ABOUT THE KEYPADS

General Your keypads allow you to control all system functions. The keypads feature telephone style digital keys and a Liquid Crystal Display (LCD) which shows the nature and location of all occurrences.

The keypads feature a built-in sounder which emits alarm sounds during alarm and trouble conditions, and produces warning tones during entry and exit delay periods (if so- programmed). The sounder also provides acknowledgment tones when keys are pressed, and confirmation tones for successful command entries.

Keypad Styles There are various styles of keypads, any of which may have been used in your system (see page 7). Although different in appearance, all styles are functionally the same, except for their display windows (see “Keypad Types” below). The keys on some keypads are located behind a flip-down cover which can be removed, if desired.

Keypad Types There are two basic types of keypads, Alpha and Fixed-Word, either of which may have been used in your system.

•Alpha Keypads

These feature a 2-line, 32 character alphanumeric Liquid Crystal Display (LCD) which can display the nature and location of all occurrences in friendly English.

•Fixed-Word Keypads

These are functionally similar to the Alpha Keypads, except that their LCD display uses pre-designated (fixed) words to identify the nature and location of occurrences. Words displayed on all Fixed-Word keypads are the same, except that their location in the display window will vary with different models (see Styles A and B on page 6).

Unless stated otherwise, all commands and procedures described herein apply equally to all keypads.

Typical displays that would appear on both Alpha and Fixed-Word keypads are depicted throughout this manual.

This intelligent device combines advanced technology with user-friendly features, ensuring that homeowners can protect their families from fire and toxic gas threats effectively.

At the core of the FA145C is its dual-sensor technology, which utilizes both photoelectric and ionization sensors.

A standout feature of the First Alert FA145C is its voice alert system. This system provides clear announcements, indicating whether smoke or carbon monoxide has been detected. By minimizing confusion during emergencies, the voice alerts allow for quicker and more informed reactions, particularly in a panic-inducing situation.

The unit is equipped with a 10-year battery life, which reduces the hassle and costs associated with frequent replacements. The long-lasting battery ensures that the device remains operational for an extended period, contributing to peace of mind for homeowners. Additionally, the FA145C includes a convenient battery status indicator, alerting users when the battery is running low.
