T-GEN 50
The T-GEN 50 is permanently powered, requiring a supervised Alarm- signal from the FIP
rather than switched power. The BELLS- terminal can be used for this, refer Figure 5.5.7.
Alternatively, an Ancil relay on the MAF, or an 8RM relay can be used as per Sections 3.4
and 3.5 of the T-GEN Installation Instructions, LT0186.
Note that a 2k5 ELD (3k3 and 10k 1% in parallel) must be used for the BELLS relay, when
connecting to the ALM- input on T-GEN. Configure the T-GEN to NOT supervise its ALM-
input (SW4 off).
Alternatively, an open collector output could be used, but the T-GEN will need to supervise
its ALM input and be fault supervised via an unused F3200 circuit input.
MICROVAC AND QE90
The Anc 3/Bells output can be used to activate a Microvac/QE90 and to supervise the link
for a fault condition. A 24V relay (e.g. PA0730 General Purpose Relay Bd) is required to be
mounted within the Microvac/QE90, and the wiring as shown in Fig 5.5.4.
Alternatively the Anc 3/Bells output can be made voltage-free (remove Lks 2, 3, 4 on the
MAF) and a spare 8 Zone Input can be used to supervise the Microvac/QE90. This
arrangement, shown in Fig 5.5.5, does away with the relay, but requires a 4-wire connection
and one spare input. The input should be programmed as a status-only zone and the fault
state included in the logic equation to generate a Warning System fault. E.g. for zone 16
WSF = Z16F.
A high level link can be achieved between the F3200 and QE90 using the RZDU
communications output. This is only suitable for when the F3200 and QE90 are co-located,
as there is no duplication of the cable. Details for this wiring are contained in the QE90
Installation and Commissioning Manual LT0088. In addition, the QE90 needs to be
supervised for a fault condition. This can be done as shown in Fig 5.5.5 using a spare zone
input or as in 5.5.4 using the Ancil 3/Bells output supervision.
