Terminal Description
EARTH Connect this terminal to the green wire on the TF008 Plug Pack that is internally connected
to mains earth. Because extensive lightning protection is built into the control panel, this
terminal must be connected correctly to take advantage of this protection.
18 VAC These two terminals are plug-on type, and are the termination point for the TF008 Plug Pack.
To ensure correct operation, the voltage of the plug pack must be 18 VAC to 22 VAC at 1.3
A (minimum).
+BATTERY
–BATTERY
The +BATTERY terminal connects to the red positive terminal of the battery and the –
BATTERY terminal connects to the black negative terminal of the battery. The battery should
be a 12 VDC sealed lead-acid rechargeable type with a capacity from 1.2 Ah to 6.5 Ah. The
battery is protected by a 2.5 A PTC.
The charging globe situated above the 2.5 A PTC lights until the battery is 100% charged.
GND
+12V
CLK
DATA
This group of terminals provides the connection points for the system codepads. Connect all
system codepads in parallel back to these terminals. The only factor restricting the number of
codepads you can connect is the available power and its distribution. Because each
codepad has a maximum power requirement of 60 mA with all indicators lit, consider this in
calculating your available continuous power. The total continuous external load cannot
exceed 1 A.
STR
OUT 1
+COM
These terminals are the output terminals. You can configure the outputs to any combination
of the functions available through the system programming options. You can use them for a
variety of functions with considerable flexibility. All outputs have a common +12 VDC terminal
and each output can sink up to 400 mA. By default, Output 1 operates a horn speaker.
This group of terminals is protected by the solid-state Integrated Protection System (IPS). IPS
tolerates abuse or incorrect wiring. Each open collector output does not use any current, but
can provide up to 400 mA.
COMM
N/O
These relay contacts are fully programmable similar to the strobe and Output 1. By default,
they are alarm output (Sirens Running – Output Event Type 1,15).
The NO contact is the connection point for the positive side of a DC siren, such as a piezo
screamer. The negative side of the DC siren connects to the GND terminal. The PCB
provides a link (JP2) to connect the COM terminal to either GND or +12 V. Connect this link
to +12 V as shown in Figure 11 on page 81. The relay is rated at 1 A at 30 VDC.
+12V
Z4
Z3
Use these terminals for Zones 3 and 4. The common terminal is +12V. Connect all normally-
closed contacts in series with the EOL resistor and connect all normally-open contacts in
parallel with the EOL resistor. The function of the zones and their response times are
configured using the system programming options. If split EOL is programmed, 24-Hour
Zones or Keyswitch Zones connected in parallel to Zones 3 and 4 act as Zones 7 and 8.
+12V
GND
Use these two terminals to provide power to detectors and other equipment. They are
protected by the 1 A PTC.
Z2
Z1
+12V
Use these terminals for Zones 1 and 2. The common terminal is +12V. Connect all normally-
closed contacts in series with the EOL resistor and connect all normally-open contacts in
parallel with the EOL resistor. The function of the zones and their response times are
configured using the system programming options. If split EOL is programmed, 24-Hour
Zones or Keyswitch Zones connected in parallel to Zones 1 and 2 act as Zones 5 and 6.
