External Sounders 

  System Sensor sounder 
  Multi-Tone Local Alert (MTLA) 

PLEASE NOTE:  

If desired, the LC unit can drive an external 
sounder. Accutech provides two types of 
external sounders: the System Sensor sounder 
and Multi-Tone Local Alert (MLTA). 

An external sounder will alarm simultaneously 
with the internal peizo of the LC unit when an 
alarm occurs and is silenced by a Keypad Reset.  

An external sounder will not be silenced by 
removing jumper JP2 (Tone Enable), however, 
removing this jumper will disable audible 
notification of all internal alarms (i.e., Egress, 
Tamper, Power Loss Supervisor, and Perimeter).
