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.

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.
