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 (6600

μ

F) 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.
