24V Alert & Evacuate Tone Generator
INSTALLATION AND OPERATING INSTRUCTIONS
The VIGILANT T-GEN 50 is a self-contained AS 2220 and ISO 8201 Alert and Evacuate tone generator, with speaker
line supervision and speech. It has been designed to connect directly to fire alarm panels, but may be connected to other
suitable digitised equipment.
T-GEN 50 is available in 2 versions (see page 8 for a full list of available items and accessories):
PA0766 Tones, fault supervision and speech. Contains (SF0341) –Speech IC with 4 pre-recorded messages
that are inserted into the Alert and Evacuate tones. A microphone input is also provided for
emergency public address and for recording messages different to the standard messages supplied.
A suitable microphone is Part Number ME0290.
PA0886 Same as PA0766 except fitted with SF0309 software and SF0342 speech IC in which the alert
message is a recorded bell sound. Alert and evacuate tones may separately be disabled so only the
recorded messages are played. DIP switches 5-8 select different functions.

OPERATION
Operation of T-GEN is controlled by the Auto/Isol/Evac (AIE-) input. In the “Auto” position the Alarm input (ALM-) is
enabled. In the “Isol” (Isolate) position the Alarm input is disabled and any latched fault or alarm conditions are reset. In
the “Evac” position the Evacuate tone is generated.
In Auto mode activation of the Alarm input starts a six stage rising amplitude Alert tone. This continues until one of the
following occurs:
- the Alarm input returns to normal (Alarm input in non-latching mode), or
- the AIE- input is changed to Isol, or
- the AIE- input is changed to Evac, or
- the Alert to Evacuate change-over time is reached.
If the Alert to Evacuate change-over time is set to 0 sec, then no Alert tone is generated and the Evacuate tone is
generated immediately. If the change-over time is set to Alert only, no Evacuate tone is generated and must be initiated

LT0186 Issue 2.80 27 July 2012 Page 2 of 10
manually. On the PA0766 model Alert and Evacuate voice messages are automatically inserted in the Alert and Evac
tone sequences respectively. Messages shorter than 0.5 seconds are not inserted.
Generally the AIE- is left open (Auto) and operation of the T-GEN is controlled via the ALM- input from the fire panel. A
switch for the Isolate and Evacuation positions should be fitted only when there is no other warning system isolation
facility (e.g., on older AS1603.4 panels). For this arrangement, consideration should be given to indicating the isolate
position via a hard-wired yellow LED or fault condition on the fire panel (see Section 3.1).
If the 100V line is over-loaded (e.g. short circuit), T-GEN will shut down its amplifier output until the fault is removed.
A test mode is provided for testing the 100V line and speakers. To activate this put T-GEN in Auto and fit the Test Link
(LK4). T-GEN will produce a short 500Hz tone burst every 4 seconds at low volume (-30dB). (Excludes Wail and Hee
Haw for PA0766 and AS2220 for PA0886).
PA0886 may be used for voice only applications (disable tone generation). Operating the ALM- input will activate the
alert message, operating the A/I/E- input will activate the evacuate message.
Slave Mode
In slave mode T-GEN does not produce its own tones but connects to a Master T-GEN via the SIG terminals. When
connecting T-GENs together there must be only one Master T-GEN. Note that only the Master generates the tones and
background music, and is connected to the panel Alarm output and Auto/Isol/Evac switch. All slaves (max 20) and the
Master T-GEN must be co-located and share the same 0V.
Fault Monitoring
If Alarm input fault supervision is enabled, then an open circuit on the ALM- input will cause a fault condition. Detection
of an open or short circuit on the 100V line output (Master or Slave mode) or the SIG input (Slave mode only) will also
cause a fault condition. A fault condition will turn on the Fault LED and depending on Link 7 activate the Fault Relay or
the DEF- output. Note that the 100V line is not supervised for the first 60 seconds after power up to allow the monitoring
capacitors to charge up.
Note that the fault output is disabled when the T-GEN is in “Isol”.
Public Address
The operator may use the PA microphone (part number ME0290) for emergency public address. This is activated when
the microphone’s PTT button is pressed while the A/I/E switch is in the Auto or Evac position. Public address overrides
Alert and Evac tones.
A remote microphone can be connected to the T-GEN for general paging by using the PA0688 microphone preamp.
Details are contained in the PA0688 Microphone Pre-Amplifier Module User Manual (LT0371).
Evacuation Messages
The four messages are defined as Msg1, Msg2, Alert and ISO8201 keywords. Refer to the table for the actual pre-
recorded phrases. PA0766 will play the alert message during alert, Msg1 (or Msg1 + Msg2 if recording is longer than 4
seconds) during AS2220 or ISO8201 Evac if SW8 is off, Msg2 during AS2220 if SW8 is on, and just the ISO8201
keywords during ISO8201 if SW8 is on.
PA0886 will play a bell sound instead of the Alert tone and alert message. It will play Msg1 (or Msg1 + Msg2 if recording
is longer than 4 seconds) during AS2220 Evac (SW6 and SW8 OFF) if LK4 is OFF and just Msg2 if LK4 is ON (TEST
Mode is not available in AS2220 Mode). In ISO8201, Msg1 (or Msg1 + Msg2 if recording is longer than 4 seconds) will
be played back after the second keyword. If no Evac message is present, PA0886 will play ISO8201 with keywords only.
Recording Messages
The T-GEN supports 2 recordable messages, Alert and Evac. Alert can be up to 4 seconds duration. Evac consists of
two factory-programmed messages (Msg1 and Msg2) that can be up to 7.2 seconds in total length. The Alert and Evac
messages can be re-recorded using an ME0290 PA microphone.
To record a message use the following steps (when T-GEN is not in alarm or evacuate or test mode):
1. Fit link LK3 - REC EN on the PCB. This enables the recording and playback of messages.
2. Select the message to be recorded (played) using switch 2 - T1 as follows:
T1 Off - Evac message T1 On - Alert message
3. Press the microphone button to start recording. Recording will continue until either the button is released or the
maximum message length has been reached. (See NOTE).
4. The recorded message can be played back using the Play button. Note that if the A/I/E switch is not in the
Isolate position the played back message will be broadcast over the speaker system. Recording is not
broadcast.
5. When recording has been completed, re-set T1 to its original position and remove Link LK3 to disable the
record function.
NOTE: Messages less than 0.5 seconds will not be broadcast (this can be used to delete an unwanted message). Note
that if Evac Msg1 is replaced with a message of more than 4 seconds duration, Evac Msg2 will also be
overwritten.

INSTALLATION INSTRUCTIONS
1. MOUNTING
T-GEN has the same mounting holes as an MX4428 responder or F3200 card so it can be mounted in an MX1, MX4428
or F3200 cabinet using the mounting holes provided, or in an F3200 card frame. The 5 PCB standoffs required for
mounting T-GEN are supplied, and require 6mm diameter mounting holes on a 90 x 90mm pattern. Note that T-GEN
must be earthed (refer 3.7).
The T-GEN heatsink is at +27V and under full load may reach a high temperature, so all wiring must be kept clear of the
heat sink and air should be able to flow freely around it. No part of the cabinet, card frame or wiring must touch the heat
sink.
For information regarding legacy NZ panels, please refer to LT0233.
The 3U 19” rack mounting version (FP0698) should be fitted to the 19” rack cabinet using the included mounting
hardware. If the Auto/Isolate/Evacuate switch is required (not recommended for fire panels complying with AS 4428.1 or
AS 7240.2) remove the plug and fit the keyswitch supplied loose. Wiring is detailed in Section 3.1.
This is a Class A product. In a domestic environment this product may cause radio interference, in
which
case the user may be required to take adequate measures.
2. SPEAKER WIRING
2.1 100V SPEAKER LINE WIRING
The T-GEN has 100V line supervision, and therefore requires a decoupling capacitor at each speaker transformer and a
56k resistor ELD on the end of the line. If wiring on two branches then two 100k ELDs are used, one on each branch.
The capacitors must be bipolar, and their value should be 1 - 5uF per Watt of their speaker’s load (see below). See
Figure 2.1 for wiring details.
Speaker Load
0.33W - 0.5W
1W - 5W
10W - 20W
40W
Capacitor
1uF
10uF
47uF
100uF
It is possible to use a higher value capacitor on all speakers, however if there are a large number of speakers on the line
then T-GEN may indicate a fault after power up. This will clear after a few minutes once the supervision voltage on the
line has stabilised. The capacitor’s voltage rating must be at least 10V.
Note
1. Capacitor 10V bipolar. Value 1-5 uF per Watt of speaker load.

Note:
100V a.c. audio line wiring is defined as LV Telecommunications circuits and is subject to the Australian
Standard AS/ACIF S009:2006.
Ensure that this wiring is appropriately separated and insulated from LV power wiring, ELV and other customer
cabling such as detection and control circuits.
100V wirin
g is required to be double insulated.
A 100V warning label is provided which should be placed next to the T-GEN 50’s 100V line terminals.
2.2 SPEAKER / HEADPHONE OUTPUT
The T-GEN has an optional 8:speaker / headphone output that can be used to output recorded messages only, when
the play button is activated. This speaker output is not disabled when the A/I/E switch is in the Isolate position. The
speaker is connected to terminals J2 and J3 on the PCB.

LT0186 Issue 2.80 27 July 2012 Page 5 of 10
3 INPUT WIRING DETAILS
3.1 Auto/Isolate/Evac Switch.
The use of the Auto/Isolate/Evac switch is not recommended in fire panels compliant with AS 4428.1 or AS 7240.2, as
the isolate facility on this switch is a duplication of the AS 4428 Warning System Isolate or AS 7240 Alarm Devices
Disable function already provided on these panels, and there is no indication of the Isolate position.
However, the switch may be useful with older AS1603.4 fire panels, in which case the Isolate position should be
indicated.
An LED (and resistor) could be wired to turn on in the Isolate position via a spare switch contact (Figure B), or a fault
could be generated on the fire panel when the switch is in the Isolate position. For example, wire the ELD 0V connection
through the Auto and Evacuate switch contacts so a fault is generated in the Isolate position (Figure C).
Alternatively, if the Isolate position is to be disabled (but the Auto and Evacuate positions retained) remove the 10k
resistor from the Isolate switch and blank off the word “Isolate” on the label.

3.2 Background Music/Remote Paging
An external audio source can be connected to the T-GEN MUSIC input, J9, for background music, external paging, etc.
This source must have an isolated output, otherwise an audio isolating transformer, e.g. the ALIM9706 (part number
PA0646), must be used. Refer to LT0372 for the ALIM wiring arrangement.
A background music loom adapter consisting of a 2 way plug with red (SIG) and black (GND) wires is supplied with the
T-GEN.
Remote paging (non-emergency) can be achieved by using the PA0688 microphone preamp board. Refer to LT0371 for
details.
3.3 Microphone
An emergency PA microphone (part number ME0290) can be connected to J1 on the T-GEN.
For a remote emergency PA microphone, refer to LT0371 for using a PA0688 microphone preamp.

3.6 Connecting T-GEN using the DEF- Output
The following wiring is recommended for when the T-GEN is mounted in or adjacent to a fire panel that supports the
DEF- signal. Using the DEF- output disables the T-GEN fault relay, and therefore the quiescent current is 17mA lower
per T-GEN compared with using the fault relay. But the DEF- line is not supervised for open circuit. Note that link Lk7 on
the T-GEN(s) must be fitted in the DEF- position.
The power supply for the T-GEN must be supplied from a monitored 24V supply.

3.7 Earth Connection
The T-GEN must be connected to the cabinet EARTH using either the EARTH terminal on the T-GEN PCB (located
beside the 100V Line Output) or by using a metal standoff on the bottom left hand mounting hole (an M4 washer and
nut are supplied).
3.8 Power Connection
WARNING: Each T-GEN 50 draws approximately 10A for 20 ms when first powered up. Any fuse between the T-GEN
50 and its power supply must be a slow blow type rated 3A minimum (per T-GEN 50). Any switch contact
used to supply power to a T-GEN 50 must also be rated at 10A minimum (per T-GEN 50).
The T-GEN 50 presents a significant capacitance (6600μF) on its power terminals, hence the high inrush current. This
capacitance can also invalidate the battery connection tests (that lower the charger voltage to see if the battery is still
present) on some power supplies (e.g. 1948 PSU) if the T-GEN 50 is the only device powered by the PSU. In this case
it may be necessary to add a power resistor to the PSU output to provide extra standing load. For the 1948 24V PSU a
820 ohm 5W resistor is typically required. Note the 33mA this resistor draws needs to be included in any battery
capacity calculations.

PA0766 PCB Assy,1955-1-3,T-GEN,Tones,Flt Mon, PA Speech
Standard model of T-GEN with SF0341 speech IC pre-recorded messages for Australia and New Zealand.
PA0886 PCB Assy, 1955-1-3, T-GEN, NZ Bells and Speech, Flt Mon, PA
Similar to PA0766, but has SF0342 speech IC with a bell sound recorded instead of the alert message and has different
software to support playing the messages only (no tones). Hee-Haw tone is not supported, and the Wail and RH3 tones
cannot have the Evacuate message inserted.
FP0698 FP, T-GEN, 3U Rack Mtg Panel, C/W PCB & Mic
A 3U 19” rack mounting module complete with a PA0766 T-GEN 50 mounted on the back of it. A microphone and front
panel label are supplied fitted to provide a complete functional unit. A loom for power, control and monitoring is factory
fitted. The loom is connectorised for direct use with MX1. The connector can be removed and the loom wired into other
panels if required. An Auto/Isolate/Evacuate keyswitch is included loose for fitting if required. Wiring to the 100V
speaker line is also required to make it operational.
ME0289 Mech Assy, 1955-16, T-GEN, 1U Rack Mtg, A/I/E Control Panel
A 1U 19” rack mounting module that has a 3 way rotary switch and Auto/Isolate/ Evacuate label on it, wired so that it can
be connected to T-GEN. No T-GEN is included.
ME0290 Mech Assy, 1955-3, T-GEN/MVAC Dynamic Microphone
ME0490 Mech Assy, 1955-44, T-GEN 50, Dynamic Microphone
A noise-cancelling dynamic microphone suitable for plugging onto the T-GEN to provide emergency PA or for field
recording of the digitised speech message(s). ME0290 has a 1m coiled cord. ME0490 has a 1m extension to this coiled
cord, suitable for internal routing in the cabinet, if required.
ME0291 Mech Assy, 1955-24, T-GEN A/I/E Switch Kit
A small metal bracket containing a 3 position rotary switch, labelled and wired for connection to the T-GEN A/I/E- input.
This allows control of T-GEN’s operation through selection of the Auto, Isolate and Evacuate positions. The bracket can
be mounted in most fire alarm panels.
ME0292 Mech Assy, 1955-25, T-GEN Empty Box, Keyed 003
A 240W x 295H x 85D, cream wrinkle coloured, locked, metal box suitable for mounting the T-GEN (not included) inside.
A standalone tone generator and PA announcement system can be constructed by using the T-GEN mounted in a
cabinet (e.g., ME0292), together with the ME0291 Auto/Isolate/Evacuate switch, and the ME0290 microphone. A
suitable power supply is also required, (e.g. Series 1948 24V 2A (FP0766) and 2 x 6.5Ah hour batteries - this is the
same size as the T-GEN box).
