Using T-GEN 50 with 4100ES-S1
AS 1670.1 requires fire alarm warning systems to produce sounds complying with
ISO 8201. One way of meeting this requirement in a 4100ES system is to use a T-
GEN 50 tone generator, which is capable of driving up to 50W of load on a 100V speaker
line.
The recommended version of the T-GEN 50 for use in 4100ES-S1 is available as part
4100-0766K (see PID information in Chapter 1). This consists of a T-GEN 50 mounted
on a metal bracket which is mounted into the expansion bay in the same way as a legacy
4100 motherboard. This part code includes the necessary mounting hardware.
The best place to mount this bracket is in the right-most free slot in the expansion bay,
next to the mains socket bracket. The bracket should be installed with the T-GEN 50
facing to the left - this is “upside down” compared to some other uses of this bracket.
Note also that the heat sink of the T-GEN 50 intrudes slightly into the space above the
next slot to the left. This will probably clash with other motherboards or modules and
make this slot unusable.
The T-GEN 50 must be continuously powered from nominal 24VDC, i.e., not just during
Alarm conditions, so that it can supervise the 100V speaker line.
The recommended method is to power the T-GEN 50 from the AUX POWER terminals
of the SPS power supply. This output is rated at 2A, which is just sufficient to drive one
fully loaded T-GEN 50. However, this leaves no reserve for any other equipment to be
powered from these terminals, e.g., a brigade signalling device.
If 24V DC is required for other ancillary devices as well, this can be supplied from one of
the NAC outputs via the Fused Distribution Board PA0915. The wiring for this is shown
in Figure 5-4.
