1024 REV 1.0 QUAD LEM

1024 REV 1.0 QUAD LEM (Q-LEM)

The Model 1024 Rev 1.0 Quad Line Encoder Module (Q-LEM) features four input-loop

connections and a tamper switch that can either be active or be shunted by switch number 8 on

the DIL switch. The Q-LEM can be connected anywhere along the LEM line and the terminal

connections are similar to those of the D-LEM except that the "in" and "out" connections are

both made on the left-hand terminal strip only.

The DIL switch settings establish the address of the Q-LEM. Only switches 1 through 7 are

used. Switch number 8 controls the tamper switch. When switch number 8 is OFF, the tamper

switch is in series with zone input A (terminal 5); therefore, on a Q-LEM cover tamper alarm,

the panel will display a DISCON for zone A. The general formula for determining the zone

numbers from the address (decimal) value is the following:

Zone A Terminal 5 = (Address Value x 2)

Zone B Terminal 7 = (Address Value x 2)-1

Zone C Terminal 8 = (Address Value x 2)+2

Zone D Terminal 10 = (Address Value x 2)+1

The coding table on page 27 may be used to determine the switch settings.
