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.

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

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 wiring 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.
