The Simplex 2098-9211 is a reconditioned two-wire mounting base for legacy Simplex conventional smoke detector heads. Specifically, it supports the Simplex 2098 series of two-wire ionization and photoelectric detector heads on conventional initiating device circuits.
In addition, the base is professionally reconditioned and functionally tested. As a result, it offers a budget-friendly path to keep aging Simplex 2098-series installations in service.
What the Simplex 2098-9211 Is — and Isn’t
First, this is a conventional two-wire base — not an addressable (MAPNET / IDNet) base. Therefore, it does not communicate device-by-device to a panel. Instead, the panel sees only zone-level alarm state on the initiating device circuit.
However, on a two-wire base the same pair carries detector DC power and the alarm signal. As a result, the wiring is simpler than four-wire designs that require a separate power pair.
Typical Compatible Detector Heads
The 2098-9211 was specified as the base for several Simplex 2098-series conventional detector heads. Please verify the specific head against your existing installation before ordering. Examples include:
- Simplex 2098-9201 ionization smoke detector head
- Simplex 2098-9202 ionization detector head
- Simplex 2098-9203 photoelectric detector head
- Simplex 2098-9208 photoelectric detector head
Specifications
- Function: Two-wire conventional smoke detector base
- Manufacturer: Simplex
- Part number: 2098-9211
- Configuration: Two-wire (conventional)
- Condition: Professionally reconditioned and functionally tested
- Compatible heads: Simplex 2098-series two-wire detector heads (verify before order)
When This Base Makes Sense
- Restoring a station damaged on an existing conventional zone
- Adding spare detector positions to an installed 2098-series circuit
- Extending the service life of a legacy Simplex conventional system
However, if a building is migrating to a modern addressable platform, the 2098-9211 is not the right base. Specifically, addressable detectors require an addressable base such as the 4098-9789 — not a two-wire conventional base.
