4098 TrueAlarm Sensor Bases

Introduction

TrueAlarm smoke/heat sensor bases are connected to a 2120 Multiplex Communicating Device
Transponder (CDT), 4020, 4100+, 4100U, 4100ES, 4120, 4008, or 4010 panel by a single wire
pair (MAPNET II/IDNet). The 4098-9792, -9789, 9793, 9796, 9797, and 9798 bases and their
sensors obtain both power and data over MAPNET II/IDNet wiring. The 4098-9791 sensor base
requires 24VDC power for relay operation and the 4098-9794 and 4098-9795 sensor base with
sounder requires 24 VDC or Notification Appliance Circuit (NAC) power. The 4098-9791, -9794,
-9795, and –9796 are NOT compatible with the 2120 CDT. The 4098-9793 is only compatible
with the 4010, 4008, 4100U and 4100ES (except with 4100-3103 Quad Panel Isolator).

Setting the Base's
Each sensor base has a unique address. This address is associated with a custom label that
Address
identifies its physical location within a building. The base's address and location must match up
with the address listed in the specification sheets of the 2120 Job Configuration Report or the
Programmer's Report for the 4020, 4100+, 4100U, 4100ES, 4120, 4008, or 4010 System. See
Figure 3-1 for DIP Switch location for 4098-9789, -9791, -9792, -9793, and -9796, Sensor Bases.
See Figure 3-2 for DIP Switch location for 4098-9794, 4098-9795, -9797 and -9798.
