PRODUCT DESCRIPTION
The FG-1025Z is a directional glass-break detector. Two
microphones and time-of-arrival processing allow the unit to
provide precisely-defined protected and excluded zones.
For a detailed description of how the FG-1025Z works, refer to
the Technical Information section on page 5.
MOUNTING LOCATION
For the greatest flexibility in aiming the FG-1025Z, mount the unit
on the ceiling. Figure 3 illustrates the protected, excluded and
keepout zones for a ceiling mounted FG-1025Z.
The arrows printed on the intermediate cover (see Figure 1)
indicate the direction of the protected zone. Refer to the
Mounting Guidelines to select an appropriate location, and refer
to the Aiming Guidelines to aim the unit properly. (
If ceiling
mounting is not possible, the unit can be mounted on a wall or post.)
WIRING
1. For surface-wired installation, use optional Wiring Spacer
Plate (model number FG-SP2).
2. Route wire through Wire Entry Hole in the center of the
printed circuit board (PCB), and strip wire ends 1/4" (6.5 mm).
3. Wire the unit as shown, (use 22 - 18 AWG). Reverse polarity
connections will not damage the unit.
4. When wiring is complete, push excess wire back into the
ceiling. (Refer to the Mounting Locations section.)
NOTE: If end-of-line resistors are required, wire as shown in Figures
2c and 2d.
