Local mode operation is limited to general alarm. Any point type listed in Table 4 is valid for
local mode alarm operation. Note that the point must be an alarm-type point. On any alarm
input, all circuits listed in Table 5 will activate.

Input Operation
:
During local mode operation, TrueAlarm initiating devices connected to the transponder will
cause an alarm at their least sensitive alarm threshold.
- Photoelectric sensors will alarm at 3.7%/ft smoke obscuration
- Ionization sensors will alarm at 1.3%/ft obscuration
- Heat sensors will alarm at a fixed temperature of 135° F (57° C).
•
Notification Operation:
Notification appliance circuits operate per the point type selected in the programmer, with the
exception of 20 BPM march time, which operates at 60 BPM.
If a NAC is programmed for SQALERT point type, the audible appliances will sound as
programmed and the strobes will flash synchronized at 1 Hz.
Voice NACs play the horn tone at temporal-coded cadence.
•
TrueAlarm sounder bases are limited to “on steady” operation. A coded NAC must be used to
drive the 24V power to the sounder base if coding is necessary. TrueAlarm device LEDs
operate as usual.
