PG9936/PG8936/PG4936 Series Wire-

less Smoke and Heat Detector

Installation and Operating Instructions

Read this instruction sheet thoroughly before installation and use of the

PG9936/PG8936/PG4936

Introduction

The PG9936/PG8936/PG4936 is a wireless photoelectric smoke and heat detector with a fixed

temperature and rate of rise heat detector, and an internal piezoelectric alarm.

The following versions are available:

Frequency (MHz) Version Region

915 PG9936 North America

868 PG8936 Europe

433 PG4936 Europe/International and Australia

Compatible Devices

This smoke detector is compatible with UL/ULC Listed DSC Wireless Control Panels and DSC

Wireless Receivers using PowerG Technology, PowerSeries Neo and iotega platform 3.

HUSH/TEST BUTTON

NOTE:

For UL/ULC installations use this device only in

conjunction with compatible DSC wireless

receivers: HS2128, HS2064, HS2032, HS2016

control units when connected to HSM2HOST9

wireless receiver, HS2LCDRF(P)9, HS2ICNRF(P)9

Keypads with integrated receiver, PG9920

repeater and Wireless Alarm Systems WS900-19,

and WS900-29. Transmissions occur at

approximately 915 MHz (912MHz to 919 MHz).

Operation

Approximately every 7 to 8 seconds the unit tests for a smoke or heat alarm condition. During

this sequence the unit also performs self diagnostics, and checks for tampers and faults. During

normal operation the green LED flashes every 60 seconds and the sounder does not sound.

Smoke Alarm

The smoke detector alarms when the signal level exceeds the “alarm” threshold and auto-

matically restores when the signal level falls below the alarm “restore” threshold. During an

alarm the red LED flashes once per second and the sounder sounds the evacuation temporal

pattern.

Alarm Silencing

This smoke alarm is provided with an automatically resettable alarm silencing feature. When the

sensor is in alarm, press the Test/Silence/Reset button to silence the local annunciation of the

alarm and transmit an alarm restore event to the control panel. The red LED flashes once per

second for up to 7 minutes, to indicate the alarm has been silenced.

After an alarm the red LED will flash once every 4 seconds to indicate an alarm in memory. The

alarm silence feature has a fixed time setting that desensitizes the smoke alarm for 7 minutes.

Alarm silencing does not disable the smoke alarm but rather reduces its smoke sensitivity. Fol-

lowing the silenced period the smoke alarm restores automatically to its intended operation. If

smoke around the unit is dense enough to suggest a potentially dangerous situation, it remains

in alarm, or may return to the alarm state quickly.

Detector Trouble

When the detector has a general fault, the yellow LED blinks once every four seconds and

there is a chirp every 48 seconds. After 4 hours, the panel will display a fire trouble message.

Detector Cleaning Required

When the detector is contaminated, the yellow LED blinks once every 8 seconds and there is a

chirp every 48 seconds. Refer to the MAINTENANCE section for cleaning the detector. After 4

hours, the panel displays a message fire clean.

Heat Alarm

The heat detector (cULus versions only) alarms when the heat signal level exceeds the heat

alarm threshold (135 ºF / 58 ºC); and will automatically restore when the heat signal level falls

below the heat alarm threshold (restore). The detector also goes into a heat alarm state when

there is a rapid increase in the temperature over a short period of time. During an alarm the

LED flashes 1/second and the sounder sounds the evacuation temporal pattern.

Tamper

The removal of the detector from the mounting plate initiates a “tamper” transmission. The

tamper condition is restored after the detector is mounted on the plate.

Wireless Transmissions

A supervisory message is transmitted at 128 second intervals for the PGx936. If the signal is not

received the control panel determines that the detector is missing.

The detector transmits the following:

Alarm / Alarm Restore - (heat or smoke alarm). Transmitted at time of occurrence.

NOTE: During an alarm condition, the detector sends an alarm event to the control panel.

When the condition is restored, the detector sends an alarm restore event to the

panel and sets the alarm restore indicator. The red LED blinks once every 4

seconds until the Alarm in memory is cleared. You can clear the alarm restore indic-

ator from the control panel, or press and hold the test button for 5 seconds.

Tamper / Tamper Restore - (tamper switch activated) 10 second maximum delay on restore

before transmission.

Low Battery - (battery voltage falls below threshold). Battery voltage is tested & transmitted

at the time of a supervisory or other transmissions.

Trouble - (detector fault or sensor compensation limit reached). Troubles are transmitted at

the time of occurrence (one trouble per supervisory interval).

Batteries

The wireless smoke heat alarm is powered by 3 AAA Duracell Procell PC2400 or 3 AAA Ener-

gizer E92 batteries (included). The detector regularly checks for a low battery. If a low battery is

detected, the transmitter sends a low battery message to the control panel, which displays the

detector's ID at low battery. In addition, the yellow LED of the detector blinks every 12 seconds.

The detector's sounder chirps every 48 seconds and the yellow LED continues to blink until the

batteries are replaced. Pressing the hush button silences the chirps for 12 hours, if no other

trouble conditions exist. The batteries should be replaced with new batteries when the chirps

begin.
