Installation
3.8.1 Releasing Operations
Approved releasing solenoids are list in the Device Compatibility Document. Do not mix cross alarming zones with smoke verification
zones. There must be at least two automatic detection devices in each protected space. Spacing must be reduced to 0.7 times the linear spac-
ing in accordance with NFPA 72.
An MRD-1 Manual Release Disconnect Switch can be used to disconnect the releasing circuits for testing and maintenance. Do not rely on
disable/enable software settings to lock out releasing devices. Releasing devices must be physically disconnected per UL 864 10th Edition.
Refer to the MRD-1 Installation Document #LS10231-000GE-E for more information.
3.8.2 Conventional Notification Appliances
This sub-section of the manual explains how to install the conventional notification appliances for Class A and Class B configurations.
Class B Notification Wiring
Use UL listed notification appliances only. Circuits are supervised, power-limited, and regulated. Refer to the Device Compatibility Docu-
ment for a list of compatible notification appliances.
To install a Class B notification appliance circuit, wire notification appliances as shown in Figure 3.10 and configure the circuit in FACP
programming.
UL listed EOL
4.7 kΩ
Class A Notification Wiring
Use UL listed notification appliances only. Circuits are supervised, power-limited, and regulated. Refer to the Device Compatibility Docu-
ment, for a list of compatible notification appliances.
To install a Class A notification appliance circuit, wire notification appliances as shown in Figure 3.11 and configure the circuit in FACP
programming.
NOTE: In programming, any point that uses multiple I/O circuits are always referred to as the lowest I/O circuit number used. For example,
Figure 3.11 uses both I/O circuit 5 and 6, so in programming it would be referred to as point 5.
