Remember that the device at the end of the line must have its EOL signal activated using the
relevant EOL switch. Do not use a resistor or capacitor (or another manufacturer’s End of Line
device) as the end of line, as this may prevent correct operation of the zone.

Note: the scre en connection at each Input Module i s via a separate terminal
connector (not inclu ded) an d is not on the circuit b oard.
Twinflex Input Modules can be mixed on the same zone as other types of Twinflex device (eg. Twinflex Multipoint
Detectors). The above diagram shows how to make the zone positive, zone negative and screen connections
between the control panel and Twinflex Input Modules. Refer to the instruction leaflets supplied with other Twinflex
devices for their equivalent wiring/terminal labelling details.
Please note that the screen connections at each Input Module should only be connected to the zone cable screen
and NOT to the building earth. The cable screen is connected to earth at the panel end only, via the zone “SCRN”
terminal (or EARTH terminal on the Twinflex V3 2/4/8 Zone panels).
Testing
The unit may be tested by applying a short-circuit between the two alarm terminals, but it is better to operate the
device which controls the contacts to which it is connected. This will cause the control panel to enter the fire state.
When the cause for the alarm is removed the control panel may be silenced and reset.
DIL Switch Settings
The last device on the circuit must have the EOL signal enabled
(switch number 1 in the ‘ON’ position).
