Johnson Controls MPS-24A Installing Instruction

Installation—Installing the FC-2000 35
Figure 26: NFPA Style B Field Wiring of the IZM-8 Initiating Zone Module
Notes:
1. Initiating device circuits are supervised, power limited, and may be
connected to limited-energy cable. Initiating devices include
non-coded manual pull stations, heat detectors, photo and ion
detectors, and waterflow alarm and waterflow supervisory devices.
Connect waterflow alarm devices to a dedicated circuit programmed
for the waterflow option. Connect N.O. waterflow supervisory
devices to a dedicated zone programmed for supervisory operation.
Terminal Block will accept 12 to 22 AWG wire. Initiating circuit
current will ensure alarming of one 2-wire detector only.
