Once assigned to a door, the on-board Lock output and
Egress input will automatically be assigned to the same
door as the keypad.
If both alarm area and door control is required then
you will need to assign a home area and a door to the
keypad.
The CP155B LED indicators will only display the
status of the programmed home area. You can-
not move between areas from this keypad. If you
require multiple area status visibility you should use
a display keypad like the CP700B.
Keypad Alert Tones
The CP155B keypad emits several distinct tones to alert
you to particular system events. The keypad volume lev-
el cannot be adjusted on the CP155B however it can be
turned off via panel programming by setting the keypad
volume to the lowest level. See Devices-Commands-
Volume menu in panel programming.
Setting the keypad volume to off will also stop the
key press beep during normal operation.
Keypad Alert Tones
Event Alert Tone Emitted
Fire
Alarm
If the system registers a fire alarm, the
reader will sound 3 short beeps fol-
lowed by a 1.5 second pause. This will
repeat until reset by the user or until
the siren run time expires.
Burglary
Alarm
If the system registers a burglary
alarm, the keypad will sound a con-
tinuous siren tone until reset by a user
or until the siren run time expires.
Trouble
If a system trouble condition occurs,
the keypad will sound 4 x fast short
beeps followed by a 5 second pause
and will repeat this tone until the user
acknowledges the trouble
condition from a display keypad
Key
Press
The keypad will sound one short beep
every time a button is pressed.
Exit
Delay
The exit delay warning will sound 1
short beep every second when the
area the keypad has been assigned to
is armed. During the last 10
seconds of exit time the warning tone
will speed up indicating that the time
has nearly expired.
Entry
Delay
The hi/lo entry delay warning tone will
sound once every second when an en-
try delay zone in the area the keypad
has been assigned to is triggered. If
the system is not disarmed before the
entry time expires then an alarm will
occur.
Error
If you press an invalid button during
any data entry sequence, the keypad
will sound a 2 second warning tone
indicating that the command was not
accepted.
Chime
Alert
If chime mode is active then the
keypad will sound fast short beeps
to alert the user when a zone pro-
grammed for chime is opened. Chime
mode is only applicable when the area
is disarmed.
Table 7: Keypad Tones
When keypads are installed outside the premises,
you may prefer that the alert tones are disabled.
See the Devices-Keypads & Readers-Indicator Op-
tions menu in panel programming to disable these
features.
Egress and Lock Control
The CP155B includes a lock output and egress input
which can be used to simplify the wiring when the
keypad is being used for access control. The lock output
consists of a Form 1c Relay capable of handling 2Amps
@ 24v DC which can drive a door lock or trigger a third
party device like a gate controller. The output is a clean
change over relay contact that is electrically isolated and
will operate for a fixed 5 seconds whenever the associ-
ated door is operated
The on board lock output will operate for a fixed
time period of 5 seconds when triggered. If a dif-
ferent time is required then you should use another
output on the system to operate the door lock.
Depending on the system load, the panel power supply
may not be sufficient to operate the door lock, espe-
cially in cases where it is power to lock and a separate
power supply should be fitted. When operating DC door
strikes the back EMF energy generated when the lock is
released should be shunted with a reverse diode and is
not always provided by the door strike manufacturer.
The Egress input [Green Wire] on the CP155B keypad al-
lows you to simplify the wiring required to implement an
egress button on the inside of the door. The egress input
triggers the lock output on the keypad by operating the
associated door that has been assigned to the keypad.
The egress input should be connected via a momentary
