OTHER INPUTS

TAMPER - A 24Hr tamper circuit is available for monitoring system tampers. This Tamper circuit is programmable as
either normally closed loop or 2k2 EOL supervision (the default is 2K2 EOL Supervision). Any Tamper alarms on this
input are mapped to alarm outputs in the same manner as for detection zones 1-16. Using Dual-End-of-Line resistors
(Refer to Zone Type 15 on Page 6) the Tamper input can also provide two key-switches. The Low key-switch (4k7
resistor) will be Key-switch 1 while the High key-switch (8k2 resistor) will be Key-switch 2.
In addition to the Zone & Tamper inputs, you will find the following additional inputs on the control PCB;
AC - Connect the 17VAC yellow wires (no polarity) from the transformer to the terminals marked AC on the PCB. The
panel includes a mains transformer rated at 1.4 amps at 17 VAC.
EARTH - Connect the mains earth to the appropriate terminal on the mains terminal block in the control box cabinet.
Also connect a lead from this earth point to the terminal marked with the Earth symbol (next to AC terminals) on the
panel PCB.
BATTERY - Connect a sealed lead acid rechargeable 12VDC battery to the terminals labelled red and black on the
control panel being careful to observe the correct polarity. The minimum recommended battery capacity is 7 amp
hours. Battery charge current at these terminals is limited to 300mA maximum. The battery connection is protected
against short circuits by a thermal fuse (F1). The panel performs a dynamic load test on the battery every 15 seconds
and if it fails the test at any time it will flash the Battery LED.
LINE IN - These terminals are used to connect the panel to the incoming telephone line. The dialler uses this line for
reporting alarm events. An ADSL filter will be required before the Line In terminals if ADSL is present in the building.
LINE OUT - These terminals are used to connect telephones and other communication equipment to the incoming
phone line via the panel dialler circuit. The telephone line is passed through the controller to ensure that the line is
available to the controller when it is required.

OUTPUTS

12 VOLT OUTPUTS - There are three 12VDC outputs on the panel PCB. These 12 volt outputs are regulated and Thermal
fuse protected against short circuits. The accessory outputs are marked 12V and 0V, while the keypad buss 12V supply is
labelled "POS" & "NEG". The 12V outputs are supplied by thermal fuses F2 & F3. The recommended maximum total load
that should be drawn from all of the 12V outputs is 1A.
OUTPUTS 1 & 2 - These fully programmable, high current, open drain (high-going-low) type FET outputs capable of
switching up to 1.5A @ 12VDC. These 2 outputs are normally set as switched outputs, providing power for 12V sirens
or piezos. If required, these outputs can be programmed to be siren outputs designed to drive an 8 ohm 10 watt horn
speaker on each output (see P37E option 1). Also if a horn speaker is connected to Output #1 you may select (Refer to
P175E 7E program address) the listen-in feature to this output as well so that the dialling sequence can be heard at the
speaker.
OUTPUT 3&4 - These are low current, open collector (high-going-low) type transistor outputs capable of switching up
to 400mA. Like Outputs 1 & 2 they are fully programmable.
NOTE: - Connecting devices that draw current in excess of 400mA to outputs 3 or 4 will damage the output.
OUTPUT 4 Relay - This is a relay output (rated 1A@30VDC) that works in parallel with the transistor output with single
pole changeover contacts. If required, the Common (C) contact of the relay can be connected to either 12V or 0V via
Link 1. Like Outputs 1 & 2 it is fully programmable.
KEYPAD PORT - The terminals marked POS, NEG, CLOCK, & DATA make up the communications port which the keypads
and other intelligent field devices use to talk to the controller. The terminals are connected to corresponding terminals
on the remote devices. The "lin" terminal is only used by the keypads and utilises a fifth wire to provide a communicator
"listen-in" facility. This feature is particularly useful when servicing monitoring faults. The keypad 12V supply (POS,NEG)
is protected by fuse F3.
EXPANSION PORT - The expansion port allows connection of the RS232 serial board, 90 second Voice Board, DTMF
Board or EEPROM data transfer board (DTU). The serial board allows direct connection of a PC running the Upload/
Download software. The 90 second voice board allows voice messages to be programmed for monitoring purposes. The
Voice & DTMF boards allow Touchtone Code remote control via a telephone. The DTU allows for program "Cloning"
from one panel to another.
