Technical Specification
1.
The Smoke Alarm carries the BSI Kitemark to indicate type testing to BS EN14604: 2005. It will meet the requirements of Grade D (and exceed the
requirements of Grades E and F) as defined in BS 5839: Pt.6: 2004. It carries the CE mark to indicate conformance to Low Voltage and Electromagnetic
Compatibility Directives.
2.
Dual ionisation chamber sensor, with corrosion resistant electrodes, and insect resistant cover.
3.
230V AC Mains Power Supply with 9V Alkaline Battery standby supply capable of lasting up to 4 years in standby mode and capable of powering the
alarm for up to 2 years without mains power.
4.
Alarm is supplied with an `
Easi-fit
` built-in surface mounting plate, with integral terminal block and cable cover. The Alarm connects to the mains and
interconnect/control connections automatically as it slides on to the mounting plate. The Alarm disconnects from the mains and interconnect/control
connections as it slides off the mounting plate, without the need for a lead and connector.
5.
All mains wiring is covered by a cable cover so that the mains cable is not visible when the Alarm is removed from the ceiling, obviating the need for a
ceiling pattress or dry lining box.
6.
Encased horn assembly gives a minimum sound output of 85dB(A) at 3 metres. The diameter of the piezo disc in the sounder measures 35mm, and is
securely held with silicone mastic to prevent creepage and premature horn failure. Additionally, soldered contacts are used in order to eliminate failures
due to corrosion and arcing that are associated with commonly used pressure contacts.
7.
Interconnection capability such that if one alarm sounds all interconnected alarms sound. Up to 20 alarms, ionisation, optical or heat can be
interconnected in this way.
8.
Automatic self-test feature tests the chamber every 40 seconds and unit bleeps (without red LED flash) if it is degraded.
9.
Manual integral Test/Hush button tests circuitry, sensor and horn and activates all interconnected alarms in the system. Also operates 'Hush' feature to
silence nuisance alarms. Red LED on alarm cover will flash every 10 seconds to indicate that alarm is in 'Hush' mode and will automatically reset after
approximately 10 minutes.
10.
Remote alarm activation can be achieved by using a manual call point MCP401RC. See separate specification sheets for more information on these
options.
11.
Remote ‘Locate’ facility via an Ei159 Locator Switch to audibly identify source of alarm signal when system is sounding. All units except the alarm that
has triggered and sent out the interconnect signal will be silenced.
12.
Alarm has a RadioLINK wireless interconnect capability when used with an Ei168RC RadioLINK base. In this case other RadioLINK products can be
connected.
13.
Separate green LED mains indicator light on the alarm cover to confirm integrity of mains power supply.
14.
Separate red LED on the alarm cover will flash every 40 seconds to indicate full auto test of circuitry and the battery. The red LED will flash rapidly in
alarm condition and flash once every ten seconds whilst the unit is in a de-sensitive (Hush) condition.
15.
Low power cell warning signal operates with or without mains power present.
16.
Anti tamper locking device prevents unauthorised removal of the alarm without the use of a tool.
17.
Foam gasket built into ‘Easi-fit’ plate to prevent dust ingress into the rear of the alarm.
18.
Ambient temperature range: 0°C to 40°C (32°F - 104°F). 0% to 95% (non-condensing) relative humidity.
19.
Dust cover is fitted to the alarm to protect it from contamination during installation.
20.
Supplied with two separate sets of instructions - one for the installer and one for the user.
21.
Dimensions: 140mm dia. x 43mm depth.
22.
Weight inclusive of packaging: 370g.
