Description
TELEFIRE TLD-08
The TELEFIRE TLD-08 is a versatile addressable IO module that provides multiple outputs and switch inputs for supervision and indication purposes. The module has a modular design and can be used in various configurations according to installation requirements. The TLD-08 main board contains 8 unsupervised open collector outputs and can optionally be expanded with additional cards.
Key Features
Modular Design: The TLD-08 family consists of a main card and optionally three different daughter boards:
- TLD-08 main board: SLC connectors, 24Vdc connectors, and 8 unsupervised open collector outputs
- TLD-E16: 16 open collector expansion module
- TLD-R8: 8 dry contact relay module
- TSM-E16: 16 switch input add-on module
Flexible Addressing: The module occupies 4, 8, 16, or 24 consecutive addresses, depending on hardware configuration and switch settings.
Programmable Operating Modes: Operating modes are selectable via switches or jumpers on the modules, including number of addresses or switch input modes.

Installation and Programming
Address Programming: Configure the module’s first address using a PROG-4000 device programmer or the control panel’s address programming port.
Control Panel Definitions:
- Inputs: Define as “Switch” type with various modes (Alarm, Reset, Silence, etc.)
- Outputs: Define as “Lamp”, “Supervisory Output”, or “Control Out” as appropriate
Cabling Requirements:
