"87" Displayed on Keypad and Rapid

Beeping Occurs (and/or the system can-

not be accessed by phone).

• The 4286 VIP Module is not responding to

the control panel. Check wiring of 4286

VIP Module to control (Data In, Data Out,

Aux [+], and Aux [–] wiring).

Keypad Produces Erratic Displays and

Beeps.

• Keypads used in system are non-

addressable type. Only addressable key-

pads can be used. If using a 4140XMP or

VIA30+ control, addressable keypads must

be set to the non-addressable mode.

Security System Cannot Be Accessed via

the Phone (on or off premises).

• The 2-digit Phone Code has not been pro-

grammed.

• 2nd digit of Phone Code (✴ or #) does not

provide touch tones on phone in use. Se-

lect whichever of these digits that does. If

neither does, that phone is not usable for

phone access.

Security System Cannot Be Accessed via

the Phone (from on premises).

• Entry of 2-digit phone code may be incor-

rect. Verify phone code and try again.

• Generally, the system cannot be accessed

when the phone line is busy, such as when

downloading is in progress, if engaged in a

phone conversation (except during entry

delay), or when the phone is ringing (al-

ways allow at least 10 seconds after the

last ring before attempting phone access)

• The system cannot be accessed if the

phone line is out of service.

Note: If the system cannot be access by

phone, verify the phones were properly

wired to the security system as shown in

the Summary of Connections. Phones in-

correctly wired (connected before the con-

trol panel or 4286 VIP Module) can NOT

be used to gain access to the system.

Security System Cannot Be Accessed via

the Phone (from off premises).

• Either the 2-digit phone code or system

security code may have been entered in-

correctly. Verify both codes and try again.

• Remote access turned off. If so, turn on

(from on-premises phone only) by entering

2-digit Phone Code to access system, then

enter: Master security code + # + 9 + 1.

Note: If turned off and TAMPER message

is displayed, clear system first by keying

an OFF sequence twice.
