Wireless PowerCode Digital Mirror PIR Detector

1. INTRODUCTION

The TOWER 40 is a microprocessor-controlled wireless digital PIR
detector, designed for easy installation, free of vertical adjustment.
It features parabolic and cylindrical mirrors with uniform detection
sensitivity throughout its operating range, up to 18 meters (59 ft),
with creep zone protection.

The advanced True Motion Recognition™ algorithm (patented)
allows the TOWER 40 to distinguish between true motion of an
intruder and any other disturbances which may cause false alarms.

An on-board motion event jumper determines whether 1 or 2
consecutive motion events trigger an alarm.

The TOWER 40 includes the following features:

• Incorporating patent pending black mirrors for extremely high
white light immunity.

• Advanced elliptical / parabolic mirror technology (patent
pending).

• Provides multiple curtain coverage (patent pending).

• V-slot® optic technology (patent pending) for improved

robustness, anti-vandalism and for very high reliability.

• The entire electronic circuit is enclosed in the front cover with
the optics. The sensor element is isolated from gusts of wind
and insects.

• Creep zone protection.

• Back tamper switch to prevent

unauthorized removal from wall.

• Incorporates a fully supervised
PowerCode transmitter.

• Sophisticated frequency domain
digital signal processing.

• No vertical adjustment is needed.

• Battery compartment for easy

battery replacement without
access to the electronic circuit.

• Programmable motion event
counter.

• Specially constructed against
vandalism.

Very low current consumption

• Sealed chamber protects the optical system.

• Tamper switch for detector opening / removal alert.

• Improved white light protection.

• Elegantly styled, sturdy case.

3. INSTALLATION

3.1 General Guidelines

Do Not Install in the Following Locations:

3.2 Illustrated Installation Procedure

A. Rear Cover Removal

Release the screw 1 and remove the rear cover 2, as shown
below.

Figure 3 - Rear Cover Removal

Warning: Do not open the detector internal cover!

B. Mounting (see figure 4)

The detector can be mounted on a surface / corner, at height of

1.8 - 2.4 m (6 - 8 ft).
Place the detector rear cover on the mounting surface / corner.

Mark and drill 2 holes in the mounting surface / corner, insert wall
anchors and fasten the rear cover with 2 screws.

Caution To ensure proper functioning of the back tamper switch,
one of the screws should be in the break-away segment (see
point A in the illustration above).

Warning: The top of the detector (see below) must point
upward!

LED Functions Summary

After battery insertion and rear cover closure, the LED flashes for
2 minutes approximately until the detector stabilizes.

After stabilization, the detector enters automatically walk-test
period of 15 minutes (see par. G below). In this mode the LED
lights and the unit sends an RF alarm signal on every detection
(regardless of LED jumper position).

After the walk-test period, the LED operates according to the LED
jumper setting, as follows:

LED

Jumper

Position

ON

OFF

After the first 15 minutes, after every motion detection and alert
transmission, the detector disarms itself to save battery power. It
rearms (reverts to the ready state) if there is no subsequent
detection during the following 2-minute period. Therefore, if you
want to check the detector, you have to exit the room for at least
2 minutes and then enter the room.
