The 4 inches Detector Bases (FZBU004-AB4/FZB013-2Z/FZB013-4Z) are used to mount the smoke or heat detector to the electrical back box.
The FZBU004-AB4/FZB013-2Z/FZB013-4Z terminals are intuitively marked for easy installation and quick connection. The bases will accept 14to 22 AWG wire. The FZBU004-AB4/FZB013-2Z/FZB013-4Z offers a wide coverage area to completely cover the back box and the surrounding
surface. The FZBU004-AB4/FZB013-2Z/FZB013-4Z will mount on a single gang, double gang, octagon or 4 inches square box.

The Addressable Isolator Base 6 inches (FZBU005-AIB) is a base with an integrated isolator module included. The base has a locking feature
for the detector that may be used or removed in the field. Once the head is removed, the isolator is accessible in the bottom of the unit.
The isolator will open the Signal Line Circuit (SLC) down stream when a short circuit is detected. This will provide devices between the control
panel and the isolator to continue to operate. The short is indicated by a steady amber LED and once the short is removed the unit will return tonormal operation.

Locking FeatureFZBU005 - ASB

FZBU series include a locking feature that prevents removal of the detector and removal of the base cover without using a tool.
1. To eliminate this feature, break off the locking tab (refer to Figure 2), and then install the detector.

ADDRESSABLE SOUNDER BASE

Break the plastic tab by twisting it toward a centerof the base

2. To remove the detector from the base once the locking feature has been activated, insert a small screwdriver into the slot on the base to push
the plastic tab while simultaneously turning the detector head counter-clockwise (refer to Figure 3).

Features• Integrated sounder in base• 75 dB (UL 464 listed)• Sounder independent of detector• May be mapped to any device connectedto the control panel

Description
The Addressable Sounder Base 6 inches (FZBU005-ASB) is a sounder base that may be utilized in a variety of applications. The base has alocking feature for the detector that may be used or removed in the field. Once the head is removed, the sounder is accessible in the bottom ofthe unit.
The base has an independent sounder that can be programmed as a single station, zone or all call sounder. The sounder produces a minimumof 75 dB at 3.1m (10 feet). The FZBU005-ASB passes through the sound pattern sent to the sounder, therefore, it may reproduce in any
pattern the power supply provides.
The panel will support any combination of detectors or modules on the SLC. The FZBU005-ASB occupies one address on the loop. Once
activated the sounder will also follow the input from the power source and de-activate accordingly.

3. To remove the base cover from the lower enclosure once the locking feature has been activated, insert a small screwdriver into the slot on theon the base to push the plastic tab while simultaneously turning the detector head counter-clockwise (refer to Figure 4).

Setting the Address for FZBU005 Series
Each addressable module, smoke detector, heat detector and combination detector must have the address set before connecting the device tothe Signaling Line Circuit (SLC) loop. The address is set using the hand held device programmer or the addressing feature on the control panel.

Sound Pressure level

Detector Base Mounting

The sound pressure level is minimum 85dB at anywhere of 3 meter away from the sounder base.
This complies with the CAN/ULC-S525 Clauses7.5 (refer to Figure 1).

Detector base should be mounted directly on the electrical box.
The mounting holes are configured for a single gang, double gang, octagon or 4 inches square box.
