INSTALLATION AND MAINTENANCE INSTRUCTIONS
802-0002 Twinflex Input Module (Detector)
802-0003 Twinflex Input Module (Call Point)
26-0352 Issue 6
General Description
The Twinflex Input module is available to enable the Twinflex system to receive a fire input signal from the zone
circuit. This device is compatible with the Twinflex range of Fire Alarm equipment as an auxiliary input unit. The unit
consists of a boxed module which may be mounted within the unit to be monitored. Upon activation the module
generates a ‘DETECTOR ALARM’ or ‘MANUAL CALL POINT ALARM’ at the control panel depending on
speification.
Device Installation
All wiring must be installed in compliance with the recommendations laid out by BS5839 Pt1 : 2002 as well as any
special recommendations documented in the control panel installation manual. The cabling used should be of a 2-
core 1.5mm
2
screened, fire resistant type (e.g. MICC or FP200 equivalent), and is to be wired in the form of a
screened 2-core radial circuit (with no spurs) from the control panel, terminating at the last (“End of Line”) device.
Installation 1
st
Fix
Fix the interface (surface/boxed single gang) in a suitable position remembering to allow enough space for the
correct termination of the appropriate cables. The interface PCB must be mounted within 15cm of the contacts to
be monitored.
Installation 2
nd
Fix
Once all testing has been carried out on the cabling, and ‘continuity & integrity’ of the zone pair has been proven,
the interface unit may be connected and commissioned. Remember to set the end of line (EOL) switch to the on
position if the unit is the last device on the circuit. It is important to note also, that this input is a ‘latching fire input’,
and is not fault monitored.

No screen connection is allowed for within the device. Incoming and outgoing cable screens must therefore be
connected through using a suitable connector. It is important to maintain the screen continuity in order to protect
against data corruption from interference.

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 screen connection at each Input Module is via a separate terminal
connector (not inclu ded) and is not on the circuit board.
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).
