3. With the ID loop still disconnected from the

control panel, use a DVM to measure the

resistance between the following cores and

terminals:

(a) ID + core and 0V terminal.

(b) ID + core and +12V terminal.

(c) ID + core and Mains earth terminal.

(d) ID - core and 0V terminal.

(e) ID - core and +12V terminal.

(f) ID - core and Mains earth terminal.

In all cases the DVM should indicate an open

circuit, any other reading could indicate a

short circuit or wiring fault and must be

investigated.

4.

At the control panel, twist the two cores of the

ID loop together so that the ID loop is shorted.

5. At each end of the ID loop (points A, B and C in

our example shown in the figure below)

measure the resistance between the two

cores of the ID loop (normally theses are the

yellow and blue cores). See the table of page

8. A reading greater than 2K Ohms is usually

caused by an open circuit.

6. Re-connect the ID Loop to the control panel.

When the system is powered up use the “SLOW

SCAN” feature to check voltage levels at each

device, see page 37.

Initial Power-Up

To power the system for the first time:

1. Place a small screwdriver blade between the

pins on the control panel PCB, marked

“FACTORY RESET”. This will ensure the factory

default parameters are set, see page 24.

2. Switch on the 240V mains supply and remove

the screwdriver blade.

3. Check that the power LED on the control panel

PCB is illuminated.

4. Check that the LED remote keypads display

“LT” (Panel Lid tamper) and LCD remote

keypads display “Panel Lid tamper”. The

remote keypad sounders and extension

loudspeakers will operate.

5. Enter the engineers passcode (default 1234) to

silence the sounders.

6. Connect the standby battery.

Power-Up Checks

When the initial power-up checks have been

completed, check the following:

1. Switch off the 240V mains supply and measure

the DC voltage at each remote keypad and

ensure the voltage is greater than 11V whilst

the system is powered from its standby battery.

2. Switch on the 240V mains supply and measure

the DC voltage between the mains earth

connection and AUX. +12V. Then measure the

DC voltage between the mains earth

connection and AUX. 0V. In both cases the

measurement should be 1V or less. If the

voltage is greater than 1V, the system has an

“Earth Fault” and all cables should be checked

for isolation to Earth

3. Using a voltmeter measure the DC voltage

across the control panel PCB test points (V) and

calculate the system current consumption

(see page 11). Ensure that the reading is not

greater than 1.0A (1.5A for TS690ID).

4. Repeat test (3) with the system in an alarm

condition and ensure that the reading is not

greater than 1.0A (1.5A for TS690ID).
