You can use POPIT (Point of Protection Input Transponder) modules to provide up to 126
POPITs connect to supervised
If a POPIT is disconnected from the expansion loop, a trouble message appears immediately. See the D9112 Program Entry Guide
If you connect a POPIT that is programmed for a point number that does not appear in the program for the D9112 to the expansion loop, it appears as an extra point at the command centers when the point is faulted, and during the service walk test.
Placing a short on the data expansion loop generates a PT BUS TROUBLE report. The panel sees all points on the shorted expansion loop as shorted, and responds according to point programming.
POPIT modules monitor their sensor loops for three conditions, loop normal, loop open, and loop shorted. They report these three conditions to the D9112. A ground on a POPIT sensor loop reports as an open.
The D9112 uses point programming to interpret the sensor loop information reported by the POPITs and make the appropriate system response.
D8125 POPEX Module
D8127 POPIT Modules
D8127 POPITs use the D8125 POPEX module to report to the D9112. Each D8125 supports up to 63 POPIT points. Connect two D8125 modules to the D9112 to bring the combined total number of POPIT and
There are two versions of the D8127 modules. Both module enclosures are made of UL listed fire resistant material. D8127T modules contain tamper switches. D8127U modules come with an untampered cover. Unless the module is mounted in a tampered enclosure, UL requires D8127T modules for certificated accounts.
POPEXs manufactured prior to the expiration date (located on the packaging box) of X9434 may cause POPITs to report as missing after the AC has failed and after the panel goes into a low battery condition but before the panel goes into load shed. POPEXs manufactured after X9434 will not cause missing POPITs prior to load shed on an AC FAIL.
