B15 to 0v causes the Noby-65 to Full-Set, whilst switching terminal B17 to
0v causes the Noby-65 to Part-Set. Terminal B16 is the 0v connection. Terminals B14 and B15 must be linked
together for correct operation of the internal keyswitch.
An attractive alternative to a mechanical keyswitch is the Nobycode NC-02 Remote Keypad (Figure 4). The NC02 is specifically designed to control the Full-Set, Part-Set and System Reset functions of the Noby-65. The NC-02
keypad also has 2 LEDs to remotely indicate the ON/OFF status and the Alarm/Fault status of the Noby-65.
For additional security it is recommended to remove the two EOL resistors from the Noby-65 terminals and reconnect them in the remote keyswitch housing, such that any break in the cable will force the Noby-65 to either
Full-Set or Part-Set the intruder system.
For high security installations it is also recommended to route the Sabotage circuit though the cable and connect
through any lid microswitches.
REMOTE SIGNALLING EQUIPMENT (AUTO-DIALLER)
The Noby-65 cabinet can accomodate an Auto-Dialler underneath the main circuit board assembly. Figure 1
shows a typical Auto-Dialler connection diagram. The channel numbers may differ according to the signal priorities
demanded by the remote central station. Also take care to ensure that the Water Alarm channel is programmed to
be a negative going input signal.
