Universal Security Instruments USI-2430 owner manual Installation, Electrical Shock Hazard

INSTALLATION

Installation of this unit must conform to the electrical codes in your area; Article 760 of the National Electrical Code, NFPA 72, 101; SBC (SBCCI); UBC (ICBO); NBC (BOCA): OTFDC (CABO), and any other local or building codes that may apply. Wiring and installation must be performed by a licensed electrician. Failure to follow these guidelines may result in injury or property damage.

This unit must be powered by a 24-hour, 120V AC 60Hz circuit. Be sure the circuit cannot be turned off by a switch, dimmer or ground fault circuit interrupter. Failure to connect this unit to a 24-hour circuit may prevent it from providing constant protection.

iMPORTANT: Do not subject this alarm to megger, high voltage or high- pot tests. Remove the heat alarm(s) before high-potting tests occur on the circuit or system. (Ref. Section 550-17 National Electric Code, 2002 Edition).

ELECTRICAL SHOCK HAZARD

Turn off power to the area where you will install this unit at the circuit breaker or fuse box before beginning installation. Failure to turn off the power before installation may result in serious electrical shock, injury or death.

TAMPER LOCKING PIN: To make your heat alarm somewhat tamper resistant, a locking pin has been provided. Using this pin will deter children and others from removing the alarm from the mounting ring. To use the pin, insert it into the hole in the side of the alarm after it has been installed on the mounting ring. Note that the tamper pin will have to be removed in order to change the battery, which can be done easily with a pair of long nose pliers. Using the long nose pliers, pull the pin out of the hole. It is now possible to remove the heat alarm from the mounting ring.

1.Turn the heat alarm counterclockwise to remove it from the mounting ring. NOTE: The heat alarm is sealed and the cover is not removable. Your heat alarm is also equipped with a safety device which prevents mounting unless a battery is installed. If your heat alarm will not lock onto the mounting ring, check to make sure a battery is installed.

2.Wiring Instructions:

a.The appropriate power supply is 120 Volt single phase power supplied from a non-switchable circuit NOT protected by a ground fault circuit interrupter.

b.Turn off main power to the circuit before wiring the heat alarm.

c.There are three pigtail leads (black, white and yellow) coming from the AC QUICK CONNECTOR. The proper wire connection is as follows:

WIRES FROM QUICK CONNECTOR	CONNECT TO
BLACK	"HOT" side of AC line
WHITE	"NEUTRAL" side of AC line
YELLOW	Interconnect wires of other units

For units that are used as single heat alarms, do not connect the yellow wire to anything. Insulate this wire (tape it) in place to make certain the yellow wire cannot contact any metal parts.

Interconnected units can provide earlier warning of fire than stand-alone units, especially if a fire starts in a remote area of the dwelling. This heat alarm may be interconnected with as many as 12 other USI model smoke alarms such as USI-1103, USI-1203, USI-1204, USI-1208, USI-1209, USI-1213, USI-3204, USI-5204 and 6 other units which may be a combination of Carbon Monoxide Alarms such as USI-7385, USI-7390, USI-7485, USI-7490, USI-7795, Heat Alarms/USI-2430 or Relay Modules/ USI-960 for a total of not more than 18 interconnected devices.
