Series 65 12V Relay Base
Installation Guide
General
The Apollo Series 65 12V Relay Base part no. 45681-508 is a 12V relay base for use with Apollo
Series 65 smoke and heat detectors only. The base is designed to operate over a voltage
range of 9V to 15V DC.
The use of a 12V relay base means that standard (latching) smoke and heat detectors can be
used for both non-latching and latching applications, such as security control panels.
Latching/Non Latching
The relay can be configured as latching or non-latching by means of an internal jumper link.
If the jumper is in the right hand position (Fig.1,Position A) the relay base is in the non-latching
mode.
If the jumper is in the left hand position (Fig 1, Position B) the relay base is in the latching mode.
If the jumper is not fitted, the base will default to non-latching.
Operating Principle
The relay base receives an alarm signal from the associated detector which latches.
In latching mode, the detector and relay remain latched until reset by removing the supply.
In the non-latching mode, when the associated detector has latched in alarm, the relay base
waits for approximately 15 seconds and then resets the detector by removing the supply auto-
matically. The detector will re-enter the alarm state if there is sufficient smoke or heat present.
Mounting Instructions
1. Secure the base to an even surface.
2. Connect the wiring following the diagram overleaf.
3. Ensure functional earth or screen continuity is maintained using the earth terminal on the
base if required.
4 . Fit the appropriate detector and lock it to the base using a hexagonal driver part no.
29600-095 if required.
