A UL Listed keyswitch is required for fire
installations and UL commercial and residential burglar
alarm installations.
If a keyswitch is used on:
• an installation that transmits opening and closing
signals, the keyswitch zone must be programmed to
send opening and closing signals.
• a UL commercial burglar alarm installation, the
keyswitch’s tamper switch must be connected in to
the alarm system. This tamper switch zone must
also be programmed for Zone Type 05 – Trouble by
Day / Alarm by Night.
• a fire alarm installation, the keyswitch must be
located next to an alphanumeric display keypad.
The Ademco 4146 keyswitch is UL Listed.
