wireless interconnect, voice with location and silence features are
required and with model building codes published by the ICC.
First Alert SCO500NVA is a state of the art wireless talking smoke
alarm designed to provide early warning of a fire. It features a fully
insect screened Photoelectric smoke sensing chamber, an 85dB horn,
a supervised 3V (2 AA batteries) power supply, a full function test
switch and a silence feature. This smoke alarm interconnects via
wireless communication on a reliable and secure radio frequency
communication of 915 MHz frequency with 65,000 security codes
and 3 channel frequency hopping. There is a choice of 11 pre-
programmed locations where a voice will announce the location
and danger detected. When interconnected with other First Alert
Wireless Interconnect alarms it will also announce the danger and
location detected of that alarm too. It operates on a Mesh Network;
a two-way communication format that sends, receives and re-sends
the alarm signals providing a more reliable network. It also features
tamper resistant locking pins that lock alarm to the mounting bracket
and battery drawer to prevent removal of battery or alarm. Perfect for
apartment, dormitory or hotel applications. Designed for wall or ceiling
mounting. Includes mounting anchors and screws.

2. Wireless interconnect: 915 MHz frequency with 65,000 security codes and 3 channel frequency hopping.
3. A Voice Warning of danger detected in addition to speaking one of 11 preprogrammed locations, e.g.
“Warning, Evacuate, Smoke in Basement”.
4. Operates on a Mesh Network; a two-way communication format that sends receives and re-sends the
alarm signals providing a more reliable network.
5. The unit shall have a lower and varying horn frequency to make it easier for the elderly with normal age
related hearing loss to better hear the horn.
6. The CO sensor is adjusted not to detect CO levels below 30 PPM and will not alarm when exposed to
constant levels of 30 PPM for 30 days. It will alarm at the following levels: 400 PPM CO between 4 and
15 minutes, 150 PPM CO between 10 and 50 minutes and 70 PPM CO between 60 and 240 minutes.
7. The unit shall have an “End of Life” signal. This signal should be capable of temporarily being silenced for up
to 2 days. After about 2 days, the signal will resume. After about 2-3 weeks the signal cannot be silenced.
8. A fully screened sensing chamber to resist entry of small insects.
9. Powered by 2 replaceable AA batteries, a solid state horn rated at 85dB at 10 ft and should be capable
of self restoring.
10. A visual LED power-on indicator to confirm unit is receiving power or is in alarm.
