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.
•Use 4146 keyswitch or any N.O. keyswitch.
•Use only one keyswitch per partition.
•When using a keyswitch, the zone it is connected to is no longer available for use as a protective zone.
•Use *56 Menu mode to program the keyswitch zone and assign it zone type 77.
•Use *80 Menu mode to program the LED functions: program outputs 17 and 18 for system operation zone type 78 (red LED) and 79 (green LED) as appropriate (see Output Device Programming section).
