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 12
hours, the panel displays a message loss of supervision.
Heat Alarm
The heat detector (cULus versions only) alarms when the heat signal level exceeds the heat
alarm threshold (135 ºF / 57 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 64 minute intervals for the SMD-429 PG2 and 12minute intervals for the other models. If the signal is not received the control panel determines
that the detector is missing.
The detector transmits the following:
l
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 per minute. You
can clear the alarm restore indicator only from the control panel.
l
Tamper / Tamper Restore - (tamper switch activated) 10 second maximum delay on restore
before transmission.
l
Low Battery - (battery voltage falls below threshold). Battery voltage is tested & transmitted
at the time of a supervisory or other transmissions.
l
Trouble - (detector fault or sensor compensation limit reached). Troubles are transmitted at
the time of occurrence (one trouble per supervisory interval).
Batteries
NOTE: The batteries must be replayed by service persons only.
The wireless smoke heat alarm is powered by 3 AAA Duracell Procell PC2400 or 3 AAA Energizer 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.
Battery Installation and Replacement
CAUTION:Risk of explosion if battery is replaced by an incorrect type. Dispose of used battery according to the manufacturer's instructions.
To replace batteries, complete the following steps:
1. Remove the detector from its mounting base by twisting the detector counterclockwise.
Carefully remove batteries by lifting from the “+” end using a flathead screwdriver and dispose of them according to local regulations.
2. To ensure a proper power-down sequence, wait a minimum of 20 seconds before
installing new batteries.
3. Install 3 new AAA batteries, available from a local Duracell or Energizer dealer in the battery compartment. Install the batteries by inserting the “-” end first, then pushing the “+”
end down. If the batteries are incorrectly inserted, please remove them carefully by lifting
