TS700 LEC Installation

The TS700 LEC (Local Expansion Card) is

connected to the “Remote Network” and provides

two additional programmable detection circuits

and a programmable output. The “Remote

Network” may have up to three LECs connected,

as the system will always require at least one

remote keypad.

Always ensure that all power (mains

and battery) is removed before

making any connections to the LEC.

1. Remove the cover from the base and carefully

remove the PCB.

2. If the LEC is being fitted inside the control panel

you may remove the LEC PCB from its base

and secure it to base of the control panel using

self adhesive feet. If required, the tamper

switch may also be disabled by fitting the

jumper link across JP2, see Figure 12.

3. If the LEC is being fitted outside the control

panel, hold the base in position and mark the

two securing holes. Drill and plug the wall, then

pass all cables into the base via the cable

entry points. Secure the base to the wall using

the appropriate fixing screws.

4. Connect “Remote Network” cables and

detection circuit cables to the appropriate

terminals, see Figure 12.

5. Set the I/D selector jumper link to the required

position:

NULL N/A N/A N/A

No two LECs or remote keypads should

have the same I/D.

DO NOT set the I/D selector to the “NULL”

position.

6. Finally clip the LEC cover onto the base being

careful not to trap any cables or to obstruct the

tamper switch.

Wiring Detection Circuits

All detection circuits may be wired as "End Of Line"

(EOL) or "Double Pole" (DP). Both methods can be

used on the same equipment.

Double Pole

The DP method requires the following:

The detector alarm and tamper contacts are

connected to the zone and tamper terminals

respectively.

The combined alarm and tamper loop

resistance must be less than 100 Ohms.

The maximum number of detection devices

allowed in a circuit is ten.

Normally open devices such as pressure pads

and exit terminator buttons are connected

between the zone and tamper terminals.

If the detection circuit is not used links can be

fitted across the zone and tamper loops or

programmed as Not Used.
