1 Introduction

The PYR-2021wired PIR is a high-performance intrusion sensor
made with the highest level of SMD Components as well as
Microprocessor Technologies making it ideal for both
residential and commercial usage.

The PYR-2021's SSFL technology (look down) allows detection
at proximity of 50cm from its mounting location.

The PYR-2021include selectable pulse counting as well as
cover and wall tamper detection features. The PIR also
features a removable Curtain adapter from inside the Lens
that will allow the device to be used for focused detecting,
such as across window surfaces or down corridors.

The following pages outline the
installation and test instructions for
your new PYR-2021 PIR.

3 Installation

3.1 General

The PYR-2021 is designed for easy installation. Only a few steps
are required to install the PIR device.

To enable the Curtain Adapter for PIR detection on a focused
area, such as a corridor, or across a window or opening, follow
the instruction outlined in section 4.

When you are sure of the mounting location, follow the steps
for mounting the PIR, on a flat surface or in a corner, described
below.

3.2 Opening the PYR-2021

The PYR-2021 housing can be opened by unscrewing a Philips­head screw (1) and pushing the safety latch (2) to “unlock”.

Removing the Lens

You will need to remove the lens only to add or remove the
Curtain Adapter.

1) Turn the top part of the PYR-2021 over and locate the

“holder pin” (A) for the lens.

2) Use a screwdriver to gently pop it out by putting the edge

under the “holder pin” and pushing down on the handle.

3) Turn the housing over and pop off the lens.

3.3 Wiring the PYR-2021PIR

The PYR-2021 is wired using a terminal block with binding posts
that are opened using a thin Philips head screwdriver or a flat
head screwdriver and located on the front of the PCB (see
PCB image below in the jumper section)

The terminal block consists of two Normally closed alarm relay
binding posts, followed by two Tamper binding posts and
closed off with a + and – 12VDC binding posts

Connect all the Signaling Cables first.

Wire the power last.

NOTE! When laying wires to the control panel ensure
that they are not in parallel with high voltage mains or
other high potential wiring as this may cause false
alarms.

3.4 Mounting the PYR-2021PIR

Select an area for mounting the PYR-2021, and ensure the
location is flat, either a wall or a 90-degree corner, for perfect
mounting of the unit. Ensure the PIR has a “view” of the area
under surveillance and is free from obstructions.

The PYR-2021 has a detection range of 14.7m (48 ft.) when
placed at a height of between 1.8m and 2.3m.

3.5 Wall Mounting

The PIR housing has “dimple” points for insertion of screws, for
either wall-mounting or corner mounting (refer to detailed
pictures below). Remove the PC board prior to mounting.

NOTE: Be careful not to touch the pyro-electric unit on
the board. Touching the unit will gravely affect its ability
of the unit to work properly.
