FAQs

How many zones does Alexor support?

Alexor supports wireless zones 1 through 32, plus optional use of I/O points as zones 33 and 34.

Can I use the onboard I/O as outputs?

Yes. The same points can be configured as low-current PGMs at 50 mA each — not simultaneously as zones.

Why did my keypad fail to enroll?

The first keypad must usually be enrolled within about 2 minutes after power-up. If missed, power cycle and repeat.

What order should I enroll wireless devices?

Keypad first (power-up window), then [804]: siren → sensors → pendants → keys.

Which communicator modules are typical?

TL265, TL265GS, GS2060, and GS2065 are optional signaling modules.

What is the AUX current limit?

200 mA total auxiliary — budget sirens, communicators, and external devices accordingly.

Can I add hardwired zones?

Only via onboard I/O as zones 33/34 — not a full hardwired expander like PowerSeries PC5108.
