All low voltage wiring should be stripped back ¼ from the end for insertion into the removable plug. NEVER allow bare wire

to extend above the connector plastic shell. Wires shorted together may result in improper operation or permanent damage to

the UltraGuard 12V.

WIRING CAUTION:

· Open (unscrew) the terminal strip clamp before inserting wire

· Never bend wire back on the insulation

· DO NOT allow insulation to be trapped in the connector clamp

· After tightening the terminal strip clamp, tug on the wire to verify a good connection

CAUTION: Always observe the separation of the furnace 120VAC wiring and the low voltage wiring. The 120VAC

wiring MUST be kept to the right of the barrier and the low voltage wiring to the left of the barrier. NEVER remove

the barrier or operate the system with a damaged or removed barrier.

ELECTRICAL CONNECTIONS

The UltraGuard 12V has been designed to simplify the installation process. All low voltage

connections are made using removable plugs (a typical application is shown in Figure 16). This

avoids having to balance the panel while attaching wire. Only the 120VAC furnace control wiring

is permanently attached to the UltraGuard Monitor printed circuit board.

CAUTION: All wiring to the removable connectors is accomplished by stripping

¼ of insulation from the wire to be connected. Never allow bare wire to extend above

the connector shell.

Before beginning to wire the Monitor place the Zoned/Basic

jumper J6 (Figure 17) in the correct position for this installation

(see Understanding The UltraGuard Zones section, page 7).

If the Zoned/Basic jumper is to be moved; first move the jumper

J6 to the desired function, then once the unit is powered up,

push and hold the reset button until the UltraGuard Monitor

goes through its self test routine (lights flash in sequence and

beeper sounds). The J6 setting is now stored in permanent

memory.

NOTE: Unused zones do not require jumpers or resistors.

REMOTE PIEZO ALARM OPERATION

Selecting the external alarm with jumper J8 (in the Ext. Alarm position - figure

17 above) allows up to three piezo alarms to be attached to the Zone 4 input (J3).

The (-) side of the piezo must be attached to the end terminal (return) and the (+)

terminal must be connected to pin 13 (+12). Zone 4 is a monitored input and must

be terminated with two resistors as shown in Figure 18. The unique piezo resistor

(150 ohm 1W, Brown-Green-Brown) EOL resistor must be placed across the

terminals of the last piezo (as shown in Figure 18). The two middle terminals of

the Zone 4 connector must have a 15K (Brown-Green-Orange) resistor.

CAUTION: The piezo alarm load must not exceed 300 mA (0.3A) @ 12 Volt. This output is protected by a self-

resetting PTC fuse device.

When the system is in alarm, pressing the reset button on the UltraGuard Monitor will silence both the local and external piezo.

If Zone 4 is used for an external alarm it cannot be used for a CO Detector input.
