3: Ann-Bus Annunciators/Modules; Ann-Bus Wiring - Honeywell Fire-Lite Alarms ES-1000X Manual

Installation
The following steps must be followed when installing the 4XTMF module:
1. Remove all power (Primary and Secondary) from the FACP before installing 4XTMF.
2. Carefully plug the connectors on the 4XTMF module into connectors J12 and J13 on the ES-1000X main circuit board, being careful
not to bend any pins.
3. Secure 4XTMF module to standoffs with supplied screws.
4. Slide SW2 on the ES-1000X main circuit board to the down position.
5. Enable 4XTMF supervision in user programming. Refer to "4XTMF Supervision" on page 77.
6. Reapply power to the FACP.
7. For proper 4XTMF operation, the output relays must be programmed for the factory default settings: Alarm Relay 1, Trouble Relay 2
and Supervisory Relay 3.
8. When the installation has been complete, enable the 4XTMF module by sliding the disconnect switch on the module to the left.
9. Test system for proper operation.

ANN-BUS Wiring

This section contains information on calculating ANN-BUS wire distances and the types of wiring configurations (Class B).

Calculating Wiring Distance for ANN-BUS Modules
The following instructions will guide the installer in determining the type of wire and the maximum wiring distance that can be used with
FACP ANN-BUS accessory modules.
To calculate the wire gauge that must be used to connect ANN-BUS modules to the FACP, it is necessary to calculate the total worst case
current draw for all modules on a single 4-conductor bus. The total worst case current draw is calculated by adding the individual worst case
currents for each module. The individual worst case values are shown in the following table:
In general, the wire length is limited by resistance, but for heavier wire gauges, capacitance is the limiting factor. Maximum length can never
be more than 6,000 feet (1,800 m), regardless of gauge used. The following formulas are used to generate the wire distances

1 When powering the ANN-BUS from one of the (non-resettable) DC power outputs at TB11, the
total worst case current draw cannot exceed 1.0 amp. If sharing this DC output with other devices,
the worst case current drawn by these devices must be combined with the ANN-BUS current draw,
and the total cannot exceed 1.0 amp. If the total current demand exceeds 1.0 amp, refer to
"Powering ANN-BUS Devices from an Auxiliary Power Supply" on page 32.
