4-FT firefighter telephone live voice announcements
For an EST4 system that includes a firefighter telephone, the telephone paging feature permits individuals with
access to a remote firefighter telephone to make announcements over the emergency voice/alarm
communications system.
Notes
• All 4-FT live voice announcement functions require a 4-24L series control-display module.
• Your system may be configured differently than described below.
To make a live voice announcement:
1. For a control unit programmed as a command center, request for control of the EST4 system may be
required. Use a 4-24L series control-display module to request control. See Figure 11 below.
If the top Control Status LED (item 1) is steady, proceed to step 2. If not, press Request Control (item 2); its
LED flashes while requesting control. When the top Control Status LED is steady, proceed to step 2.
