Question: What other features do the First Alert® OneLink® alarms have?
Answer:
First Alert® OneLink® alarms other key features include:
• A photoelectric smoke sensor. The competition uses ionization sensors.
Photoelectric sensor technology is nuisance resistant around kitchens and
bathrooms, which traditionally are more prone to nuisance alarms from
cooking smoke and steam from showers. Nuisance issues with tenants is time
consuming and costly. Some areas of the country require photoelectric alarms
near high nuisance areas like kitchens and bathrooms.
• Requires only 2 “AA” batteries vs. 3 AA batteries with the competition. This
saves 33% in annual battery replacement costs. For large apartment
complexes, this can add up to thousands in savings per year.
• Two Silence features: Alarm Silence can quiet nuisance alarms for several
minutes. Low Battery Silence can temporarily silence the low battery chirp
for up to eight hours before replacing the battery. This is a key feature when
the low battery chirp begins in the middle of the night and you do not have
any replacement batteries. You can quiet the chirp and then replace the
batteries when it’s more convenient.
• Perfect Mount mounting bracket allows for adjustments to the alarm
orientation without it disconnecting from the mounting bracket. This allows
for a cleaner installation.
• Tamper resistant pins to lock the battery drawer and alarm to mounting
bracket. This is a requirement in many multi-family installations.
