Keyswitch Notes
UL
A UL Listed keyswitch is required for fire installations and UL commercial and residential
burglar alarm installations. The Ademco 4146 keyswitch is UL Listed.
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.
