4098-9780 Simplex supervised relay base

Simplex 4098-9780 Supervised Relay Base is a 2-wire plug-in sensor base designed for use with TrueAlarm analog sensors. It works with a remote or locally mounted 4098-9860 relay and requires no separate power source.

This relay base offers programmable supervised relay operation, which can also be manually controlled from the fire alarm control unit. It includes wired connections for either a remote LED alarm indicator or a 4098-9822 relay (note: the 9822 relay is unsupervised and requires a separate 24 VDC power source).

Compatible control units include:

• 4007ES, 4010, 4010ES, 4100ES, and 4100U Series

• 4008 Series (with a reduced feature set)

• 4020, 4100, and 4120 Series control units

• Universal Transponders and 2120 TrueAlarm CDTs equipped for MAPNET II operation

This base is a reliable choice for integrating TrueAlarm sensors with Simplex systems in commercial fire alarm installations.
