2.7 Wiring Controller Tamper and AC Power Fail Inputs
2.7.1 LNL-3300-M5 ISC
The LNL-3300-M5 has two dedicated inputs for enclosure tamper (TMPR) and UPS fault monitoring
(PFLT). If these inputs are not used, install a jumper wire.
To connect the tamper and UPS fault monitoring inputs:
1. Connect the tamper switch to the LNL-3300-M5 on TB1-6 (GND) and TB1-7 (TMPR). Only use a
Normally Closed contact.
2. Connect AC power fail input from a battery backup unit to the LNL-3300-M5 on TB1-6 (GND) and
TB1-8 (PFLT).
The battery backup unit must supply either a Normally Closed dry contact or a sense line that is low
(GND), meaning no AC power failure.
3 Battery connections
4 +12 VDC output connections
5 AC power fail connections (Normally Closed contacts only)
6 LNL-1100-20DI Input/Output Module (TB1 shown)
7 TB1-1: Input 1 ground (return) connection
8 TB1-2: Input 1 point connection
9 Install 2K resistors at power supply terminal block
10 +12 VDC backup battery
11 TB1 on LNL-3300-M5 (or LNL-8000-MCOM in downstream controller enclosure)
12 TB1-3: +12 VDC connection
13 TB1-4: Ground connection (GND)
14 TB1-6: Ground connection (GND)
15 TB1-8: AC power fail input connection (PFLT)
16 FCC and CE compliance: shield grounds must be stripped back through the knockout hole
(strain relief) and grounded to external ground studs provided.
