Installation and Operating Instructions
Read this instruction sheet thoroughly before installation and use of the SMD-429 PG2
Introduction
The SMD- 429 PG2 is a wireless photoelectric smoke and heat detector with a fixed tem-
perature and rate of rise heat detector, and an internal piezoelectric alarm.
Three versions are available: a 915 MHz for US version (UL) and Canadian version (ULC), a
433 MHz and 868 MHz for International version (EU) and a 433 MHz for Australian version
(AUS).
Compatible Devices
The smoke detector is compatible with Visonic Control Panels and Power G receivers.
HUSH/TEST BUTTON
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 12 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 LED flashes once per second and the sounder sounds the evacuation temporal pat-
tern.
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 LED flashes every 8
seconds for up to 10 minutes, to indicate the alarm has been silenced.
The flashing LED stops when the unit returns to normal operation. The alarm silence feature
has a fixed time setting that desensitizes the smoke alarm for 8 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 12 hours, the panel will display a loss of supervision
message.
