SMD-426/427 PG2
Supervised Wireless PowerG Smoke Detector /
Heat and Smoke Detector
1. INTRODUCTION
SMD-426 PG2 (smoke detector) and SMD-427 PG2 (heat and smoke detector) are automatic fire detectors with integral audible signal for open
area protection, designed to sense heat or smoke (not flame) and fitted with a PowerG type transceiver.
SMD-426 PG2 / SMD-427 PG2 provides early warning of developing fire by sounding an alarm with its built-in alarm horn, and by transmitting a
coded alarm signal to a PowerG receiver or to a compatible wireless alarm control panel.
SMD-427 PG2 will activate a fire alarm upon either smoke or heat (temperature rate-of-rise) condition. With two fire sensors (heat and smoke), the SMD-
427 PG2 detector may shorten the time to fire alarm activation.
It must be borne in mind, though that effective pre-warning of fire accidents is only possible if the detector is located, installed and maintained as
described here.
In alarm condition, the buzzer sound can be stopped for 12 minutes by pressing the
TEST/MUTE switch. It will not restore the alarm condition, but will temporarily silence the
buzzer while you correct the condition. After 12 minutes, the detector restarts the alarm
buzzer sound.
Note: The TEST/MUTE switch functions as TEST switch (in normal operation) or as
MUTE switch (in alarm condition).
The detector can also operate as a siren to indicate a fire alarm in other areas covered by
the alarm system, or to indicate burglar alarm events, as configured through the control panel
(see the PowerMaster Installer Guide).
The tamper switch actuator (Figures 9a and 9b) is pressed against the bracket when the
unit is attached to the bracket. Removal of the unit from the bracket causes the switch
contacts to open, creating a tamper event, which is reported by the transceiver to the
alarm system control panel.
Note: When the tamper switch is opened the detector becomes not ready for operation.
2. INSTALLATION
2.1 Disassembly
Separate the unit from its mounting bracket as shown in Figure 2.
2.2 Where to Install Smoke Detectors
WARNING! To comply with FCC and IC RF exposure compliance requirements, the smoke detector should be located at a distance of at least 20
cm from all persons during normal operation. The antennas used for this product must not be co-located or operated in conjunction with any other
antenna or transmitter.
Smoke detectors should be installed in accordance with the NFPA Standard 74 (National Fire Protection Association, Batterymarch Park, Quincy, MA
02169). For complete coverage in residential units, smoke detectors should be installed in all rooms, halls, storage areas, basements and attics in each
family living unit. Minimum coverage is one detector on each floor and one in each sleeping area and attics in each family living unit. For maximum
protection, a smoke detector should be located outside primary sleeping areas or on each level of your home. Here are a few useful tips for you:
Install a smoke detector in the hallway outside every separate bedroom area, as in Figure 3. Two detectors are required in homes with two bedroom
areas, as in Figure 4.
Install a smoke detector on every floor of a multi-floor home or apartment, as shown in Figure 5.
Install a minimum of two detectors in any household.
Install a smoke detector inside every bedroom.
Install smoke detectors at both ends of a bedroom hallway if the hallway is more than 12 meters (40 feet) long.

- Page 3 Dead air spaces are often at the top of a peaked roof, or in the corners between ceilings and walls. Dead air may prevent smoke from reaching a detector. See Figures 6 and 7 for recommended mounting locations. In insect-infested areas. If insects enter a detector's sensing chamber, they may cause a false alarm. Where bugs are a problem, get rid of them before putting up a detector.

SMOKE DETECTOR TEST Notes: i) Insert the battery and then mount the detector on the bracket before conducting the smoke detector test. ii) After the battery is inserted, the detector enters the Local Diagnostic Test Mode for 15 minutes. iii) It is recommended to test the detector when conducting the Periodic Test using the User Code (User Diagnostic Mode) or when conducting the Periodic Test using the Installer Code (Installer Diagnostic Mode).
- Page 6 F. In general, detectors may not always warn you about fires caused by carelessness and safety hazards like smoking in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing with matches or arson. G Smoke detectors are not fool-proof. Like all electronic devices, smoke detectors have limitations. No type of smoke detector can sense every kind of fire every time.
