NOTICE:
This manual should be left with the owner/user
of this equipment.
IMPORTANT
: This detector should be cleaned at least once a
year. If cleaning is performed with non-intrinsically safe
equipment, it must be conducted outside the hazardous area.
General Description
Model 1151EIS ionization smoke detectors use state-of-the-
art sensing chambers. These detectors are designed to af-
ford open area protection and are for use with compatible
two-wire control panels only. Each detector is equipped
with two LEDs that provide a local, visual indication of de-
tector status. Remote LED annunciator capability is also in-
cluded. Once the detector senses a fire, it latches in alarm
and remains in this condition until it is reset by a momen-
tary power interruption. The detector can be tested by acti-
vating an internal reed switch with a test magnet.
NOTE:
Although the 1151EIS is a UL listed smoke-auto-
matic fire detector, UL has not evaluated this prod-
uct for use in hazardous environments. The
detector is FMRC and BASEEFA approved for in-
trinsic safety.
Installation
NOTE:
All wiring must comply with all applicable na-
tional codes of practice and regulations.
WARNING
Disconnect the power to the initiating device before install-
ing the detectors.
1. Detector Installation
A. Install the base following the base installation instruc-
tions.
B. Position the detector in the base receptacle.
C. Rotate the detector clockwise until it moves into
place.
D. Continue rotating the detector clockwise until it locks
in place.

2. Tamper-Resistance Feature
This detector includes a tamper-resistance feature that
prevents its removal from the bracket without the use of
a tool. To make the detector tamper-resistant, remove
the smaller tab by breaking it at the scribed line on the
tamper resistance tab before installing the detector. The
tamper-resistance tab is on the detector mounting
bracket.
To remove a tamper-resistant detector from the bracket, use
a pocket screwdriver, or similar tool, to depress the tamper-
resistance tab and turn the detector counterclockwise. The
tab is accessible through the slot on the mounting bracket.
CAUTION
Dust covers are an effective way to limit the entry of dust
into smoke detector sensing chambers. However, they may
not completely prevent airborne dust particles from enter-
ing the detector. Therefore, System Sensor recommends the
removal of detectors before beginning construction or other
dust producing activity. Be sure to remove the dust covers
from any sensors that were left in place during construction
as part of returning the system to service.
Testing
Before testing, notify the proper authorities that the smoke
detector system is undergoing maintenance, and that it will
be temporarily out of service. Disable the zone or system
undergoing maintenance to prevent unwanted alarms.
IMPORTANT
: If testing is done with non-intrinsically safe
methods, it should be conducted outside the hazardous area.
Detectors must be tested after installation and following
periodic maintenance. Test the detector as follows:
A. Test Magnet (Model M02-04-01 or M02-09-00)
1. Position the test magnet against the cover in the loca-
tion shown in Figure 1.
