Frequently asked questions
Is the GS509A magnetic or screw-mounted?
Is the GS509A magnetic or screw-mounted?
The manual specifies screw mounting: two 5 mm holes 75 mm apart, wall plugs, a mounting plate and screws, then a twist-lock. It does not list a magnet or adhesive mount.
What battery does the GS509A use?
What battery does the GS509A use?
It uses a replaceable 9V carbon-zinc battery; the manual lists Eveready 1222 and GP1604S and warns against lithium batteries. A fresh battery provides about one year of operation. Replace it within 7 days of the low-battery chirp.
Does the 10-year rating mean the battery lasts 10 years?
Does the 10-year rating mean the battery lasts 10 years?
No. The 10-year figure is the product service life; the 9V battery lasts about one year. Replace the battery annually and replace the complete alarm after 10 years.
Where should I install the GS509A?
Where should I install the GS509A?
Ceiling mounting is preferred. Keep it at least 4 inches from the side wall; on a wall, 4–12 inches below the ceiling. Install at least 6 feet from cooking and heating appliances, and avoid bathrooms, high-humidity areas and temperatures outside 4.4–37.8°C. Do not use it in an RV or boat.
Will cooking smoke set off the GS509A?
Will cooking smoke set off the GS509A?
It can. The photoelectric sensor responds to smoke particles, but frying or broiling smoke can still trigger it if the unit is too close to the kitchen. Keep it at least 6 feet from cooking appliances; for a nuisance alarm, press TEST/SILENCE and ventilate. Do not remove the battery.
How do I test the GS509A?
How do I test the GS509A?
Press and hold TEST/SILENCE for longer than 2 seconds, once a week. The alarm should sound three long beeps and the red LED should flash. If it does not sound, check the battery and replace the unit if the fault continues.
Why is my GS509A chirping?
Why is my GS509A chirping?
A periodic chirp usually means low battery; replace the 9V battery within 7 days. If a fresh battery does not stop the chirp, the alarm may have a fault and should be replaced. Do not remove the battery and leave the unit without protection.
How do I silence a false alarm?
How do I silence a false alarm?
Press TEST/SILENCE once to silence the alarm for about 8 minutes, then ventilate the area. Dense smoke overrides the silence. Never remove the battery to stop an alarm.
Does the GS509A interconnect with other alarms?
Does the GS509A interconnect with other alarms?
No. The GS509A is a standalone alarm and does not interconnect by wire or wireless. It protects the area where it is installed; use an interconnected model for whole-home coverage.
What should I do if the GS509A alarms?
What should I do if the GS509A alarms?
Treat every alarm as a real fire. Get everyone outside, call 911, and stay out until firefighters say it is safe. Do not remove the battery or re-enter to look for smoke. If you know the alarm was caused by cooking, ventilate only after everyone is safe.
What standard and warranty does the GS509A carry?
What standard and warranty does the GS509A carry?
The manual lists UL 217 9th Edition and CAN/ULC S531-19. The warranty is 36 months limited from purchase and excludes the battery. Keep your receipt for any claim.
