Menu flow chart INTRODUCTION The Lencore Model LP-2 Programmable Timer is a two zone electronic attenuator when attached to the blue and black wires of model LM-6 master sound masking units. Raising of masking levels is simulated only. That is, the highest level of sound masking is the same as if the timer were not attached to the blue and black wires of the masters. -

On line 3, Z1 refers to Zone 1, Z2 refers to Zone 2. The current values in dB's are shown for each zone. These values are referenced to an office masking level of 47 dB. That is, a reading of "Z1=0dB" and "Z2=0dB" on the timer display, means an office masking level of 47 db for both zones. - Page 5 The two zones must remain separate. If there is only one zone to connect to the timer, leave Zone 2 unconnected. This is very important. a) A 5-foot green wire is provided to attach the Timer Box to an earth ground.

steps. Locate the Test/Normal switch on the P.C. Board. Put the switch in Test position. The display will change showing both a dB level and a voltage level for each zone. This bypasses any programmed attenuation and allows for a total system calibration of the LM-6 master units. -
