Customer Critiques


SS-770 Acceptable really Economical Smoke Alarm, extended battery life
The Universal SS-770 Ionization Smoke and Fire Alarm is ordinary but unusually smaller: 4-inch diameter, 1-inch thick, white plastic. Quite economical $four.45 from HmDpt 6/16/ten. Manufacturer generic six page insert: [...]
This smoke alarm works but is as standard as feasible: 9V battery only, ionization detector only, no LED at all, no hush button. Just a weekly test button and the alarm beeper. It comes with a standard non-alkaline 9V carbon-zinc battery that will need to final for about 4 years. A greater-excellent battery would last longer. The alarm itself is supposed to be replaced ten years after the date of manufacture. It comes with a worthless five year warranty which demands a payment of $4. Produced in China.
The missing hush button is the worst feature of this alarm. You are supposed to mount it on the ceiling, or within 12 inches of the ceiling. But if it goes off given that you burned the toast, it could be difficult to reach! Even right after you have figured out how to rip it off the wall (twist and pull), the irritating alarm can't be silenced till you figure out how to disconnect the battery, which is not simple and easy to do if you are in a bad mood.
The smoke alarm mounts on a round white plastic base plate, which is screwed to the wall or ceiling with two lengthy skinny screws that are only partly threaded. The screws operate OK on walls but would not securely mount in to ceiling sheet-rock. Secure mounting would need larger screws and/or plastic sheet-rock inserts.
A battery-operated smoke alarm like this is a terrific life-saving tool for individuals who sincerely want to have this sort of protection. But if you are a landlord dealing with tenants who could not correctly replace batteries as necessary, or somebody who just never ever wants to be bothered with taking care of gear, you need to have alarms that are wired into the AC power.
For the reason that this is an ionization (radioactive) sort of smoke alarm, it makes use of pretty small battery power. There is no have to have to replace the battery twice a year that would be wasteful. The 9V battery need to commonly last substantially longer than one particular year. If you are comfortable making use of a volt meter, measure the battery twice a year and replace it when it gets considerably beneath 9.0V. The SS-770 should go on working until the battery gets down to about 7.5V, at which point it will start chirping about each and every 40 seconds.
Based on current measurements, an ordinary "heavy duty" 9V battery should really last about four years, a decent alkaline battery ought to final about 6 years, and a super-duper Lithium battery really should final over ten years.
These are actual power measurements:
9.5V 6microAmps + existing spikes
Low-power measurements:
three.2-three.6V (three.two-3.8V) quiet quickly chirp
3.6-5.2V (three.8-6.2V) three beeps, pause repeat
five.two-7.3V (6.two-7.7V) rapid chirp every single 41 seconds - time to replace the battery!
^volt range going down^ (^volt range going up^)
non-techical translation: do not let the battery voltage get beneath eight volts

I like the low price and the alarms are basic and do what they are supposed to. I would order additional of this type for my household in the future.
