II. INSTALLATION.
A. Unpacking.
After unpacking the sounder, examine it for damage that may have occurred in transit. If equip-
ment has been damaged, do not attempt to install or operate it. File a claim immediately with
the carrier stating the extent of the damage. Carefully check all envelopes, shipping labels and
tags before removing or destroying them.
B. Electrical Connections
To avoid electrical shock, do not attempt to connect wires when power is on.
Failure to heed this warning may cause serious injury or death.
A terminal block is supplied on the LP4 for field wiring. Strip 1/2" of insulation from the wir-
ing leads. Attach the appropriate wires to the corresponding terminals. Tighten the screws to
insure that the wires are firmly held in place. The terminals will accept conductor sizes
23 AWG to 13 AWG.
C. Mounting Arrangements.
The base of the LP4 provides six (6) slotted recesses for mounting, and one (1) 15/32" cable
access hole.
III. TESTING/OPERATING.
Under certain conditions these devices are capable of producing sound loud enough to cause
hearing damage. Adequate hearing protection should be worn if standing within close
proximity to the device while testing. Recommendations in OSHA Sound Level
After completion of installation be sure to test the system to verify that each sounder unit operates
