# Disarm/Re-Arm Setting

When your RTU is operating normally, the RTU is considered "armed." There will be times when you will need to take the unit out of service. You may want to temporarily prevent the unit from calling personnel. This is accomplished by "disarming" the RTU.

The DISARM/RE-ARM button on the RTU front panel is used to toggle the RTU between ARMED and DISARMED states. You can also toggle states with Alarmware™ and from Over the Phone (OTP) programming.

The Catalyst can also be programmed to re-arm itself automatically. See Annunciation Options.
