Twinflex V3 Control Panel Engineering and Commissioning Manual

Mode 3 – Class Change
On application of a 0V trigger, the sounders will operate until the trigger condition is removed, but
the control panel will show no indication, and neither the ‘Fire Relay’ nor the ‘Remote Alarm
Output’ will operate.
Mode 4 – Remote Alarm
On application of a 0V trigger, the sounders will operate, the control panel will show ‘Common
Fire’, ‘Remote Alarm Input’ and ‘Remote Alarm Output’ indication, and the ‘Fire Relay’ and the
‘Remote Alarm Output’ will change state. This will reset when the trigger condition is removed.
Internal Speaker: INT SPEAKER +/-
This feature is not currently in use.
Auxiliary Power: Aux 24V O/P +, Aux 24V O/P
Nominal between 21 and 27V
800mA of auxiliary 24V DC power is available here. It is recommended that additional Power
Supply Units be installed to provide power for additional loads.
Power Supply: DC, DC, EARTH
The DC input is connected to the red and black leads coming from the switch mode power supply
mounted within the back box, and is the primary power supply for the system.
Note: Previously the control panel used a 24V AC input, connected to a transformer mounted
within the back box. Ensure that the correct type of power supply is utilised.
Repeater Outputs: Z1, Z2, Z3, Z4, A = FLT O/P, B = RESET O/P
The repeater output will change to 0V when the relevant state is present, ie, the ‘Z1’ terminal will
become 0V when zone one is in the fire state. An Led or low current relay may be operated if
connected between this terminal and auxiliary 24V positive. Any relays must be dioded. See the
section on relays for further information.
Repeater Inputs: D = SILENCE, E = RESET, F = EVAUATE
These inputs require that a switched 0V trigger is applied in order for the relevant action to take
place as follows;
F = EVAC - Evacuate Input
On application of the 0V trigger input the sounders will operate, the control panel will show
‘Common Fire’ and ‘Remote Alarm Output’ indication, and the ‘Fire Relay’ and the ‘Remote Alarm
Output’ will change state. This will latch in place and the control panel must be reset to clear the
event.
D = SIL – Silence Input
On application of the 0V trigger input the alarm sounders will stop if they were operating.
E = RST - Reset Input
On application of the 0V trigger input the system will reset.
