XLS-278 and XLS-270

Manual Pull Stations

SPECIFICATION DATA

DESCRIPTION

The XLS-270 and XLS-278 series Manual Pull Stations are

part of Honeywell's Signature Series system. The XLS-270

Fire Alarm Manual Pull Stations feature a "teardrop" shape.

They are made from die-cast zinc and finished with red epoxy

powder-coat paint complemented by aluminum colored

stripes and markings.

With positive pull- lever operation, one "pull" on the station

handle breaks the glass rod and turns in a positive alarm,

ensuring protection plus fool-proof operation. Pre-signal

models (XLS-270P) are equipped with a general alarm (GA)

key-switch for applications where two-stage operation is

required. The "up-front" highly visible glass rod discourages

tampering.

Honeywell's double action single stage XLS-278 station is a

contemporary style station made from durable red colored

Lexan. To initiate an alarm, first lift the upper door marked

"LIFT THEN PULL HANDLE", then pull the alarm handle.

FEATURES

• Single stage double action XLS-278 features a rugged

Lexan housing

• XLS-270 models have traditional familiar appearance

• XLS-270 models are available for one stage (GA),

two stage (pre-signal), and double action

• Break glass operation on XLS-270 models

• Intelligent device with integral microprocessor

• Non-volatile memory

• Automatic device mapping

• Electronic addressing

• Stand-alone operation

• Diagnostic LEDs

• Designed for high ambient temperature operation

• Designed to ISO 9001 standards

The integral microprocessor built into each Signature Series

station provides four important benefits: Self-diagnostics and

History Log, Automatic Device Mapping, Stand-alone

Operation and Fast, Stable Communication.

Self-Diagnostics and History Log:

Each Signature Series manual station constantly runs self-

checks to provide important maintenance information. The

results of the self-check are automatically updated and

permanently stored in the station's non-volatile memory. This

information is accessible for review any time at the control

panel, PC, or by using the SIGA-PRO Signature

Program/Service Tool.

The information stored in the station's memory includes:

- Station serial number, address, and station type.

- Date of manufacture, hours of operation, and last

maintenance date.

- Number of recorded troubles, alarms, and time and

date of last alarm.

- Up to 24 possible trouble codes which can be used to

specifically diagnose faults.

Automatic Device Mapping:

The loop controller learns where each device's serial number

address is installed relative to other devices on the circuit.

The loop controller keeps a "map" of the Signature Series

devices connected to it.

Signature Series Data Entry Program also uses the mapping

feature. With interactive menus and graphic support, the

wired circuits between each device can be determined.

Layout or "as-built" drawing information showing the

branches (T-taps), device types and their address are stored

on disk for printing hard copy. This takes the mystery" out of

the installation. The preparation of "as-built" drawings is fast

and efficient.

Device mapping allows the Signature loop controller to

discover:

- Unexpected additional device addresses.

- Missing device addresses.

- Changes to the wiring in the circuit.

Stand-alone Operation:

A decentralized alarm decision by the station is guaranteed.

On-board intelligence permits the station to operate in stand-

alone mode. If loop controller CPU communications fail for

more than 4 seconds, all devices on that circuit go into stand-

alone mode. The circuit acts like a conventional alarm

receiving circuit. Each station on the loop will still transmit an

alarm if its operating lever is pulled.

Fast Stable Communication:

Built-in intelligence means less information needs to be sent

between the station and the loop controller. Other than

regular supervisory polling response, the station only needs

to communicate with the loop controller when it has

something new to report. This provides very fast control

panel response time and allows a lower baud rate (speed) to

be used for communication on the loop.

The lower baud rate offers several advantages including:

- Less sensitivity to circuit wire characteristics.

- Less sensitivity to noise glitches on the cable.

- Less emitted noise from the analog wiring.

- Twisted or shielded wiring is not required.

Diagnostic LEDs:

Twin LEDs provide visual indication of normal and

alarm/active conditions. They are visible only when the

station is removed from the mounting box. A flashing GREEN

LED shows normal system polling from the loop controller. A

flashing RED LED means the station is in alarm/active state.

Both LEDs on steady shows alarm state in stand-alone

mode.

Installation:

The Signature Series fire alarm manual pull stations mount to

North American 2-1/2in (64 mm) deep 1-gang boxes and 1-

1/2in (38 mm) deep 4insquare boxes with 1-gang covers. The

terminals are suited for #14 to #18 AWG (1.5 mm2 to 0.75

mm2) wire size.

Honeywell recommends that these stations be installed

according to local codes.

NOTE: This module will not operate without electrical power.

As fires frequently cause power interruption, we

suggest you discuss further safeguards with your

fire protection specialist.

Electronic Addressing:

The loop controller electronically addresses each station,

saving valuable time during system commissioning. Setting

complicated switches or dials is not required. Each station

has its own serial number stored in its "on-board memory".

The loop controller identifies each device on the loop and

assigns a "soft" address to each serial number. If desired, the

stations can be addressed using the SIGA-PRO Signature

Program/ Service Tool.

Application:

The operating characteristics of the fire alarm stations are

determined by their sub-type code or "Personality Code".

NORMALLY-OPEN, ALARM-LATCHING (Personality code 1)

is assigned by the factory; no user configuration is required.

The device is configured for Class B IDC operation. The

ALARM signal is sent to the loop controller when the station's

pull lever is operated. The alarm condition is latched the

station.

Testing and Maintenance:

To test (or reset) the station, simply open the station using a

special tool and operate the exposed switch.

The station's automatic self-diagnosis identifies when it is

defective and causes a trouble message. The user-friendly

maintenance program shows the current state of each

Signature series device and other pertinent messages.

Single devices may be deactivated temporarily, from the

control panel. Availability of maintenance features is

dependent on the fire alarm system used.

Scheduled maintenance should be planned according to

local codes.
