Wiring

For UL installations, refer to section
60.1 Unsupervised Alarm Inputs: Power Fail and External (Cabinet)
Tamper
The Output Control Module features two (2) unsupervised alarm inputs that can be used for power fail and
external (cabinet) tamper monitoring. These inputs are connected using the PFL (power fail) and EXTMP
(cabinet tamper) contact terminals located on the Output Control Module.
The PFL and EXTMP inputs are simple N/C (normally closed) contact closure monitors.
Wire the PFL and EXTMP inputs using twisted pair cable, 30 ohms maximum (No EOL resistors are
required).
Connect the power fail monitoring device to J27 pins 1 & 3 and the External Tamper (cabinet tamper) pins 4
& 6. If not used, a jumper must be installed across pins 1 & 3 and 4 & 6.
