Honeywell Sensor FSP-951

Before removing the detector, notify the proper authorities that the smoke detector system is undergoing maintenance and will be temporarily out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms.

Sensor cover removed by pressing firmly on each of the four removal tabs that hold the cover in place

Screen vacuumed carefully without removing it

Chamber cover/screen assembly removed by pulling it straight out

Dust and debris removed from the sensing chamber using a vacuum cleaner or compressed air

Chamber cover/screen assembly reinstalled by sliding the edge over the sensing chamber. Turn until it is firmly in place

Cover replaced using the LEDs to align the cover and then gently pushing it until it locks into place

Before testing, notify the proper authorities that the system is undergoing maintenance, and will temporarily be out of service. Disable the system to prevent unwanted alarms.

All sensors must be tested after installation and periodically thereafter. Testing methods must satisfy the Authority Having Jurisdiction (AHJ). Sensors offer maximum performance when tested and maintained in compliance with NFPA 72.

The sensor can be tested in the following ways:

A. Functional: Magnet Test (P/N M02-04-01 or M02-09-00)

This sensor can be functionally tested with a test magnet. The test magnet electronically simulates smoke in the sensing chamber, testing the sensor electronics and connections to the control panel.

1. Hold the test magnet in the magnet test area as shown in Figure 3.

2. The sensor should alarm the panel.

Two LEDs on the sensor are controlled by the panel to indicate sensor status. Coded signals, transmitted from the panel, can cause the LEDs to blink, latch on, or latch off. Refer to the control panel technical documentation for sensor LED status operation and expected delay to alarm.
